    Objective: To determine the perception of medical students towards mentor-mentee system in Faculty of Medicine and Health Sciences of UNIMAS. Method: It was a cross-sectional study involving all 104 second year and 80 fifth year medical students. A self-administered questionnaire consisting of socio-demographic details, general perceptions on mentor-mentee system, academic support, personal development, and emotional and psychological support was distributed. The data was analysed using the SPSS version 19. Result: Majority of the subjects had a positive outlook towards the mentor-mentee system with a range of 45.6% to 57%. Three of the top rated perceptions were ‘mentor analyses mentee’s examination results and provides constructive feedback’, ‘mentor advises how to improve academic performance’, and ‘mentor gives encouragement and support for the challenges faced’ (66.8%, 68.0% and 62.9% respectively). Pre-cinical medical students had significantly better perception on mentor-mentee system than clinical students (p≤0.002) while those with non-clinician mentors significantly had better perceptions than those with clinician mentors (p≤0.003) on the system. No significant difference was found between the perceptions of males and females for all components (p=0.234 to 0.722). Conclusion: The mentor-mentee system was found to be successful as more than half of the respondents had posititve perception on the system and its aspects. However, pre-clinical students benefited more compared to clinical students, which reflects the need to look at the support given to clinical students. It was recommended that future studies should incorporate the perceptions of mentors.

    Statistics plays a vital role in various spheres of life. Choosing the right statistical analysis is one of the most crucial aspects in statistics. Some researchers especially those who have minimal statistical background, are often having difficulties in choosing the right statistical analysis for their study. Inappropriate analysis may produce misleading results at the end of the study. Hence, mySTATS Tracker was created as an alternative tool to assist the researcher in determining the right statistical analysis. The aim of this study was to gauge the effectiveness of using mySTATS Tracker in identifying the most appropriate statistical analysis based on the supplied input. In addition, this study intended to determine whether there was significant difference in score based on gender and faculties. The difference in the perception towards the usefulness and effectiveness of this application based on faculties was also investigated. A sample of 55 undergraduate students with various background have participated in this study. The sample of students were asked to answer a set of questions with (posttest) and without (pre-test) using mySTATS Tracker. Then, the score obtained was recorded and analysed. Gap analysis and Independent t-test were applied in achieving the objectives of the study. The results showed that there was a significant difference in scores between pre-test and post-test, p < 0.05. It could be concluded that the users scored significantly higher and answered the questions in a significantly shorter time using mySTATS Tracker compared to without using it. The study also found that there was a significant difference in score based on gender and faculties, p < 0.05. Furthermore, there was a significant difference in the perception of the usefulness and effectiveness of this application based on respective faculties. In overall, mySTATS Tracker has received a positive feedback from the potential users. This study has proven that mySTATS Tracker is a good alternative solution in suggesting the right statistical analysis to the users

    This paper discusses the multilevel approach in constructing a model for estimating hierarchically structured data of students' performance. Multilevel models that take into account variation from the clustering of data in different levels are compared to regression models using least squares method. This study also estimates the contributions of gender and ethnic factors on students' performance. Performance data of866 students in a science faculty in an institution of higher learning is obtained and analyzed. This data is hierarchically structured with two levels, namely students and departments. Analysis findings show different parameter estimates for both models. Also, the multilevel model which incorporates variability from different levels and predictors from higher levels is found to provide a better fit for model explaining students' performance.
    [Rencana ini membincangkan pendekatan multitahap dalam pembinaan model penganggaran pencapaian pelajar yang mempunyai struktur data hierarki. Model multitahap yang mengambil kira variasi data yang berpunca dari pengelompokan data pada tahap-tahap yang berbeza dibandingkan dengan model regresi linear yang menggunakan kaedah kuasa dua terkecil. Seterusnya kajian ini menganggar sumbangan faktor jantina dan etnik ke atas pencapaian pelajar. Data pencapaian akademik seramai 866 pelajar fakulti sains di sebuah institusi pengajian tinggi telah diperoleh dan dianalisis. Data pelajar ini berstruktur hierarki dengan dua tahap, iaitu pelajar dan jabatan. Hasil kajian menunjukkan kedua-dua kaedah memberikan penganggaran yang berbeza. Malah, didapati model multitahap yang memasukkan variasi dari tahap-tahap berlainan dan pembolehubah peramal dari tahap yang lebih tinggi memberikan padanan model lebih baik bagi menerangkan pencapaian pelajar].

