Authors: Cholis Hafidz Wahyu Nur , Fauzıatı Endang , Suprıyadı Slamet
Published: March 2021

This study aims to explore teacher’s beliefs about students’ roles in learning English through MALL and the factors contributing to their beliefs. MALL which stands for Mobile Assisted Language Learning were the main instructional media where there was no such direct physical meeting in school. This media became popular nowadays, despite its emergence in the early 2000s, especially during Covid-19 pandemic which prevents both students and teachers to have direct physical meeting in the classroom. It was important to understand what role should be played by the students which in this research was viewed from teachers’ beliefs perspective. Therefore, the research questions formulated by the researcher were; (1) What are teacher’s beliefs regarding students’ roles in learning English through MALL? (2) What are the factors shaping their beliefs? In terms of methodology employed by the researcher, this research was qualitative with descriptive case study design. The subjects of this research were two teachers of Senior High School in Surakarta, Indonesia who were teaching English through MALL since 2017. The subjects were a Javanese male and Bataknese female who were 37 years old. Both of teachers had master degree from English Education Department. The instrument employed to acquire the data was interviews. The data then were categorized into the students’ roles based on the theories. The result indicated that four students’ roles became something that the teacher held as the truth. Those roles were participant, initiator, performer, and passive receptor. Meanwhile, the factors determining teacher’s beliefs were discovered five factors.

Authors: Ha Nguyen Thi Vinh
Published: March 2021

In 2018, ethnic minority region of Vietnam has the rate of poor and near-poor households 3.5 times higher than the national average. There are many studies that have pointed out the causes of high poverty in ethnic minority areas and proposed policies to reduce poverty. However, poverty among ethnic minority groups remains an increasing and prolonged challenge. This article applies the structural equation model to consider impacts of socio-economic changes on poverty reduction in ethnic minority areas in Vietnam over the past 5 years, to provide recommendations for poverty reduction policies for ethnic minorities. Research results show that in addition to improving the quality of education, strengthening management and improving the quality of cultural activities, focusing on improving the spiritual significance of cultural activities - festivals - movements and promotion of ethnic minority identity can be the key to poverty reduction in these regions.

The Situation of Securities Maket Supervision in Vietnam
Authors: Thi Thu Trang Dao
Published: March 2021

In order to ensure the transparency as well as the efficiency and maintain the stability of the securities market, the supervision system needs to be established with the goal of detecting, preventing and handling violations of regulations, laws enacted by the State. In Vietnam, the State manages the securities market and assigns the securities market supervision task to the State Securities Commission (SSC). Over the past time, the SSC has implemented several supervision operations and obtained certain results. However, the monitoring results also showed that the number of violations on the stock market tended to increase, reports on stability and risk identification were not yet or clear. Some reasons come from the limitations of the market surveillance system such as the lack of close coordination between the stock market supervision with banks, insurance, and the supervisory authority cannot develop the overall risk report form. Potential as well as systematic risk, control of different accounts of stock market participants is loosened, supervision focuses on issues with complaints or duplicating supervision that cause many subjects. It is possible to take advantage of the monitoring gap to make violations more sophisticated. The research results provide solutions to complete the supervision system of Vietnam's securities market to achieve the targets set in the coming time.

Published: March 2021

Different from previous studies in Vietnam, this paper focuses on fraud risk, identifying the factors that affect the risk of financial reporting fraud of listed companies in Vietnam. Moreover, the research aims to forecast the possibility of fraudulent financial statements of listed companies in Vietnam. Based on M-score models (Beneish, 1999) and F-score model (Dechow et al., 2011), this research develops experimental results based on a sample of 307 companies with 3684 financial statements observations from 2007 to 2018. Research results show that the higher financial leverage in firms’ financial statements, the higher risk of financial statements, and the higher fraud’s tendency. Moreover, the findings also show that perennial firms, bigger firms, and listed firms, they likely to have a higher tendency of financial statement fraud. Research results show that the higher the financial leverage ratio, the more errors in reporting, the higher the tendency for fraud. At the same time, the older a business, the larger its scale and listed on the stock exchange, the more likely it is that the financial statements are fraudulent.

