Cross professional team characteristics, translation and construct validation of teamwork survey questionnaire (TSQ) at Malaysian east coast public Hospital
(2023-03)
Samsudin, Wan Siti Auni Wan
Cross professional teamwork in healthcare refers to the interaction between individuals with different expertise and training backgrounds, working together towards shared patient care goals. Cross professional teamwork is necessary to support integrated service delivery. However, cross professional teamwork has not been given sufficient attention in Malaysia’s developing country context. There is a lack of tools to assess cross professional teamwork for Malaysian settings. This study aimed to translate the English version teamwork survey questionnaire (TSQ) into Malay and perform tool construct validation at a Malaysian east coast public hospital. The TSQ assesses teamwork on domains of integration, climate and efficiency; the tool has been previously used in Swedish and Australian settings. This study’s aim was achieved through a cross-sectional mixed methods study in three phases. Phase 1 and Phase 2 were carried out through qualitative approaches while Phase 3 utilized a quantitative approach. Phase 1 focused on translating the TSQ into Malay language using forwardbackward translation together with the committee approach. Next, a qualitative interview study was conducted in Phase 2 to explore fulfillment of cross professional team characteristics at the hospital’s 16 inpatient wards. A total of 35 interviews were conducted with medical, nursing and allied health professionals; the sample is sufficient for qualitative data saturation. Recordings from interview sessions were transcribed and thematically analyzed. The construct validity and reliability of the Malay version TSQ was determined in Phase 3. In Phase 3, 150 respondents were recruited from wards found to have cross professional team characteristics during Phase 2. A response rate of 98.24% was obtained in filling in the Malay version TSQ, the percentage of recruited respondents being sufficient for statistical analysis. Construct validity was assessed through Principal Component Analysis with Varimax rotation and reliability was tested through the analysis of internal consistency. Findings from Phase 1 indicate the translated Malay version TSQ to have equivalence with the English version. Phase 2 interview findings reveal that inpatient wards generally fulfill cross professional team criteria related to team composition, patient care objectives and professional interactions. Phase 3 construct validation results indicate that three constructs namely team climate, team efficiency and team integration, without any item deletion are valid for the Malay version TSQ. The Cronbach’s alpha value is 0.917 for the translated whole TSQ scale, while the three scale constructs also have reliable Cronbach’s alpha values in the range of 0.703-0.946. Discrepancies for particular words used from the forward backward translation process were resolved without affecting meaning of the original items. Health professionals in this study acknowledge the different professions involved in patient care. However, disciplinary diversity at the respective wards varies depending on patient care specialties and treatment objectives. The Cronbach’s alpha values for the Malay version TSQ factors reflect better team climate and integration values and comparably similar team efficiency value when contrasted with the original tool. In conclusion, the results support usage of the tool as a reliable instrument for assessing cross professional teams in other similar Malaysian public healthcare services. Further research could test the reliability and validity of the Malay version TSQ in other Malaysian regions.

(2023-03)
Thanuraj, Suntharalingam
Medicine ball training has been studied to determine if it can help to improve physical performance and skills performance of basketball players. This study investigated the effects of eight weeks of medicine ball training on physical performance and basketball skill performance among male basketball players aged 18 to 24 years. 28 subjects were recruited into two groups, namely the experimental group (EG) and the control group (CG), with 14 subjects in each group (EG: mean age was 21.25 ±1.34 and CG: mean age was 20.52 ±1.77). To detect differences within and between the study groups, repeated-measures ANOVA was used. The analyses demonstrated significant pre-test, mid-test and post-test effects on physical performance. All the physical performance fitness variables examined were significant with p<0.01 and the skill performance analyses showed significant differences in all variables with p<0.01. The experimental group (EG) that received medicine ball training showed improvements in physical performance, which was expressed in the form of percentage in the following variables: Overhead Medicine Ball Throw (OHMBT) (5.11%), Standing Long Jump (SLJ) (4.52%), Sprinting 20 m (SPRINT) (1.34%), Agility T-Test (AGILITY) (3.49%), Vertical Jump (VJ) (6.45%), and Back and Leg Dynamometer (BLD) (16.40%). Moreover, this study found that the experimental group that received medicine ball training showed improvement in basketball skill performance as well, which was expressed in the form of percentage in the following measures: Control Dribble (CD) (2.14%), Defensive Movement (DM) (3.22%), Passing (PASS) (6.83%), and Speed Spot Shooting (SSS) (13.29%). This research suggests that incorporating medicine ball training into regular exercise routines can significantly increase physical performance and basketball skills. Coaches are advised to include medicine ball workouts into players' daily training regimes. The incorporation of medicine ball workouts that align with specific skill work can improve basketball skill performance. The recommended medicine ball workout program provides a useful framework for evaluating improvements in physical performance and basketball skill performance among basketball players.
A methodology building for multilayer feed-forward neural network (MLFFNN): an application in biometry modelling
(2023-04)
Adnan, Mohamad Nasarudin
This research aims to develop a hybrid method for Multi-Layer Feed-Forward Neural Network (MLFFNN) with two different approaches; (i) Multiple Logistic Regression (MLogisticR) for the first method, (ii) Multiple Linear Regression (MLinearR) for the second method. The developed hybrid method is based on bootstrap, regression, and MLFFNN. In the first method, the accuracy of the developed method is measured based on the value of the Mean Squared Error Neural Network (MSE.net), Mean Absolute Deviance (MAD), and the accuracy percentage. While for the second method, Mean Squared Error Neural Network (MSE.net) and R2 will be used to evaluate the performance of the proposed method. All those components serve as a yardstick to determine the accuracy and efficiency of the developed model. Existing software only produces limited results. The main focus of this study is the need for better decision-making with solid evidence. The main goal of this research is to build a hybrid method and generate a numerical result and visualization (graphical representation). The results from both case studies show that the hybrid method has successfully improved the accuracy, effectiveness, and efficiency of parameter estimation in the final results of the analysis. The findings of this study contribute to the development of a comprehensive research methodology in future and suggest more accurate results for the decision-making process.