    OBJECTIVES: The aims of this study were to identify the attitude of peer tutors (PTs) toward peer-assisted learning (PAL) and to explore the perceived benefits of PAL by PTs and peer learners (PLs).

    DESIGN: A qualitative and quantitative research study.

    METHODS: This study involved fourth-year medical undergraduates during their clinical posting in ophthalmology. One PAL session was conducted in each of the 4-week clinical postings. Peer tutors were selected during the first week and were briefed on PAL. Premultiple and postmultiple choice questions were distributed to PLs before and after each PAL session. One focus group discussion was conducted with PLs to explore their perception. Peer tutors were requested to give feedback in the form of structured Likert scale statements with 2 open-ended questions.

    RESULTS: A total of 104 students, 6 PTs and 98 PLs, participated in this study. Both tutor and learner groups expressed positive attitudes toward PAL. Peer learners preferred having PAL in a clinical setting. There were some issues related with PAL that emerged from both groups. Success in PAL depends on the teaching ability of PTs.

    CONCLUSIONS: Students have positive perceptions toward PAL. Most of the students believed PAL was beneficial to them.

    Introduction: Peer mentoring is one of the mentoring essential components in any higher institution of learning. In the Medical Faculty of Universiti Malaysia Sarawak (UNIMAS), this mentoring system has existed long but has not undergone any formal evaluation. Objective: The main objective of this study is to determine the perception of peer mentoring among medical students of Faculty of Medicine and Health Sciences (FMHS), UNIMAS. Method: It was a cross-sectional study using self-administered questionnaire. All medical undergraduate students of FMHS were recruited. Data was analyzed using SPSS version 22. Result: A total of 234 respondents participated in this study. Peer mentoring system was preferred against other mentoring system. Majority of the respondents reported that academic gain was the main benefits they gained from peer mentoring system. Negative attitude of the mentee and poor time management for the meeting were the top two worst experience encountered by both mentors and mentees respectively. More than half of the mentor and mentee perceived that peer mentoring system was beneficial to them compared to other systems, with reason that the interaction between student themselves were more easier and comfortable. Nevertheless, there should be more interaction between the mentors and mentees. Conclusion: The findings indicated there is a positive contribution of peer mentoring towards the mentoring system of the faculty. There is a need to relook at the current mentoring system and consider peer mentoring to improve the student support.

    Objectives: To assess pattern of toothpaste usage among young children under 6 years old.

    Materials and methods: This was a cross-sectional descriptive study carried out at the Faculty of Dentistry, Universiti Kebangsaan Malaysia. Parents of children below 6 years old were involved. 200 questionnaires were distributed and 136 (68%) were returned for analysis. The questionnaire covered the following parameters: type, frequency, and quantity of toothpaste usage among children, level of parental knowledge of fluoride concentration in toothpaste and selection criteria of suitable toothpaste for their children.

    Results: Majority of the respondents (83.1%) said they used children’s toothpaste to brush their child’s teeth and 62.5 % of them knew that the toothpaste used had fluoride in it. Slightly more than half of the respondents (53.7%) said they started brushing their child’s teeth one year after eruption of the first tooth. Almost an equal proportion of the respondents reported using toothpaste twice daily (50.7%) and only 44.1% of them supervised their children’s brushing. Respondents generally used more than a pea-sized toothpaste quantity (53.6%). Taste, fluoride concentration and brand of the toothpaste appeared to be the main criteria that influenced the selection of the toothpaste (55.9%). Income and educational levels of the respondents did not influence the type of toothpaste used.

    Conclusion: These findings indicated that although parents were brushing their childrens’ teeth with children toothpaste, they were still unaware of the proper usage and importance of fluoridated toothpaste.

