Preface
Ergonomic and human factors engineering has a vital role to play in today’s world of fierce competition. People are looking for new ways to improve productivity. Human-centred technology and the use of humans as a scarce resource are necessities of the moment. Researchers in the past have shown that the human–machine working environment as a whole, if given proper and due consideration, can lead to the operation of the system in an efficient manner. The work done in the area so far should be compiled/reviewed to standardize procedures, so that professionals and engineers can use the significant but scattered knowledge available in the literature. Not only will this help people improve results, but it will also recognize the need to make it an essential part of the work culture. Although the knowledge and use of such practices are somewhat satisfactory in industrially developed nations, the picture is quite bleak in developing and underdeveloped countries. Cost-effective ergonomic solutions based on their physiological and anthropometric consideration are the need of the moment for subsequent countries. These can greatly help you catch up with your developed counterparts. The papers contained in this proceedings were presented at the 15th International Ergonomics Conference on Ergonomics for Improved Productivity held at Aligarh Muslim University, Aligarh, India, December 8–10, 2017, under the aegis of the Indian Society of Ergonomics. The aim of the conference was to provide a key international forum for academicians, researchers and industrial partners to exchange ideas in the field of ergonomics/human factors engineering. The outcome was the introduction of new and better ways to improve productivity by creating a better work environment that leads to a satisfying and sustainable way of life. The proceedings consists of two volumes that contain several modules of prominent research areas of ergonomics. The conference was well attended with the participation of researchers/practitioners from around the world. As there was a wide

variety of people who contributed to these procedures, we are confident that they will prove to be a valuable collection on the topic of ergonomics for improved productivity and humanizing work and work environment. Aligarh, India

Assessment of Human Cost of Work of Tribal Women Farmers in Harvesting of Maize with the Use of Improved Sickles Harshita Jain, Suman Singh, and Hemu Rathore
1 Introduction India is among the top ten countries in the world with respect to production of cereals. Among the cereal crops, India stands on 6th position with respect to production of maize (FAO STAT 2013). It is third most important cereal in the country after wheat and rice. Women constitute almost half of the work force engaged in agriculture. The rural women participate in a broad range of agricultural activities such as production, processing, preservation and utilization of food. They play a key role in the entire food system starting from the selection of seeds, sowing, manuring, drying, stacking, storing and feeding the family from the harvested produce. Tribal women constitute half of the work force among tribals in India. Rural women play key roles in agriculture sector by working with full passion in production of crops right from the soil preparation till post-harvest activities (Ahmed and Hussain 2004). Tribal women are discriminated, though they make enormous contribution to the agriculture and allied sectors. They have very little access to the knowledge and skills of modern farm technologies and related resources. The data on participation and drudgery faced by tribal women in agriculture as per existing review are very limited. Hence, the present study was undertaken to establish a database on drudgery experienced therein tribal areas. The technology intervention gave exposure to tribal women for reducing drudgery in agriculture, particularly in maize harvesting operations. In the present investigation, the human cost of work in various parameters like biomechanical and physiological was done to compare the difference between traditional and improved methods of agriculture. The present study was conducted with the objective to assessed human cost of work of tribal women farmers in harvesting of maize with the use of improved sickles. H. Jain (&) S. Singh H.

2 Methodology The present investigation was carried out in the Kherwada Tehsil of Udaipur district of the Rajasthan state, which is one of the tribal districts of the state. In selecting the district, the main consideration was the agriculture as the main occupation of people living in such villages. In this area, male migration rate is also high. Human cost of the work was calculated for 30 purposively selected women farmers who were willing to participate in identified drudgery-prone activity, i.e., harvesting performed by tribal women. Intervention with improved sickles was done on these 30 purposively selected subjects. The criteria of selection of these 30 subjects was on the basis of willingness of subjects, and normal range of BMI, blood pressure, and heart rate. The subjects having normal BMI, blood pressure, and heart rate and not suffering from any chronic disease were selected for investigation for getting reliable results. An experimentalcum-exploratory research design was used for this study as the study was concerned to find out the psycho-physiological cost of work in harvesting of maize.

Body Mass Index
Knowledge of respondents and limitations from physical point of view will help to determine their work–demand fitness compatibility. The height and weight of a person are also indicative of one’s fitness. For calculating the BMI, weight and height of the women farmers were taken. The height of the subjects was measured using an anthropometric rod and weight by bathroom weighing scale. BMI was studied as per the classification given by Garrow (1984). It was measured by Quetelet’s Index. The formula for calculation of BMI is: BMIðkg=sq:mÞ by Quetelet's Index ¼

Blood Pressure
Blood pressure is directly proportional to the amount of work done. The normal range of blood pressure ranges from 80 to 120 mmHg. It tends to increase with the amount of work done, thus increase physiological cost of work. Respondents’ blood pressure was measured by sphygmomanometer.

Physiological Variables
In physiological variables, the energy expenditure and physiological cost of work were calculated and results drawn. The calculation of average heart rate was one to calculate energy expenditure as well as physiological cost of work.

