The effect of surgical removal of impacted third molars on the periodontal
parameters of adjacent second molar revealed inconsistent results. Some authors suggested
improvement of periodontal parameters distal to second molar, whilst others demonstrated loss of
attachment and reduction of alveolar bone height. This study was conducted to evaluate the
alveolar bone height (ABH) and periodontal status of second molar after the surgery. (Copied from article).
Recurrent oral ulcer is a chronic inflammatory condition characterized by mucosa
ulceration, which was believed to have bacterial etiology. Streptococcus mutans is one of the
bacteria which have been implicated in this case; it is gram-positive bacteria that reside in the
biofilms on the tooth surfaces. The aim of this study was to evaluate Streptococcus mutans content
in saliva of recurrent oral ulcer patients and its role as a prognostic factor. (Copied from article).
The utilization of parallelogram structure in a small-sized humanoid robot consists of two parallel platforms that are linked serially in each leg. The thigh and shank of each leg consists of two servomotors as actuator and linked in parallel platform. By using parallel mechanism in leg structure, foot sole surface is always parallel to the walking surface at any point. Even it looks unnatural to human-like walking motion, the expected result is the robot can maintain it posture while walking and at the point foot sole touch the walking surface, unnecessary vibrates can be modulated at the certain level to remain its balance. The effectiveness and the performance of the proposed parallel platforms are experimented by using zero moment point (ZMP) method by taking various scenario data from pressure sensors attached at the footsole. Planned walking gait is introduced to be identical in terms of foot steps length and width of each leg swing. As the results, in terms of load in each actuator, required torque at servomotors can be reduced because two servomotors are used simultaneously in one parallel system. Stable walking gait can be predicted as the quantity of error falls within the error ranges from the published walking gait patterns.
This paper presents an auto grasping algorithm of a proposed robotic gripper. The purpose is to enhance the grasping mechanism of the gripper. Earlier studies have introduced various methods to enhance the grasping mechanism, but most of the works have not looked at the weight measurement method. Thus, with this algorithm, the weight of the object is calculated based on modified Wheatstone Bridge Circuit (WBC) which is controlled by programmable interface controller (PIC) method. Having this approach introduces and improves the grasping mechanism through an auto grasping algorithm. Experimental results show that an auto grasping algorithm based on pressure sensor measurements leads to a more precise grasping measurement and consequently enhance the sensitivity measurement as well as accurate movement calibration. Furthermore, several different grasping objects based on the proposed method are examined to demonstrate the performance and robustness of our approach.
The purpose of this study is threefold, that is, to examine discrete emotion and how it could contribute to the crossover phenomena in organizations, to examine how crossover affect employees’ burnout and engagement, to develop a theoretical framework of discrete emotion as mediator and its crossover in the relationship between job demand, resource and employees’ wellbeing. This paper examined past studies from Proquest, SAGE, Springer, JStor and Emerald online Database that are related to discrete emotion, spillover-crossover model, burnout and engagement. Fifty papers were reviewed from the online databases within the year 2004 to 2015. Findings show that discrete emotion has some effect on employees’ wellbeing through crossover phenomena process. Positive emotions, such as, joy and happiness can accelerate a person’s recovery from the physiological effects of negative emotions. Employees react to the antecedent and possess a discrete emotion. Employees’ discrete emotion makes crossover towards colleagues and triggers the intensity of their psychological state (engage, burnout). Practical intervention for human resource development professionals were suggested to assist employees and organizations on making it known about knowledge on discrete emotion and how it can affect employees’ wellbeing. This research produces a theoretical concept to examine the predictive potential of discrete emotion that leads to crossover phenomena in determining employees’ burnout and engagement.
Total knee arthroplasty represents a major advance in the treatment of
degenerative joint disease. It provides excellent restoration of joint function and pain
relief. The primary indication for total knee arthroplasty is to relieve pain caused by
severe arthritis, with or without significant deformity. This study is to assess
psychological impact pre and post arthroplasty. (Copied from article).