Approach to: Heart failure
Authors: Hansen Delphine
Published: March 2021

Heart Failure (HF) affects more than 650,000 Canadians (3.6% of Canadian adults above age 40). Even with recent advances in the diagnosis and treatment of this disease, HF remains among the five most common causes for hospitalization in Canada, with a readmission rate above 30% at the 1-year mark. Despite the significant economic and clinical burden of this disease, there is limited awareness among healthcare providers, healthcare system managers, and governments regarding the current HF epidemic and available therapies. This article reviews the definition of HF and the approach to evaluating a patient with suspected HF, focusing on the different presentations of HF, the clinical significance of ejection fraction, and the usefulness of BNP as a marker of cardiac function.

Stevia is a natural sweetener which is used as a sugar substitute. It has been suggested that Stevia may be anti-cariogenic. However, there is limited research in this regard. Currently, Stevia rebaudiana, a plant is considered to be a suitable replacement of sugar which is healthy and has much fewer side effects than other sweeteners. To assess the salivary pH and streptococcus mutans growth among the participants after mouth rinsing with water containing natural sweetener. This double-blinded parallel clinical trial was done among forty female participants aged 22-25 years. Study participants were selected and randomly allocated by lottery method as two different groups as group A, and B. Microbial growth and pH of the saliva was assessed twice, once before rising with stevia solution and at 20 minutes after rinsing with a sugar solution containing Stevia (single tablet and two tablets) mixed in distilled water. Collected data were analyzed using the paired t-test. It was found from the study that there was an increase in mean salivary pH when compared with the baseline value after rinsing with Stevia. There was an increase in the Streptococcus mutans count after rinsing with Stevia. Increase in streptococcus mutans count was found to be low in Group A than group B. pH value stays in neutral value even after rinsing with a natural sweetener. There is no much difference between Group A and B. Salivary pH after mouth rinsing with Stevia is in a neutral state. It has low Streptococcus mutans growth suggesting that Stevia can also be used as a sugar substitute replacing artificial sugar substitutes.

COVID -19 pandemic is creating an uncertainty about the demographic trends of morbidity and mortality rates across countries worldwide. Hence, this study is aimed to characterize the gender and age distribution of morbidity and mortality from COVID-19 across populations. This cross-sectional study uses aggregate data on COVID-19 cases and deaths by gender and age. Considering gender-based morbidity, men diagnosed with COVID-19 substantially outnumber infected women with statistically significant findings (*p=<0.05, □ RR>2) in Asian, American, and African countries, whereas women diagnosed higher morbidity rate in European countries. However, gender-based fatality showed higher among men in most of the analyzed countries of all those continents except Australia where female fatality was higher. This study revealed 50 years old were mostly associated with the infection and death in all continents except Australia, showing more morbidity above 20 years of age, whereas, fatality rate was more in the above 80 years group. The study concludes that, across countries, COVID-19 morbidity and fatality rate is age specific rather than gender specific. Infection rates showed rising steeply with age; nevertheless, children do not stand on equal footing when COVID-19 crisis is transforming their day-to-day lives.

Published: March 2021

The aim of the present study is to evaluate the neuroprotective effect of methanol extract of Garcinia morella Desr  leaves in monosodium glutamate (MSG) induced neurotoxicity in rats. The MSG 2 g/kg, i.p. was used to induce the neurotoxicity. The rats were administrated with methanol extract of Garcinia morella Desr  leaves (MEGM) 200 and 400 mg/kg, p.o. and Dextromethorphan 30 mg/kg, p.o. after 1 h injection of MSG. The animals were evaluated for its behavioural factors such as muscle grip and locomotor activity. At the end of the study, the antioxidant enzymes levels, neurotransmitter levels, TNFα, ß-amyloid and mineral levels were estimated in brain homogenate. The MEGM treated group shows significant improvement of behavioural and locomotor activity and muscle strength against MSG induced neurotoxicity. The glutathione, SOD, catalase and total protein levels were significantly increased in MEGM treated group. However, significant reduction within the level of varied neurotransmitters like AChE, Dopamine, TNFα, ß-amyloid were observed on treatment with MEGM extract. Further, MEGM also significantly decrease the MSG induced toxicity through declined levels of Ca+2 and Na+ with increased levels of K+. In conclusion, the present study suggests that the MEGM  has significant neuroprotective activity against MSG induced neurotoxic rats.