    Introduction: Nursing is a regulated profession. Hence, the global commitment for nurses to maintain standards of practice is vital to deliver safe and competent care. Written policies will eliminate uncertainty, ambiguity, and legal issues. For this study, it focused on the importance of the nursing students to understand and practice the regulation on patient’s confidentiality in healthcare setting with the usage of technology such as social media. There is a case like nursing student infringe the privacy of patients with the information they posted on social media, such as posting a patient’s photos or videos without valid consent. Methods: This study is a quantitative, cross-sectional survey de- sign. The respondents were selected as convenience sampling of 120 nursing students from the Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah (FMHS, UMS). Results: There are 7.4% nursing students intention- ally posted in social media, 18.0% maybe and 73.8% unintentionally. And for their guilty feeling after committing confidentially policy breach on patient, there are 8.2% said NO, 32.8% said MAYBE and 59% said YES. Overall, the nursing students are aware of the patient’s confidentiality but there is still a leakage in practicing full nursing standards and regulation. Further study recommended to explore more on this issue. Conclusion: As a conclusion, this study is relevant to conduct among the nursing students to gain their understanding regarding the responsibilities as a future nurse in maintaining the patient’s confidentiality as one of the most important nursing practices to ensure quality of care and continuation of professional service of nursing profession.

    It is time to cogitate as to “how and what ”we teach in the medical faculties/schools. We are aware that the generation of students is different; called the “Z”-generation. So, in keeping with the trends in the field of globalization, IR 4.0, artificial intelligence and the techno era, there is a need to change and become flexible to meet the demands of the artificial intelligence and the era. The future generations will be the Centennials who will adapt heutagogy (pronounced as: hyoo-tuh-goh-jee) principles to learn what they are passionate about. Heutagogy was first defined by Hase and Kenyon (2000) as a form of “self-determined learning”. So, in other words, pedagogy (the art and science of teaching children) and andragogy (the art and science of teaching adults) periods are almost over or take a back seat. In simpler terms, pedagogy is faculty-centred education; andragogy is student-centred education is not enough1. Heutagogy is self-directed, transformative and the present thing2. We need to be aware and cognizant of this fact in order to cater to our clients of the next generation.

    An inventory of orchid species diversity was carried out in cloud forest of Genting Highlands, which is one of the most developed highland areas in Peninsular Malaysia. Since 1967, construction of roads and hotel complexes has had a serious impact on its physical environment and vegetation. Habitat destructions together with climate change might have caused some orchid species to be extirpated locally or extinct. The cloud forest of Genting Highlands consists of four major peaks, Gunung Ulu Kali, Gunung Chin Chin, Gunung Lari Tembakau and Gunung Mengkuang. However, not much study on orchid diversity was conducted in these areas, therefore, this study is timely and essential to evaluate the current orchid diversity after a gap of three decades. Combined findings from the current study, previous published works and specimens deposited in local herbaria, including those at the Universiti Malaya, Universiti Kebangsaan Malaysia, Forest Researh Institute of Malaysia and Biology Department, Faculty of Science, Universiti Putra Malaysia and Singapore Botanic Gardens, an updated list of orchid species found in the cloud forests of Genting Highlands is presented. A total of 134 orchid taxa were recorded, comprised of 51 genera, 132 species, 1 subspecies and 2 varieties, of which 46 are new records to Genting Highlands. Hymenorchis javanica, a species previously reported as endemic to West Jawa was recently discovered in Gunung Ulu Kali. Thirty-three species discovered during this study are currently classified as endemic to Peninsular Malaysia, of which 20 are endemic to Pahang, Perak and Selangor and a very narrowly endemic species; Corybas villosus to Gunung Ulu Kali. Through our observations, most of the orchid species in Gunung Ulu Kali are very susceptible to disappearance due to loss of habitat and local climate change. An assessment of conservation status according to IUCN criterion revealed that 47 orchid taxa from Gunung Ulu Kali were threatened with extinction. Conservation actions were suggested to conserve the orchid diversity in the cloud forest areas of Genting Highlands.

    Objectives: To assess oral health related quality of life (OHRQoL) among orthodontic patients who had been allocated into three methods of orthodontic anchorage; transpalatal arch (TPA), modified TPA-Nance (TPA-Nance) and mini-implant (MI). Materials and Methods: This study was conducted in Faculty of Dentistry, Universiti Teknologi MARA, Sungai Buloh and Puncak Perdana campus. Thirty-six orthodontic patients with anchorage requirement between 18 and 30 years old were recruited. The subjects were equally divided into three groups, which included 28 females and 8 males. The assessment of patients’ oral health related quality of life (OHRQoL) towards the anchorage supplementation using modified oral health impact profile (S-OHIP-14) questionnaires were carried out. The questionnaire was given at two time points, which was before the insertion of the allocated anchorage regime (T0) and after a week of insertion of the allocated anchorage regime (T1). Results: There was no statistical significant difference on functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability and handicap domains of OHIP-14 questionnaire between the three anchorage groups (p>0.05). Conclusion: The OHRQoL patterns, during the treatment with the anchorage reinforcement were very similar. This suggests that TPA, TPA-Nance and MI do not affect patients’ OHRQoL. The OHRQoL trends observed during the study can be communicated to patients and used to increase patients’ compliance since they are made aware of the whole treatment process.