This research investigated the wear properties of Carbon Nanotube (CNT) filled epoxy polymer and fiber reinforced composites. The CNT/epoxy composites with 0.5 wt% and 1.0 wt% CNT contents were mixed at 50°C for 1 hour at a speed of 400 rpm using mechanical mixer, while woven glass fiber reinforced polymer (GFRP) nanocomposites were fabricated using vacuum bagging technique. The effect of CNT on wear properties was evaluated using dry sliding abrasion wear test that used vitrified bonded silicon carbide as abrasive wheels. The mass loss and specific wear rate curves show that wear properties of epoxy polymer and GFRP composite systems were enhanced when CNT was added. Epoxy polymer and GFRP nanocomposites showed the highest wear resistance when CNT content was 1.0 wt% and 0.5 wt% respectively. The CNT-filled composite showed improvement till up to 78.9 % from its pure system. This suggested that the load transferability between CNT and epoxy was more effective in nanomodified systems than in its pure systems. Therefore, adding CNT improves the wear properties of epoxy polymer and woven GFRP composite.
The design and build concept has become a popular contract system. It requires the owner and contractor to identify, analyse and manage risks and search for the best solutions to improve performance. The objective of this paper is to identify the project manager’s perception of risk factors associated with the design and build project in Malaysia. A total of 100 usable questionnaires were received and analysed using mean ranking and factor analysis. The results show that three most risky factors are: “client financial capability”, “inadequate cash flow by contractor”, and “lack of payment (delayed progress payment by owner to the contractor)”. Risk can be grouped into 12 categories, namely: (1) lack of management competency; (2) lack of contractor experience; (3) political issues; (4) lack of standardized system; (5) unpredictable issues; (6) lack of client experience; (7) safety issues; (8) lack of teamwork; (9) poor supervision by client; (10) lack of client information; (11) material availability; and (12) design error.
Seismic surface waves are a non-destructive technique used to obtain the dynamic properties of soil by measuring the shear wave velocity and calculating the shear modulus of soil. The shear modulus is one of the parameters to measure the stiffness of materials. This study evaluates soil profiles and the position of the sensor while conducting measurements of two , soil profiles, i.e. lateral and vertical non-homogeneities, using a continuous surface wave analysis (CSW) and multi-channel analysis of surface waves (MASW). Results showed the dispersive curve demonstrated an increased shear wave velocity with increasing depth for the sensor pair measurements on the clay (between columns), and decreased shear wave velocity with increasing depth for the sensor pair measurements on the column. In both instances the surface wave velocity results influenced by the depth and size of the wavelength, indicating that depth and wavelength controlled the volume of measurement in an elliptical shape. Therefore, the shear wave velocities and thus stiffness measured from the surface wave velocity techniques are represented the volume of soil measured across the sensor length.
Perceived work environment could be described as the opinions and attitudes of workers towards their work condition. Elements of perceived work environment such as physical environment, supportive work environment, and perceived work tasks may possibly be important factors that influence the occurrence of accidents. The objective of this study is to examine the relationship between perceived work environment and the occurrence of accidents within an electronic manufacturing industry in Kuching, Sarawak. A cross-sectional survey utilizing a bilingual self-report questionnaire was conducted to garner data from 50 workers. Independent t-test and Pearson moment correlation were used to assess data. The results indicated that the occurrence of accidents was not affected by age group. Although physical environment and perceived work tasks did not demonstrate significant relationships with the occurrence of accidents, supportive work environment exhibited a significant inverse relationship, thereby indicating that accidents could be lowered in the presence of higher supportive work environment. Thus, support and help from co-workers are essential determinants of safety at the workplace.
Glaucoma is a chronic disease that could affect the quality of life and is a potential stressor for patients. Visual field assessment is important in monitoring disease progression among glaucoma patients. Stress could influence the performance of patients in visual field test that may affect the reliability of the test. Our objective in this study was to determine the association between stress score using Depression, Anxiety and Stress Scale (DASS) questionnaire and reliability indices of Humphrey visual field analysis (HFA). A total of 155 primary and secondary glaucoma patients were recruited in the study. Face to face interview using stress component of DASS questionnaire was conducted after automated HFA test. Reliability indices; i.e. fixation loss, false positive, and false negative error, were used to determine the accuracy of HFA result. Only 12 patients (7.7%) were found to have elevated stress score. No significant correlation was found between DASS stress score and the reliability indices of HFA. There was 0.2 folds (95% confidence interval (CI) [-2.35, -0.06], p = 0.039) reduction of fixation loss for every number of HFA done. For every one year increase in age, there was 0.2 folds (95% CI [-0.38, -0.07], p = 0.006) reduction in false positive error in HFA.
Minimal stress may not affect the reliability of HFA assessment. Minimising stress among glaucoma patients is important not only for assessment of visual field but also for improvement of quality of life.
