Influence of dental implant designs on stress distribution and micromotion of mandibular bone / Muhammad Saiful Islam Mohd Izra'ai
Get PDFThe significant effects of biomechanical dental implant designs have been realised by some researchers, however, the studies were restricted on the discrete invariability of designs and geometries of dental implants on the primary stability of immediately loaded implants. Moreover, restricted procedure and limited software ability to develop a comprehensive 3D model of mandibular bone make the in vitro studies on dental implants relatively unreliable. This research was conducted to provide a feasible method for reconstructing the 3D model of mandibular bone to undergo finite element analysis. This study also examines several design features of dental implants based on commercially available products. Then, the highest performance dental implant design was evaluated, and the significant design parameters were studied in order to determine the optimal combination of design parameters. Computerised Tomography scan was conducted to generate head images for bone reconstruction process. MIMICS software 8.0 and 3-matic software were used to develop the 3D mandibular model. The reconstructed mandibular model was then assembled with five different 3D models of dental implants. Feasible boundary conditions and material properties were assigned to the developed muscle areas and joints. The results of the maximum von Mises stresses, shear stresses and deformations were analysed, and the best design was selected. Next, grey based Taguchi method was used to identify several design parameters influences such as conical hollow height, thread thickness, cutting-edge angle and cutting-edge depth. The second model appeared to exhibit the highest performance in this bone remodelling prediction simulation. Lastly, the optimal combination of design parameters calculated in this study were 5 mm of conical hollow height, 0.3 mm of thread thickness, 30° of cutting-edge angle and 6 mm of cutting-edge depth. In conclusion, this research provides a systemic approach to develop segmented 3D mandibular bones with quality meshing in order to prevent error in finite element analysis. Based on this study, the suggested optimal combination had improved the dental implant and bone performance

No full textHafazan Interactive Memorization (HIM) CTU101 is a product of an interactive memorization application that able to assist students in order to complete their hafazan assessment. Fundamental of Islam course with code CTU101 is a core subject of university that compulsory to be taken by all diploma students at UiTM. In order to achieve a good carry mark, one of the assessments is to memorize 1-20 verses of Surah Yasin for acquiring 20 marks. However, students reach the difficulties to fulfil this assessment due to weak memorization the verses of the surah for several reasons; first, time restriction to complete the task, second, students’ profile not considered as a huffaz. Third, students considered this assessment as an obstacle. Upon on these issues, Hafazan Interactive Memorization (HIM) was introduced to overcome the students’ problem in memorization. Researchers have created an interactive application to test students' memorization and make it easier for them to improve memorization of surah. Based on the survey as tested, the findings indicated students able to achieve high score and managed to memorize with flying colours after using this application. The novelty of this product is i) fun games memorization, ii) enhance a new method of hafazan through HIM, iii) Easy to access and very comprehensive. The benefits of HIM are i) potential tools in monitoring students’ assessment for hafazan ii) Potential tools for assist the lecturer in assessing students’ progress in hafazan assessment, iii) it can be share, apply, adapt, and develop in others organization i.e., university, schools etc. with the same interests
History learning with TikTok (HLTT) / Syaimak Ismail, Aemy Aziz and Muhammad Saiful Islam
No full textHistory is not the favourite subject of the young generation today. History is considered an uninteresting subject and not necessary to learn. However, the subject of history remains a compulsory subject to be studied in all IPTA and IPTS in Malaysia, such as Malaysia Studies, Ethics and Civilization, and Ethnic Relations. In fact, students will not be able to graduate if they fail this subject. Accordingly, researchers look for solutions to assist students in improving their understanding of history. In this study, researchers use TikTok as a medium to teach history. The videos used are simple and easy to understand. The lecturer will share a short TikTok video that lasts 3 to 5 minutes after teaching a topic. The video includes a summary of the topic that was studied. This TikTok video's explanation assists students in better understanding history. The content of this TikTok is simple to understand due to the use of simple language, interesting writing, interesting visuals, and background music that students enjoy. This research uses a survey method to get students' answers on whether this medium of TikTok is suitable to be used to convey historical information or otherwise. The results of the study found that TikTok is a medium that is easy to understand and suitable for teaching and learning history. At the same time, through the medium of video, TikTok is able to focus on students and help them understand student content such as ethical history and civilization topics that are considered boring and uncritical. Therefore, teaching and learning through this TikTok video is able to add additional value to the delivery of lesson content and attract students to focus on the discussion topics that will be highlighted in class
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Key principles and characteristics of an Islamic brand model with special reference to Islamic brand attire
Get PDFBack in 2007, Islamic brands captivated the attention of marketing scholars. Most previous studies regarding Islamic brands adapted the conventional brand theories and models in examining Muslim consumers' behaviour towards a brand. The adaptation of the conventional brand theory is inappropriate to explain from the
Islamic point of view. Based on the call for the development of an Islamic brand, this study aimed to develop the Islamic brand model from the Islamic perspectives specifically in Islamic attire. Hence, the four objectives of this study were to: (a) explore the meaning of lslamic brand, (b) explore the characteristics of the Islamic brand,
(c) identify the characteristics of the Islamic principles in shaping the Islamic brand attire, and (d) investigate firms' current practice in the Islamic brand attire industry. A qualitative approach was employed to gather information for the study through: (a) literature review, (b) interviews [thirty four (34) Islamic experts and thirteen (13) firms], and (c) the observation method. The data analysis used the thematic analysis by applying the method of istidlal. The results demonstrate that: (a) the definition oflslamic brand should consist of three principals; aqidah, sharia, and akhlak, (b) there are three main characteristics in the Islamic brand, i.e. aqidah, sharia, and akhlak, (c) there are relationships between aqidah, sharia, and akhlak in shaping the Islamic brand, and (d) only a few firms comply with the Islamic brand core principles while the others are still based on the conventional brand value and aspiration. This research complements the conceptual contribution (new knowledge of definition, characteristics, and interaction between Islamic core
principles and Islamic brand attire) and the methodological contribution (epistemology and ontology from the Islamic perspective, and applying the method of istidlal in the thematic data analysis). Lastly, the findings can be used by Muslim and non-Muslim firms in designing the product