    The use of technology in teaching and learning is increasingly synonymous with the existence of multiple online platforms. Online teaching and learning guides help lecturers and students to obtain a variety of information related to their specialization in the field of study. As all UiTM students at the Diploma level are required to take and pass the Entrepreneurial Basic course (ENT300), they need to produce an entrepreneurial project as one of the course evaluation components. However, the number of science and technology based entrepreneurship projects and products are still too few based on project titles every semester. The ENT300 Kiosk Science and Technology (KENTS) was developed specifically as a guide for the students of the Faculty of Computer Science and Mathematics and has been improved by expanding its scope to the students of the Faculty of Engineering and Faculty of Science at UiTM Johor. A more global scope in KENTS provides specialized online guides for lecturers and students in the science and technology clusters. KENTS is a platform that can be used to realize the direction of higher education in Malaysia and to assist UiTM in producing holistic graduates with entrepreneurship. This online guide platform provides teaching and learning assistance through the custom business template which is categorized into two, system development and machine design. KENTS provides a search function from a list of compilations of science-based and entrepreneurial projects that help lecturers and students find entrepreneurial ideas. KENTS database is used to store student entrepreneurial project information as an e-learning platform that can be shared by lecturers and students globally.

    The prevalence of occupational stress among academician is increasing in developed and developing countries. The job is not only to teach, but also involve in doing research, publications, consultation and administrative work. This study aims to assess the prevalence of occupational stress among academic staff in a research university and to investigate the association and correlation between stress and job factors which are career development, research, teaching and interpersonal relationship. One research university in Malaysia was selected randomly. A cross-sectional study was conducted and the respondents were recruited by using a randomized stratified sampling method. A total of 380 self-administered and validated Depression, Anxiety and Stress Scale-21 (DASS-21) and Stress Sources Questionnaires (SSQ) were distributed among academic staff between March to May 2012. The statistical analyses used were χ2, independent–t test and Pearson Correlation. Response rate was 81.1%. Stress prevalence was 22.1%. All socio-demographic factors showed no association with stress except ethnic group. Teaching, research and career development had significant association with stress among academic staff (p<0.05). Overall result showed career development, that include university condition and required publications for promotion were the greatest source of stress among the academicians. Occupational stress showed positive linear relationship to career development, research and teaching. There was a fair positive relationship between occupational stress and career development, research and teaching. It is recommended to organize continuous stress assessment program to identify and evaluate the current level of stress at the university level. This data could be a foundation for implementing prevention and control measures to reduce stress in the workplace.

    STATEMENT OF PROBLEM: Resin-bonded fixed partial dental prostheses (RBFPDPs) cemented at an increased occlusal vertical dimension (OVD) (the Dahl concept) to create space for a metal retainer remain controversial because of the lack of reported clinical studies. This study evaluated RBFPDPs by applying the Dahl concept.

    PURPOSE: The purpose of this retrospective study was to investigate the clinical factors affecting the occlusal re-establishment and short-term complications of RBFPDPs cemented at an increased OVD.

    MATERIAL AND METHODS: Occlusal re-establishment and clinical complications were reviewed in 109 participants (155 RBFPDPs) treated at the Faculty of Dentistry, Universiti Teknologi MARA from January 2013 to May 2018. Types of complications and risk factors were assessed from clinical data. Demographic factors, clinical factors, and prosthesis factors were distinguished and their association with occlusal re-establishment analyzed by using multiple regression analysis.

