Background: Orthodontics is a dental specialty focusing on correcting dental irregularities and malocclusion. Knowledge and attitudes towards orthodontic treatment are crucial for promoting oral health and overall well-being. Education and awareness play a vital role in ensuring optimal treatment outcomes and improving quality of life. Aim: This study aims to determine the knowledge and attitudes of Kwame Nkrumah University of Science and Technology (KNUST) pre-clinical dentistry students concerning orthodontic therapy. Methodology: This research is a quantitative descriptive cross-sectional study. The research used a non-random convenience sampling method to form the desired sample. For data collection, an interview-administered questionnaire was used over one month. The study set its sights on pre-clinical dental students in KNUST. A total of 150 questionnaires were printed to meet the sample size. Results: The results of the research showed that the knowledge level of KNUST pre-clinical students on orthodontic treatment and its nuances is quite limited. They however had a fair level of knowledge on the disease or ailment that orthodontic treatments solved (especially malocclusion). Their interest in orthodontic treatments on the other hand was quite significant, with a large number having interest in it. Conclusion: To conclude, KNUST pre-clinical students in Ghana although having a limited level of knowledge on orthodontic treatments have a keen interest in undergoing them regardless of the discomforts or the length of time. 展开更多

Motivation is considered an important factor for non-English major students in their language learning. In the study, questionnaires and interviews were used to explore the relationship between learning motivations of CDSI (Chengdu Sport Institute)'s non-English major students and their test scores in SCET-3 (Sichuan English Test-level 3). The results found that in general non-English major students' motivation is not high with no significant gender differences; their learning motivation shows some correlation with their vocabulary level; their external motivation has more impact on the non-English major students. Therefore, language learning motivation has a positive relation with students' English learning achievement. Considering the characteristics of the non-English major students, suggestions on English teaching methods are made to stimulate students' learning motivation and cultivate their learning strategies, so as to improve the quality of English teaching and students' English level. 展开更多

Background: In the hospital, patients are often exposed to multiple procedures, invasive devices etc., increasing their chances of contracting such potential pathogens. Most of the time these potential pathogens exhibit multiple drug resistance. Aim: In view of the above factors, this study was undertaken to determine the rate of colonization of potential bacterial pathogens in the hands of final year MBBS undergraduate students. As per their clinical teaching curriculum, they visit the wards/ICU/OT, etc. on a daily basis. Method: Samples were collected from the hands of final year MBBS undergraduate students. The samples were collected by rubbing a saline wet swab stick onto the hands of the students and were inoculated onto nutrient agar plates for 18 - 24 hours at 37°C aerobically. Bacterial isolates were identified till species level by performing gram staining and biochemical reactions. Antibiotic susceptibility testing was done by Kirby-baur disc diffusion method as per CLSI guidelines 2016. Conclusion: 103 samples were collected from hands of final year undergraduate MBBS students by swab culture method. 38 showed growth and 65 showed no growth. Out of 38 isolates, 36 were Gram positive cocci and 2 were Gram positive bacilli. No Gram negative bacilli were isolated. Amongst 36 Gram positive cocci, 16 were coagulase positive Staphylococcus aureus and 20 were Coagulase negative Staphylococci (CoNS). 14 Staphylococcus aureus out of 16 were methicillin sensitive and 2 were methicillin resistant Staphylococcus aureus (MRSA). Out of 16 Staphylococcus aureus, 1 isolate showed Inducible Clindamycin Resistance (iMLSB phenotype) and 6 isolates showed complete resistance to erythromycin and clindamycin (constitutive MLSB phenotype). 1 Staphylococcus aureus which was Inducible Clindamycin Resistance (iMLSB phenotype) was also methicillin resistant. 展开更多

Introduction: Health care associated infections (HAIs) are likely to be the most common complication of hospital care. World Health Organization (WHO) estimates these infections to occur among 7% - 12% of the hospitalized patients globally, with more than 1.4 million people suffering from infectious complications acquired in the hospital at any time. Keeping this in mind, the present study was conducted to delineate the level of knowledge, attitudes, and practices (KAP) for the use of proper disinfection procedures among the final year undergraduate medical students in a tertiary care hospital and teaching institute. Methodology: Present study was conducted at Government Medical College, Surat, a tertiary care hospital and teaching institute. The participants who gave consent were provided with a pre-tested questionnaire that included several questions on knowledge attitude and practices on hospital acquired infections and its control practices. Analysis of the answers was done based on KAP score. Result: 80 students who consented were included in the study. 75% of the study population had correct knowledge about the most common health care associated infections (HAIs), being infection of venous access, urinary tract infection, respiratory infections and surgical site infections, based on their current knowledge on hospital acquired infections. Majority of study participants agreed with the fact that the inappropriate application of disinfection procedures increases the risk for a health care worker of either acquiring or transmitting a HAI from/to a patient. >90% participants had a good attitude towards risk of getting or transmitting any infectious disease by a Health care worker (HCW) while working and the utility of the application of disinfection procedures during work would reduce the rates of HAI. Practices of the students towards disinfection during performance of certain medical procedures ranged from 10% to 88% of the times showing poor practices of the medical students in following disinfection practices. Conclusion: In the present study the knowledge of medical students for the most common cause of hospital acquired infection was satisfactory. The overall attitude of the students was satisfactory as the mean score was 8. The practices of the students for the application of disinfection during performance of certain medical procedures were also satisfactory, although time to time training and tutorials of these students can help in increasing their knowledge, attitude and practices. 展开更多

To get more insight into using self-assessment in writing instruction, the present study intends to explore the effects of student self-assessment on students' EFL writing by adopting writing assignments, analytic scoring rubric, questionnaires and interviews. It is found that students are able to make judgments about the overall quality of their writing in a manner consistent with those made by the teacher and students made significant improvements in content, organization, and mechanics of their writing after the practice of self-assessment while qualities concerning vocabulary and language use have been improved but not to a significant level. Moreover, the study demonstrates that the practice of self-assessment has exerted positive influence on students' perceptions of their writing skills in terms of organization, language use and mechanics while it does not result in any change of students' perceptions of their writing skills in content and vocabulary. These implications are conductive to working out a set of new models of the teaching of writing and helping further intensify the innovations of Chinese foreign language teaching. 展开更多

It investigates the relationship between language learning strategy and the CET-6 scores of students majoring in English as a foreign language(EFL). Participants consists of a volunteer pool of 45 second-year English major students at Tianjin Polytechnic University. A revised version 7.0 of Oxford's(1990, pg. 293-300) Strategy Inventory for Language Learning(SILL)and the CET-6 are administered as measures of learning strategy and the CET-6 scores. An analysis of ANOVA and Multiple Correlation is conducted to examine the relationships among six types of learning strategies and scores of CET-6. Results of this analysis reveals that metacognitive strategies and affective strategies are two major language learning strategies that preferred by the participants in the English learning process. While metacognitive strategies and affective strategies preferred by the participants do not have a statistically significant correlation with the scores of CET-6. It is the memory strategies and social strategies that have a significant correlation with the scores of CET-6. 展开更多
