An anthropometric survey of Federal University of Technology Owerri students was carried out in order to determine the anthropometric data needed for proper design of seats used in the classroom. A total of four hundred students, of different gender and level were involved in the survey and their anthropometric measurement were taken and recorded with the help of anthropometric tools. The anthropometric measurements taken were, Stature, sitting height, sitting shoulder height, Popliteal height, Hip breadth, Elbow rest height, Buttock popliteal length, Buttock knee length, Thigh clearance, Sitting eye height, Shoulder breadth and Knee height. The data obtained were analysed using SPSS, Excel and Minitab statistical packages to get the mean, standard deviation and percentiles. Comparing the dimensions of the existing furniture with the anthropometric measures obtained revealed that the existing furniture are not ergonomically suitable for the students. Using the results of the analysed anthropometric data, a model classroom seat was suggested which takes into consideration the seat height, seat depth, seat width, backrest height, armrest height and backrest angle.

Campus Activities

Garbage is one of the problems facing the Indonesian society. The production of garbage resulting from various individual activities is increasing each day. University of Ahmad Dahlan (UAD) Yogyakarta as one of the colleges in Yogyakarta has the potential to produce garbage of large amounts. Under the strategic plan of environmentally insightful campus development, garbage processing will be carried out by the institutions of University of Ahmad Dahlan and academic civitas. The average garbage produced by UAD 4 campus activities is 170 kg/day with an organic waste composition of 22.57 kg and non-organic 147.43 kg. During this time the garbage was directly distributed to the Piyungan landfill without being processed first, as the campus party had not been available garbage processing devices. The purpose of the study was to design organic garbage processing tools into compost fertilizers. The study used an ergonomic approach by utilizing anthropometric data in the determination of size from the design. Anthropometric data used in this study are Tinggi Bahu Duduk (TBD) or Shoulder High Sitting, Lebar Pinggul (LP) or Hip Width, Pantat Popliteal (PP) or Popliteal Butt, Tinggi Siku Berdiri (TSB) or Standing Elbow Height, Panjang Lengan Bawah (PLB) or Lower Arm Length, Lebar Bahu Atas (LBA) or Upper Shoulder Width, and Tinggi Lutut (TL) or Knee Height. The result of the study was an ergonomic Rotary Composter tool design operated by one person manually with dimensions 115 cm long, 148 cm wide, 115 cm tall, 60 cm barrel diameter, seat rest height 58.75 cm, 41.23 cm seat width, seat base length 45.39 cm, the distance between seats, tool height 114.94 cm, with tool 37.33 cm wide, seat rest 50 cm, 13 cm, seat width, and seat height 59.08 cm.

Background. Inappropriate design of sitting furniture and working equipment causes the serious musculoskeletal injuries and various pains as well as reducing working efficiency. Uncomfortable sitting posture in prolonged driving in Bangladesh is an issue to be solved immediately. Therefore, anthropometric databank of user population is significantly essential for the suitable dimensional design for avoiding these remarkable problems.Methods. This study analyses the anthropometric data of the Bangladeshi male vehicle driver aged between 30 and 60 years. A total of 210 Bangladeshi healthy drivers are considered for 15 anthropometric measurements and compared with the similar anthropometrics of other nationalities.Results.The mean stature and sitting height erect of Bangladeshi driver are 1645 mm and 843 mm, respectively. The mean of body mass index (BMI) of the drivers is 26.09 kg/m2, which indicates that the drivers are overweight. The mean stature of Bangladeshi driver is 17 mm shorter than the driver of Korea and 115 mm shorter than the driver of Iran.Conclusion. There are substantial differences between the body dimensions of Bangladeshi driver and similar dimensions of other countries. In comparison, Bangladeshi driver is found to be the shortest compared with the sample of other nationalities.