    RESULTS: A total of 155 RBFPDPs (42 anterior, 113 posterior) were placed in 109 participants. All achieved occlusal re-establishment, 89.9% complete occlusal re-establishment and 10.1% partial occlusal re-establishment, a minimum of 4 months after the RBFPDPs had been placed at an increased OVD. The design of the metal retainer coverage was found to be a significant factor affecting occlusal re-establishment and decementation (P

    STATEMENT OF PROBLEM: Space creation for a metal retainer of the resin-bonded fixed partial dental prostheses (RBFPDPs) with the Dahl concept remains controversial because of the lack of clinical studies.

    PURPOSE: The purpose of this clinical study was to investigate the occlusal force and occlusal contact reestablishment of RBFPDPs cemented at an increased occlusal vertical dimension (the Dahl concept) and to evaluate the factors affecting them.

    MATERIAL AND METHODS: A prospective clinical study was carried out on 28 participants receiving cantilevered RBFPDPs at an increased occlusal vertical dimension at the Faculty of Dentistry, University Teknologi MARA. Maximum occlusal forces were recorded at precementation, postcementation, and 12-week review visit by using pressure indicating film, while occlusal contact reestablishment was assessed at the precementation stage and 12-week review visit by using shim stock foils. The Wilcoxon signed-rank and chi-squared tests were used for statistical analysis (α=.05).

    RESULTS: Significant differences were found for maximum occlusal force between the precementation and the postcementation and between the postcementation and the 12-week review of RBFPDPs (P.05).

    CONCLUSIONS: Overall, occlusal force was reestablished after 12 weeks, and occlusal contact was completely reestablished in most participants after placement of RBFPDPs at an increased occlusal vertical dimension.

    BACKGROUND: The COVID-19 pandemic has caused extraordinary disruptions to education systems globally, forcing a rapid switch from conventional to online education. Although some qualitative studies have been carried out exploring the online education experiences of nursing students and faculty members during the COVID-19 pandemic, to our knowledge, no study has used the Photovoice approach.

    OBJECTIVES: To explore the experiences of nursing students and faculty members as related to online education during the COVID-19 pandemic.

    DESIGN: A descriptive qualitative design using Photovoice was adopted.

    SETTING: The study took place across five countries and one city in Southeast Asia (Indonesia, Malaysia, the Philippines, Thailand, Vietnam, and Hong Kong).

    PARTICIPANTS: Fifty-two nursing students and twenty-eight nursing faculty members who participated in online education during the COVID-19 pandemic.

    METHODS: Each participant submitted one photo substantiated with written reflections. Data were analysed using thematic analysis. Ethical approval was obtained from institution-specific ethics boards.

    RESULTS: Three themes and eleven sub-themes emerged from the data. The three main themes were: 1) Psychological roadblocks to online education; 2) Developing resilience despite adversities; and 3) Online education: What worked and what did not.

    CONCLUSION: Through Photovoice, the reflections revealed that nursing students and faculty members were generally overwhelmed with the online education experience. At the same time, participants were satisfied with the flexibility and convenience, opportunities for professional and personal development and safety afforded by online education. However, concerns over academic integrity, practical skills and clinical competencies, engagement and participation, the duality of technology and social isolation out-shadowed the advantages. It is worthwhile to explore the concerns raised to enhance online education across the nursing curriculum.

    Age estimation is one of the major components of forensic identification. Cranial suture closure has long been used as indicator for age estimation. Maxillary sutures have been less studied for estimation of age at death because they vary in their timing of closure with age. The purpose of this study was to estimate age by examining 190 Thai skulls with age ranging between 15-93 years from Forensic Osteology Research Center, Faculty of Medicine, and Chiang Mai University. Four parts of maxillary suture (incisive, anterior, transverse, and posterior sutures) were investigated the suture obliteration of each suture by computerizing from photograph. The suture were measured by pixel counting.The prediction model which based on the support vector machine (SVM) for regression or support vector regression (SVR) was utilized for data analysis. The results showed high correlation (R2 = 0.9086) between the predicted age and actual age. Plot between actual age group and predicted age in seven groups also revealed high correlation (R2 = 0.9434). These can be implied that we are able to use this SVR model to predict age at death using maxillary suture information.The interesting issue is to further apply this model in more cases to ensure the generalization of the finding. This study is the first attempt to estimate age at death using a new method based on novel analysis which considers a characteristic of relationship between maxillary suture closures with age that are not in linear form. The present study may contribute as a basis knowledge and method for further study of age estimation in archaeological and forensic anthropological contexts, especially when only skull or base of skull are found.