Cross-cultural adaptation of the consensus auditory-perceptual evaluation of voice (cape-v) into Malay: validity and reliability study
(2023-02)
Mossadeq, Nurhayati Mohd
Auditory-perceptual rating of voice is one of the compulsory clinical voice evaluations. One tool that has gained attention for this purpose is the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). The CAPE-V has been reported to have a more standardized approach in evaluating the voice. Because of its advantages, the CAPE-V has been adapted in several languages to suit specific populations. Accordingly, the adaptation of the CAPE-V into Malay is essential for its utility among the Malaysian population, which this study aims to achieve. This crosssectional study involves translating the CAPE-V into Malay, followed by establishing the validity and reliability of the translated CAPE-V. The translation processes (i.e., forward and backward) involved 4 translators with at least 14 years of experience. Most items were similarly translated by the translators, except for a few, which were subsequently accepted as similar, following consensus among the translators. The content validity analysis involved 2 raters, with at least 12 years of clinical experience, using the CVI method. The CVI value was above the acceptable level, thus, all items were retained. For the analyses of construct validity, concurrent validity, inter-rater reliability, and intra-rater reliability, the translated CAPE-V, termed the Malay CAPEV, was used to rate the voice samples recorded from 38 participants, which consisted of 19 individuals with normal voices (6 males and 13 females) and 19 individuals with voice disorders (8 males and 11 females). The ratings were performed by 3 raters with at least 12 years of clinical experience. The construct validity was examined by using the known-group method involving a comparison of the scores of each vocal parameter of the Malay CAPE-V of the normal and disordered voice groups using the Mann- Whitney U test, which indicated a statistically significant difference between the two groups. For the concurrent validity, the relationship between the scores of each vocal parameter of the Malay CAPE-V and GRBAS Scale were examined using the Spearman correlation, which indicated a statistically significant very strong positive correlation between the two tools. For the inter-rater reliability and intra-rater reliability, the ICC values of the scores of each vocal parameter of the Malay CAPEV were all above the acceptable level. Therefore, the Malay CAPE-V is a valid and reliable tool for an auditory-perceptual rating of voice among the Malaysian population.
Effect of sintering temperature on mechanical behaviour and bioactivity of calcia-stabilized zirconia derived cockle shells bioceramic
(2023-03)
Wahab, Nur Ain Adila Abd
The original experimental research carried out for this study by previous researcher was to investigate the synthesized of calcium oxide derived from cockle shells to be used as stabilizer for zirconia bioceramic at different temperatures. However, this research was continued by improved the production of calcium oxide derived from cockle shells using an improved protocol and determine its purity. Further, the improved data analysis of Ca-SZ bioceramic at different sintering temperatures were compared to the commercialized CEREC Sirona dental block. Hence, the aim of this study is to investigate the effect of sintering temperature on structural, morphological, mechanical, and biological properties of calcia-stabilized zirconia derived cockle shells bioceramic. To achieve this objective, three sintering temperatures at 1200 oC, 1300 oC and 1400 oC were selected in order to understand the structural, morphological and mechanical properties of Ca-SZ bioceramic after incorporation of 8 wt% of nano-CaO powders derived from cockle shells. Moreover, to give better comparative results, CEREC Sirona was sintered at temperature 1510 oC followed the protocol provided by Sirona, The Dental Company. In this experimental work, the diluted cockle shells powder was mixed with calcium chloride (CaCl2) and potassium carbonate (KCO3), using mechanochemical synthesis process. Then, nano-CaCO3 powder underwent calcination process at a temperature range of 300 oC – 550 oC to obtain nano-CaO powders. Nano-CaO powder derived from cockle shells were characterized using X-Ray Diffraction (XRD) analysis, Field Emission Scanning Electron Microscopy (FESEM) and Transmission Electron Microscope (TEM) to ensure high purity of nano-CaO powder was obtained in fabricating Calcia-Stabilized Zirconia (Ca-SZ). FESEM and TEM analyses show that nano-CaCO3 produced hexagonal shape crystals while nano-CaO display spherical shape with crystal-like structure. Next, Ca-SZ bioceramic derived cockle shell powder obtained at different sintering temperature were then compacted and characterized using FESEM and XRD. Ca-SZ sintered at 1400 oC showed the highest mechanical properties and better in in-vitro test using SBF solution compared to other sintered specimens due to the pore size reduced within temperature rise. However, Ca-SZ sintered at 1400 oC produced lower mechanical strengths when compared to commercialized CEREC Sirona. Therefore, these findings revealed that by adjusting the previous protocol, improved, pure nano-CaO may be synthesized using natural Ca source from cockle shells. Additionally, the fabricated Ca- SZ has a potential in biological properties and also showed a significantly lower mechanical properties compared with CEREC Sirona when sintered at 1400 oC which may be easier for machining and has a potential to be commercialized soon which helps in study for dental treatment.