Field Setting

Ergonomists have long recommended user adjustable furniture for office workers. A majority of the recommendations have been based upon anthropometric models of economically “correct” postures. Research validation of these proposals is sparse, and those that have been conducted are predominantly laboratory oriented. This research observed the use of adjustable furniture in a field setting. Three questions were addressed: 1) what are the preferred settings when the equipment has been used for a length of time?; 2) do people change the settings?; and 3) how do these measures relate to anthropometric data? The offices of 91 workers were measured covertly. Twenty one offices were measured once, 41 twice, and 29 three times. All the offices had an adjustable VDT stand with independent height and angle adjustments for both the keyboard and display. Seat height had a mean and standard deviation of 20.0 and 0.85 inches. The height of the home row of the keyboard had a mean of 29.1 and a standard deviation of 1.2 inches. For the display surface the mean and standard deviation were 29.7 and 1.3 inches. In terms of repeated measures, 62.9% of the chair heights, 57.1 % of the keyboard heights, and 91.4% of the display heights did not change. Of the observed changes, 90% were between 0.25 in and 0.75 inches. None of the observed heights correlated well with stature, seated eye height, or popliteal length. One correlation was 0.32, all others were less than 0.20. The results are similar to other published data in that the measured settings are much higher than anthropometric models would predict. More significantly, they do not match the new ANSI guideline nor the proposed CSA guideline for adjustable furniture. This suggests that the ergonomic theories behind these recommendations need to be modified to more closely reflect actual use products.

Attention to the dimensions of the human body has actually existed since centuries ago. Even philosophers, artists, and architects admire the size of the human body. The design of ancient worship such as the Greek temple is the result of the design collected from the proportional measures of various members of the human body. This study aims to explore the proportion of golden section found in the human body both men and women. Methods of data collection using anthropometric data of Indonesian people. Further data is analyzed proportion using golden section. The results of this study indicate that the human-Indonesian body contained the value of Golden Section proportion is the ratio between the height of the elbow standing with height; hip height with standing eye height; tall sitting eyes with a sitting vertical range; Vertical reach sits with standing vertical range; Knee height with sitting height. The value of the proportion of the golden section contained in the human body applies to both men and women. The results of this study can be an early reference findings, that the human body contained the value of the proportion of golden section. These findings still need to be explored with further research, given the problem of the proportion of golden section associated with the numbers so it requires accuracy of measurement data.

This paper presents the differences of anthropometric data between Malaysian, Chinese, Korean, Japanese, Taiwanese, North American, North African, South Indian, Portuguese and Australian, which can be use in anthropometric test dummy (ATD) and the computational modelling of ATD. The available anthropometric data of stature, sitting height and sitting knee height for male and female are analyzed by weighting them according to their ranking in the corresponding parameters and presented in bar chart. It is found that Australian male and female have the biggest body posture compared with others. The results also indicate that females in Australia, North Africa and South India, when the three parameters are considered, they have bigger posture than male. For the computational model, hybrid modelling combine finite elements and rigid bodies can be an alternative approach.

An important role in whole performance of volleyballers plays the anthropometric parameters. Anthropometric differences mostly define the position and the role of the players in the court. The aim of this study was to determine the difference in some anthropometric parameters of young female volleyball players and young male volleyball players. This study assess 22 young boys volleyballer (17.1± 1.8 SD) and 25 young girls volleyballer (16.9 ± 1.9 SD) located in Tirana. Anthropometric measures assessed were: body-height, body-weight, body-waist circumference. Equipment used for measuring were digital scale with height rod (Health O meter professional scales) and flexible metric tape. Independent samples test and t-test were used to analyze quantitative data. Boys had the mean and SD of body-height (177.95 ± 8.351) while girls showed the mean and SD (165.52 ± 6.593). In terms of body-weight, boys were presented with mean and SD (71.9 ± 8.608) while the girls had the mean and SD (62.39 ± 10.597). Boys displayed a mean value in waist-circumference (81.18 ± 5.413) while girls showed the mean and SD of (73.79 ± 7.475). This research provided an original comparison of anthropometric measurement between boys and girls on young volleyball players where boys had larger mean of body-weight, body-height and body – waist circumference.