Published: March 2021

Surgical Site Infections (SSIs) are one of the most common complications of any intervention in the maxillofacial region. Most of the times sutures used for wound approximation act as a nidus of bacterial accumulation and subsequent infection due to the presence of scores of microbes in and around the oral cavity. This has been attributed to the wicking action associated with braided sutures. Various methods to prevent surgical site infections are reported in literature, the most recent being use of antibacterial coated sutures. Sutures are either coated with triclosan or chlorhexidine or a combination of anti-microbial agents and fatty acids. These sutures are known to have a significant role in the prevention of SSIs elsewhere in the body, but the role in oral cavity remains questionable. This study aims to establish the role of chlorhexidine coated sutures in the prevention of surgical site infections if any. Chlorhexidine-coated and uncoated suture materials were used in 17 patients undergoing third molar extractions. Seven days post-operatively the sutures were removed, and bacteria were isolated. Following which colony-forming units (CFU/ml) were counted. Concerning the total number of oral pathogens, that adhered to suture material, no reduction was demonstrated for Chlorhexidine coated sutures. The use of chlorhexidine-coated suture material offers no advantage in intraoral surgery.

Knowledge of Breastfeeding and its practice among lactating mothers is an essential factor which determines the breastfeeding rates. Exclusive breastfeeding helps in preventing neonatal and infant mortality and morbidity and is one of the most important public health intervention, which can reduce the under-five mortality also. This study was conducted in Saveetha medical college hospital between March 2020 and June 2020. To assess the knowledge, attitude, Practice of Breastfeeding among lactating mothers. Descriptive cross-sectional study. 100 lactating mothers admitted to our hospital after delivery were selected randomly. They were interviewed based on a questionnaire which was prepared to assess the knowledge attitude and practice of breastfeeding. Informed consent was obtained after explaining the objective of the study. Out of 100 mothers, 71.38% had good knowledge, 66.6% showed a positive attitude towards breastfeeding, and 63.33% had acceptable breastfeeding practices. The breastfeeding practices followed in our hospital can be improved further by proper counselling and nutritional education of the mothers in the antenatal and immediate postnatal period. The comprehensive lactation management programme which has recently been started in our hospital could aid in the same. Dedicated lactation counsellor and lactation nurse could also help achieve improved breastfeeding practices and attitude towards breastfeeding.

Published: March 2021

Society imparts great importance to physical appearance in this modern age. The physical and psycho-social impact of a dentofacial deformity on an individual is often impossible to assess with certainty. A facial deformity can profoundly affect the quality of life and thereby entailing lifelong adjustments. Facial aesthetics affect an individual's confidence and their overall acceptance in society, which in turn has an apparent effect on their quality of life. Corrective jaw surgeries are indicated in cases not amenable to produce acceptable post-treatment results with orthodontics alone. Orthognathic surgery aims to produce a more aesthetic facial appearance and strives to improve stomatognathic functions in the process. WHO defines Quality of Life as- An individual's perception of their position in life in the context of the culture and value systems in which they live and concerning their goals, expectations, standards and concerns. It is a broad-ranging concept affected in a complicated way by the person's physical health, psychological state, level of independence, social relationships, personal beliefs and their relationship to salient features of their environment. The impact of dentofacial deformities on an individual's holistic emotional, physical and social development has been a focus of research for a long time. Several patients reported outcome scales are employed to assess the quality of life and this review aims to discuss the use of these scales as an indicator of successful surgical treatment. At the same time, these scales may serve as a patient education tool because a holistic health indicator is required which considers the psychological well being of the patient along with regards to functional and aesthetic demands before formulating a surgical treatment plan.

Muscle soreness appears after high-intensity unaccustomed exercise, especially eccentric exercise and it peaks between 24 and 72 hours post-exercise. It can result in reduced muscle power, range of motion hence impacting athletic performance. Different treatment strategies are available to alleviate symptoms of Delayed Onset Muscle Soreness (DOMS). The present study was done to draw a comparison between the effects of foam rolling and vibration therapy on pain, hip range of motion, sprint speed and lower limb power in subjects with exercise-induced muscle damage. It was a comparative Experimental Study design. The sample consisted of 30 Male students who were randomly allocated to 2 groups, i.e. Group A (Foam Rolling) and Group B (Vibration Therapy) with 15 participants in each group. Participants performed ten sets of 10 repetitions of back squats at 60% of their 1-repetition maximum, followed by either foam rolling or vibration therapy 24 and 48 hours post-DOMS protocol. Blood Creatinine level was measured before inducing DOMS(day 1) and after 24 hrs(day2) and 48 hrs(day 3) of recovery. Increase in serum levels of CK is used as an indirect marker of the microtrauma associated with DOMS. Pain, lower limb power, sprint speed and Hip range of motion were measured using Numeric Pain Rating Scale, Vertical Jump test, Sprint speed 30-meter test and goniometer respectively after 24 and 48 hours of recovery. Results showed both groups showed improvement on Day 2 and 3. However, Vibration therapy showed statistically better improvement compared to Foam Rolling group.

