Manual anthropometry takes direct measurements from the subject using sliding and spreading callipers, flexible measuring tapes and protractors. These include manual anthropometry ( 11, 12) and two-dimensional (2D) ( 5, 10, 13– 16) and 3-dimensional (3D) ( 8, 17, 18) imaging techniques.
Several methods can be used to measure facial soft tissues. Many of these studies highlight the importance of incorporating ergonomic principles into design to ensure end-products fit with the body conditions and sizes of the target users. Numerous local anthropometric studies have been undertaken to achieve various objectives for the different needs of a range of target groups such as preschool children ( 2), young adults ( 3) and older persons ( 4), and such studies include some that have focused on the facial anthropometry of the Malaysian population ( 5– 10). It is widely applied in orthodontic and reconstructive surgery, forensics, and the design of helmets, masks, eyeglasses and respirators ( 1). The results of this study also suggest that 2D photogrammetry can be used to supplement direct measurement for certain facial dimensions.Ĭraniometry is a specific component of anthropometry that focuses on the measurement of the anatomical size of the head and face of living subjects. The ICC showed head breadth had poor reliability, whilst Bland-Altman analyses showed seven out of 10 facial dimensions using 2D photogrammetry were accurate, as compared to direct measurement.Ĭonclusion: Only certain facial measurements can be reliably and accurately measured using 2D photogrammetry, thus it is important to conduct a reliability and validation study before the use of any measurement methods in anthropometric studies. There were no statistical differences in respect to the remaining eight facial dimensions, where the smallest mean difference was 0.3 mm and biggest mean difference was 1.0 mm. However, statistical differences were noted for two facial dimensions, i.e., bizygomatic breadth and bigonial breadth, and clinically the magnitude of difference was also significant. The mean measurements derived from direct measurement and 2D photogrammetry were mostly similar.
Results: Except for head breadth and bigonial breadth, which were also found to have low inter-rater reliability, there was no significant difference in the inter-rater mean value of the 2D photogrammetry.
In addition, ICC and Bland-Altman analyses were used to assess the reliability and agreement of 2D photogrammetry with direct measurement. An assessment of inter-rater reliability was performed using intra-class correlation (ICC) of the 2D images. Primary and secondary outcomes: Ten facial dimensions were measured using direct measurement and 2D photogrammetry. Participants: A subset of 96 participants aged 18 and above. This study aimed to assess inter-rater reliability of 2D photogrammetry and to examine the reliability and accuracy of 2D photogrammetry with direct measurement. Two-dimensional (2D) photogrammetry has replaced direct anthropometric method, but the reliability and accuracy of 2D photogrammetry has not been quantified. Objective: Facial anthropometric data is important for the design of respirators. 2Faculty of Medicine, Department of Social and Preventive Medicine, University of Malaya, Kuala Lumpur, Malaysia.1Environmental Health Research Centre, Institute for Medical Research, National Institutes of Health, Ministry of Health of Malaysia, Shah Alam, Malaysia.Players must undertake TWO man missions using TWO man strategies and tactics to ultimately create a TWO man advantage that no enemy can withstand.Yin Cheng Lim 1,2 *, Ameerah Su'ad Abdul Shakor 1 and Rafiza Shaharudin 1 It is the dream of the human machine.Ĭontemporary Storyline Ripped from the HeadlinesĪRMY OF TWO will captivate gamers with a politically charged storyline, centering on the impact and ethical issues of Private Military Corporations.Ĭo-op is no longer a mode, it's the game.