While studies on large samples of recreational runners have often relied on participants’ self-reported height and body mass, the validity of these data have not been investigated for this population. Hence, this study sought to examine the validity of self-reported anthropometric measures among recreational marathon runners. Female ( n = 32) and male ( n = 135) recreational marathon runners were requested to estimate their body mass and height (and we calculated their self-reported body mass index [BMI]), after which we took actual measures of their body mass and height and calculated their actual BMI. Participants’ self-reported values underestimated their actual body mass by 0.65 kg ( p < .001, η2 = 0.222) and their actual BMI by 0.35 kg ⋅ m−2 ( p < .001, η2 = 0.245). There was a significant Assessment Method × Sex Interaction for both body mass ( p = .019, η2 = 0.033) and BMI ( p = .017, η2 = 0.034), as women underestimated body mass values more than men. Participants overestimated their height by 0.44 cm ( p < .001, η2 = 0.075), but the interaction of sex and assessment method for height was not statistically significant. Underestimates of body mass correlated with marathon racing speed ( r = .24, p = .006) and body fat percentage ( r = −.29, p = .001) in men, but not in women ( p > .05). The disagreement between self-reported and measured anthropometric data in the present sample was lower than has been previously reported for the general population, suggesting that marathon runners may more accurately self-perceive and/or report their anthropometric characteristics. These findings are of practical value for health professionals and researchers (e.g., nutritionists and exercise physiologists) questionnaires to recreational marathon runners.

This study aims to determine the particulate matter (PM2.5) mass concentrations and the comfort parameters (total bacterial counts (TBC), total fungal counts (TFC), relative humidity and temperature) in a university building. The samplings were carried out in three different indoor areas, including lecture hall, laboratory and lecturer office. PM2.5 samples were collected over a period of 8 h sampling using a low volume sampler (LVS). The anemometer Model Kestrel 0855YEL was used to measure relative humidity and temperature parameters. The sampling of airborne microorganisms was conducted by using microbial sampler at 350 L air sampled volume. The results showed that the highest average of PM2.5 was at lecture hall (88.54 ± 26.21 µgm-3) followed by lecturer office (69.79 ± 19.06 µgm-3) and laboratory (47.92 ± 24.88 µgm-3). The mean of TBC and TFC readings recorded as follow; 32.71 ± 5.91 cfu m-3 and 76.71 ± 21.5 cfu m-3 for laboratory, 112.1 ± 29.06 cfu m-3 and 124.67 ± 23.35 cfu m-3 for lecturer office, 121.74 ± 19.33 cfu m-3 and 115.33 ± 8.08 cfu m-3 for lecture hall. The average of all comfort parameter was within the prescribed standard by Industry Code of Practice on Indoor Air Quality 2010 for all sampling sites. Therefore, all occupants of the building can work in a conducive and comfortable environment. This study is in line with the objectives of National Policy on the Environment (DASN), which focusing on achieving a clean, safe, healthy and productive environment for present and future generations.

Abstract Background: HAART has been reported to be associated with a number of side effects in human immunodeficiency virus patients among which dyslipidemia is a common metabolic disorder. Methods: A facility based comparative cross-sectional study among 228 HIV positive persons was conducted from July to August 2020. Socio-demographic and clinical data were collected using structured questionnaires. Fasting venous blood sample was drawn for Lipid profiles and CD4 cell determination. Anthropometric measurement was done. Data was analyzed using SPSS version 22 for windows. Result: A total of 228 HIV patients were enrolled in the study. Prevalence of dyslipidemia in HAART naive and on HAART HIV positive persons was 61(53.5%) and 84 (73.7%), respectively. The prevalence of TC≥200 mg/dl was 50% and 30%; HLD-c<40 mg/dl was 43.8% and 36%; LDL-c≥130mg/dl was 48.3% and 28.1%; and TG≥150 mg/dl 59.6% and 39% among on HAART and HAART naïve, respectively. Age greater than 40 years (AOR = 3.27, 95% C.I: 1.47 - 7.25), blood pressure ≥ 140/90 (AOR = 16.13, 95% C.I: 5.81 - 44.75), being on HAART (AOR = 2.73, 95 % C.I: 1.35 - 5.53) and body mass index > 25kg/m2 (AOR = 1.92, 95 % C.I: 1.20 - 4.81) were identified as determinants of dyslipidemia. Conclusion: The mean value of lipid profile was significantly higher among HIV positive clients on HAART as compared to those HAART naïve HIV positive clients.