NiTi is well known for its shape memory effect and super elasticity (SE), and is widely used in medical, dentistry and aerospace applications. For shape memory, NiTi has the ability to undergo deformation at certain temperature then recover to its original shape while SE occurs at narrow temperature range just above its transformation temperature. It shows that this material remembers its original shape and is elastic under stress. The application of nitinol as partial replacement in reinforced concrete beam for seismic resistant structures is popular due to it re-centring capability and distinctive properties. Using Shape Memory Alloy (SMA) in structures has its downsides. Hence, hybrid reinforced concrete beam with SMA was introduced to improve the structure’s ductility and energy dissipation. Hence, this research is aimed at distinguishing microstructure and mechanical properties of SMA and steel rebar. Not much is known about how SMA behaves when subjected to compression. Therefore, X-Ray Diffraction (XRD) was used to analyse if any secondary phase exists and Differential Scanning Calorimetry (DSC) test was used to analyse the phase transformation. The results showed hybrid NiTi-steel rebar can address some deficiencies of NiTi and in terms of costs. On the other hand, combining them will result in super elastic recovery, displacement ductility and strength capacity for seismic resistant design.
The past decade has seen a growing recognition internationally that children have a right
to participate in matters that affect their lives. In a family legal proceeding, it is in practice left to the
discretion of a judge to decide whether the child is heard. Interviews have become the most common
approach by family court judges in Malaysia to resolve problematic custody disputes. However, many
family law practitioners believe that this can be detrimental to the children as the judges are not experts
in child psychology and counselling. Hence, this article intends to critique the effectiveness of Sulh
(mediation) procedure in resolving custody dispute (hadhanah) in the Syariah Court. Despite the
importance of consulting the affected children, their views are rarely sought nor acknowledged within
the judicial setting. Legal fraternity and parents play a significant influence on whether children’s are
heard in court and Sulh chamber. There is a need for further research to explore legal professionals’ and parents’ perspectives on children’s active involvement in decision-making. This information could
be used to develop guidelines that will assist professionals and parent in facilitating and supporting
children’s participation.
In the an electron-proton collider, neutral hadrons were produced in the hadronisation process that
occurred just after the electron-proton collision. The neutral hadrons were produced at interaction
point using reference energy from its centre-of-mass. In this paper, we discuss the kinematics of
particles produced from its centre-of-mass and the hadronisation process follows after such collision.
Introduction: The mainstay of treatment of depression relies on pharmacological and psychological treatments. On top of that, evidence also recognizes the vital role of spirituality for human wellness which leads to growing interest in its utilization to treat depression. However, research on spirituality among Muslims in relation to depression is relatively scarce. The aim of this study is to explore the understanding of spirituality among Muslim patients with depression, and to explore their spiritual needs.
Methods: This is a qualitative study conducted on 10 depressed Muslim patients at the UKM Medical Centre. Purposive sampling was done to ensure diversity of subjects. Individual in-depth interviews were conducted using semi-structured questionnaire guidelines. The data were transcribed verbatim and analysed using a thematic approach.
Result: Out of 10 patients, almost all of them expressed spiritual needs. Two major themes emerged in relation to the spiritual needs which are (i) religious needs; need for worship, religious knowledge and guidance, religious reminders, and (ii) existential needs; need for calmness, sensitivity and empathy, self-discipline, certainty, hope , physical help, ventilate and meaning of illness. These needs are essential for patients during the time of crisis.
Conclusion: The majority of patients expressed spiritual needs which are required during the process of recovery and this provides an opportunity to incorporate spiritual approaches in the treatment of depression. However, more studies are needed to demonstrate its scientific basis and to design an effective psycho-spiritual treatment modality so that the ‘holistic’ or ‘biopsychosocial-spiritual’ treatment can be integrated by health care professionals to those in need.

Information technology use in healthcare education has become a popular
medium of instruction. One of the medium of instruction is video assisted learning
(VAL). The use of VAL as an instructional method in the teaching and learning of emergency skills is not new. However, there are lack of studies on the perception of
using this method in learning emergency skills. This qualitative study involved four
focused discussion groups following a VAL instruction on emergency skills. A total
of 20 paramedics were divided into four groups. They were involved in a focussed
discussion after a VAL instruction session. Findings reveal that the paramedics
perceived three major themes which were categorized as : i) advantages of video
as teaching tool, ii) barrier in using video as a teaching tool; and iii) suggestions on
using video as teaching tool. The findings indicate that the paramedics perceived
VAL as a potential tool for learning emergency skills. However, they suggested the
language of instruction should be in their mother tongue for better understanding.