Кристаллографический анализ трех модификаций СаСО3 — ромбоэдрического кальцита (R–3c), ромбического арагонита (Pmcn) и моноклинного фатерита (C2/c) — показал разные механизмы упорядочений атомов в структурах. Важную роль в формировании той или иной структуры играет точечная симметрия энергетически стабильных атомных группировок (темплатов) в предкристаллизационной фазе, которая зависит от режима кристаллизации, примесей, локальных неоднородностей. Симметрия темплатов далее формирует симметрию структуры, размещая тяжелые атомы и центры масс стабильных атомных групп СО3 преимущественно в частные позиции с фиксированными координатами. Показаны детали этой кристаллодинамики — процесса упорядочения трансляционной и точечной симметрией позиций атомов.

Seckel Syndrome & Skull Morphology: Quantifying Characteristics
Authors:   Department of Pathology & Anatomical Sciences, University at Buffalo 955 Main St., Buffalo, NY 14203
Published: March 2021

Seckel Syndrome is a rare genetic disorder which causes morphological changes throughout the body. Some of the most commonly reported changes are those present within the cranium and mandible such as microcephaly, a beak-like nose with convex nasal ridge, and mandibular deformities such as micrognathia. However, these clinical terms provide insufficient information to allow for proper diagnosis or to understand the distortions in physiology that take place with the disease. Therefore, quantification of the features of the skull are necessary to further explain this pathology, and comparisons to normal variation will help to understand the degree to which the anatomy is affected. Seckel Syndrome is classified as a member of the microcephaly family of pathologies; however, our results demonstrate that the overall volume of the skull is not as significantly decreased as the cranial vault itself, which may provide the catalyst for Chiari Type I malformations. The mandible, likewise, is severely altered by Seckel Syndrome decreases in approximately 44% of its volume and demonstrating altered physical proportions. Finally, the osteological measurements of the facial features demonstrated inconsistent findings between different anatomical structures providing evidence that Seckel Syndrome may have a variable effect on the different bones and tissues of the skull.

Background: Avulsion fracture of the anterior superior iliac spine (ASIS) is a rare form of apophyseal avulsion fracture of the pelvis, and there is a lack of evidence-based guidelines for the selection of treatment options. There are various surgical procedures, but there is the risk of secondary removal of internal fixator and growth disturbance caused by epiphyseal fixation. Methods: We treated 5 patients with avulsion fracture of the anterior superior iliac spine by knotless suture bridge technique who visited our hospital from 2015 to 2020.The surgical treatment results were retrospectively analyzed. Results: 5 patients with fractures were healed after the surgery, no associated complications, the mean postoperative follow-up was 29.2 months (6-60months), all patients were not reported pain symptoms (visual analogue score of 0), they don’t have the limitation of daily activities, and the hip joint function recovered well, and very pleased with the results (Harris score 100 points) at the final follow-up. Conclusion: Knotless suture bridge technique is simple and effective in the repair of the avulsion fracture of anterior superior iliac spine. For such patients, this surgical technique can provide stable and reliable fixation, allow early recovery, and provide a feasible scheme for clinical practice.

Background: The objective of the research was to work out the set of test tasks assessing special physical fitness of 17-year-old soccer players. Material/Methods: At first, on the basis of the analysis of the said issue in literature and the authors’ own coaching experience, 13 test tasks were selected. Next, reliability and accuracy of the chosen test tasks were examined on the group of 16 athletes from the Centre of Sports training for youth in Gdansk. The reliability was assessed by the test-re-test method and the accuracy according to a criterion of internal accuracy tests. Except for one task, all efficiency tests met scientific requirements for motor tests. Finally, with the use of statistical analysis (linear regression equation, Hellwig’s algorithm of the optimal choice of explaining variables), four tests implementing most information for the assessment of game-play were chosen. Results: A four-task set of tests assessing selected components of physical fitness reflected 86.7% of the game-play of young competitors. Conclusions: Results of special physical fitness tests should be treated as important information about young athletes’ special physical efficiency, closely interdependent with the effectiveness of their activity in a classified game-play, but only when the tests themselves have previously been scientifically proved.