This implies that using English language has disadvantage in technology enhanced
learning for better understanding.
Introduction: External laryngotracheal (ELT) trauma is rarely encountered in clinical practice. In most
circumstances, this injury is overlooked by the primary attending team. Surgical management of ELT trauma
is complicated, because there is no established management approach for this potentially life-altering, high
morbidity injury. It is important for this injury to be identified early, as any delay in surgical intervention
may result in poor airway and phonatory outcomes. The aim of surgical reconstruction is to minimise the
above debilitating morbidities by restoring the main laryngeal functions as much as possible. Methods: We
reviewed the outcomes of six surgical interventions for ELT trauma at Tengku Ampuan Afzan Hospital from
June 2007 to June 2014. Clinical presentations, computed tomography (CT) scans features, intraoperative
findings, and postoperative outcomes were evaluated. Results: All patients made a good recovery in terms of
phonation except for one patient who had reduced speech function. After one year, one patient was still
dependent on a fenestrated tracheostomy. This article describes the surgical reconstruction techniques used
to achieve these positive outcomes. Stenting is helpful to aid healing and re-epithelialisation. Conclusion:
Prompt recognition and non-traumatised airway control are essential for addressing laryngotracheal trauma.
Subcutaneous emphysema is an important hallmark that should alert the attending physician to the
possibility of ELT trauma. Immediate surgical intervention using appropriate techniques can produce
favorable patient outcomes.
The emergence of highly active antiretroviral therapy (HAART) has revolutionized the prognosis of HIV-infected patients. However, the extended use of HAART is associated with a disfiguring complication termed lipodystrophy, a disorder of body fat maldistribution causing peripheral fat loss (lipoatrophy) and central fat accumulation (lipohypertrophy). Lipoatrophy commonly affects the face, legs, buttocks and arm, whilst lipohypertrophy frequently favours the abdomen, breast and dorsocervical region. To our knowledge, we present only the second documented case in the literature of a labia majora lipohypertrophy in a HIV-positive patient receiving long-term HAART. The severity of labial abnormality caused significant physical and functional morbidities. Labiaplasty with dermolipectomy of the labia majora and excisional lipectomy of the mons pubis was successfully performed. At a 6-month follow-up, patient had no recurrence with resolution of symptoms and resumption of normal activities of daily living (ADL).
The hydrological effects of climate variation and land use conversion can occur at various spatial scales, but the most important sources of these changes are at the regional or watershed scale. In addition, the managerial and technical measures are primarily implemented at local and watershed scales in order to mitigate adverse impacts of human activities on the renewable resources of the watershed. Therefore, quantitative estimation of the possible hydrological consequences of potential land use and climate changes on hydrological regime at watershed scale is of tremendous importance. This paper focuses on the impacts of climate change as well as land use change on the hydrological processes of river basin based on pertinent published literature which were precisely scrutinized. The various causes, forms, and consequences of such impacts were discussed to synthesize the key findings of literature in reputable sources and to identify gaps in the knowledge where further research is required. Results indicate that the watershed-scale studies were found as a gap in tropical regions. Also, these studies are important to facilitate the application of results to real environment. Watershed scale studies are essential to measure the extent of influences made to the hydrological conditions and understanding of causes and effects of climate variation and land use conversion on hydrological cycle and water resources.
Background: Early detection of alcohol abuse and associated risk(s) is necessary. It requires easy and reliable screening tools that are culturally
adapted to the local context.
Objectives: The aims of this study were to cross culturally adapt, test for its reliability and validity of the Malay version of Alcohol Use Disorder Identification Testing (AUDIT-M).
Methods: The cross-cultural adaptation process involved four stages: translation, synthesis, back translation and field pre-testing. The final version of AUDIT-M was pre-tested and post-tested within a 10-day interval among 37 respondents at the Tampin Health Clinic. Analysis of reliability and validity testing were done using SPSS version 21.
Results: There were 37 participants in this study. The Intra-Class Correlation (ICC) with single measures of the test-retest scores was 0.93 (Cronbach alpha = 0.97), while the internal consistency reliability yielded (Cronbach alpha=0.92). Validity testing for the Pre-test and Post-test analysis with the Pearson correlation analysis was r=0.938.
Conclusion: The translated Malay version of the AUDIT-M was found to be easy to understand and adaptable in the Malaysian context.