Background: The research aimed to determine motor skills that significantly affect the level of technical preparation in dancesport at the early stage of training. The applicable purpose was to determine the selection indicators in dancesport at the stage of initial training. Material/Methods: The study involved 50 dancesport contestants aged 6-9 years. The tests were carried out 3 times, at the beginning, after a year and after two years of training. Motor skills were assessed by means of: the Starosta’s test, a stabilographic platform, the IPTF trial, a trial testing the frequency of moves, a measurement of explosive strength of the lower limbs, ergometric measuring equipment “Concept 2 Dyno”, a test of simple reaction speed and of anticipation in space. Special fitness was determined on the basis of results of special fitness tests and standard anthropometric measurements were made by means of Martin’s method. A factor analysis was made of all the measurements; the correlation matrix was calculated with probability at p ≤ 0.05. Independent variables were confronted with the special fitness test results presented by the studied dancers. The multiple regression method was used, and for analysis the special fitness test result of 3 dance tournaments immediately after the 1st, 2nd and 3rd stage of laboratory tests and the results of these tests were taken. Results: The result of the special fitness test at the 1st stage of research is explained by multiple regression with independent variables in 66%, at the 2nd stage of research in 87%, and at the 3rd stage of research in 81%. The highest level of regression was reported at the 1st stage of research for the variable both legs coordination and at the 3rd stage of research for the variables balance and chené turns. Conclusions: 1. At the early stage of practicing dancesport, the greatest impact on the special fitness is exerted by: motor coordination, balance, flexibility, speed and strength skills, the body height and mass, the pelvis, torso, and chest indicators, and BMI. 2. The tests and indices applied in the research best reflect the specificity of dancesport and they can be recommended in the selection process for this sport discipline.

Published: March 2021

Background: Self-efficacy, defined as a personal resource, is increasingly analysed in context of healthseeking behaviours. Therefore, it is important to explain to what extent these behaviours are associated with cognitive personality disposition of physical education teachers, manifested by their self-efficacy. Material/Methods: We examined 271 physical education teachers (n♀ = 137 and n♂ =134) aged between 23 and 62 years (M = 38.97, SD = 9.33). The respondents were surveyed with the Generalized Self-Efficacy Scale by Schwarzer and Jerusalem in the Polish adaptation by Juczynski, Health Behaviour Inventory by Juczynski and the Multidimensional Body-Self Relations Questionnaire by Cash. Results: Our findings point to a beneficial effect of self-efficacy on Proper Nutrition Habits, Prophylactic Behaviour, Positive Psychological Attitudes and Fitness/Health Orientation. Nevertheless, the use of Indicator Variables in Regression revealed that GSES exerts stronger effect on health-seeking behaviours in men than in women. Furthermore, we did not confirm a crucial role of self-efficacy in undertaking physical activity and Health Practices. Conclusions: Physical education teachers show moderate levels of health-seeking behaviours; this necessitates stimulating their active involvement in self-promotion of health. This can be achieved by health promotional and educational activities addressed to physical education teachers.

Authors: LIPKO MARIA , DARMAS ANNA
Published: March 2021

Background: This study aims at determining opinion of participants of strengthening and relaxation classes on health determinants and their influence on adoption of particular forms of physical activity. Material/Methods: Participants of the study were 113 women aged 40 to 55, among whom 70 participated in such strengthening and relaxation courses as yoga, Pilates and Tai Chi and 43 women were inactive (control group). A survey prepared by the authors of this paper was used. Results: According to the participants, the most crucial factors influencing health are proper nutrition, adoption of physical activity and keeping proper body weight. Active women are aware of beneficial effects of regular physical activity, in particular regarding improvement of their mobility. Participants of strengthening and relaxation classes proclaim that physical activity drove them to a “healthy lifestyle” and especially to healthy nutrition habits. They recognise a pro-health meaning of physical activity, particularly in order to preserve fitness in the old age. Conclusions: Participants of the classes are aware of a pro-health value of regular participation in strengthening and relaxation courses. Pro-health policy of every country should strive to raise awareness of beneficial influence of regular physical activity and proper dietary behaviours on health status.