5 Measurement of Heart Rate for Calculation of Physiological Cost of Work Instrument—Heart Rate Monitor Circulatory stress was evaluated from the cardiac cost of work and cardiac cost of recovery. The cardiac cost of recovery is the total number of heart beats above the resting level occurring between the end of the work and return to the resting state (Saha 1999). The following formulae was used to calculate the total cardiac cost of work (TCCW) and physiological cost of work (PCW) (Singh et al. 2007). After preparing the subject for the experiment, the subject was asked to sit in shade in a relaxed position for 10 min. This was followed by taking resting heart rate for 5 min. The women were asked to perform the activity. During performance of activity, working heart rate was taken for 20 min. Immediately after the termination of the activity, the subjects were given rest and recovery heart rate was recorded for 5 min duration. Heart rate (HR) for every minute was recorded.
5.1
Calculation of Physiological Cost of Work
Heart rate data were used to calculate Physiological Cost of Work ¼
Total Cardiac Cost of WorkðTCCWÞ Total time of activities
TCCW = Cardiac Cost of Work (CCW) + Cardiac Cost of Recovery (CCR). CCW = Average Heart Rate (AHR) Duration. AHR = Average Working Heart Rate − Average Resting Heart Rate. CCR = (Average Recovery Heart Rate − Average Resting Heart Rate) Duration.
5.2
Biomechanical Variables
Biomechanical variables were calculated by measuring angle of deviation from natural angle of body and rapid upper limb assessment (RULA), and the results were drawn.

Measuring the Angle of Deviation
It was done in order to know the type of posture used in performing the activities in terms of standing, sitting, squatting, bending, and various combinations of these activities. The angle of body deviation was mainly focused on angle of the backbone. More the angle of deviation from normal, more will be the stress on the backbone, hands, and other body parts; hence, more will be the fatigue. For calculation of angle of deviation, the following steps were taken: • The subjects were asked to keep natural body posture which they adopt while not doing any kind of activity in a particular body posture of either sitting or standing. • The photographs were taken, and with the help of photographs in natural position, the angle of deviation was measured. • For measuring the angle of deviation, the photographs were placed on an empty white wall with the use of projector, and with the help of goniometer, angle of deviation was measured. • Similarly, the photographs were taken of the body parts involved in activity were elicited while performing the activity and the same procedure was followed. • The deviation between natural posture and working posture was illustrated in the results.
5.2.2
Rapid Entire Body Assessment (REBA)
• REBA is a postural targeting method for estimating the risks of work‐related entire body disorders by swift and methodical assessment of the postural risks of workers. REBA was developed by Hignett and Mc Atamney for assessing workers’ postures for determining risk index of work‐related musculoskeletal disorders (WRMSDs). Important tasks for each job are selected first. For each task, postural factors are assessed by assigning a score to each associated body region • The Group A (trunk, neck and legs) postures and the Group B (upper arms, lower arms, and wrists) postures for left and right sides of the body was scored. For each region, there is a posture scoring scale plus adjustment notes for additional considerations. Then, we scored the load/force and coupling factors. Finally, the activity was scored, and the scores from Table A for the Group A posture scores and from Table B for the Group B posture scores were found. Score A is the sum of the Table A score and the load/force score. Score B is the
6
H. Jain et al.
sum of the Table B score and the coupling score for each hand. Score A gives the row, and score B gives the column in Table C. Score C is read from Table C where this row and column coincides. The REBA score is the sum of the Score C and the activity score.
5.2.3
REBA Decision
After the data for each region were collected and scored, tables on the form were then used to compile the risk factor variables, generating a single score that represents the level of MSD risk as outlined below: • • • • •
1 Negligible risk, no action required 2–3 Low risk, change may be needed 4–7 Medium risk, further investigation, change soon 8–10 High risk, investigate and implement change 11+ Very high risk, implement change.
As seen, the score 1 represents the user to be at a negligible risk and does not require any corrective action to be taken. Scores ranging from 2 to 3 and 4 to 7 mean the user is at low and medium risk, respectively, and that further investigation is required to see if any changes are needed to be made. If the score is more than 8, it would mean the user is at high risk and needs to implement necessary changes instantly to correct the incorrect posture.
6 Information Regarding Improved Tools Used for Harvesting of Maize • The harvesting of maize was very tedious activity because of the thickness of the stem. The women farmer used conventional sickle which was non serrated and heavy in weight. This sickle requires high amount of force to cut the stem. • In the present study, two types of improved serrated sickles in which one was replacement of conventional sickle which is used for all crops and the other one named Laxmi sickle was specially designed for harvesting of maize crop by scientist of Dapoli.

The data were collected personally by the investigator by using tools explained above for assessment of drudgery. Pre- and post-intervention data collection for human cost of work were also done and impact of improved technology was also assessed.
7 Results and Discussion Maize harvesting activity was also one of the women-dominated activity and had lot of physiological load and was drudgery prone to women. Traditionally, harvesting is done by conventional sickle which was found very heavy in weight and causes injuries to women’s hand, wrist, etc. It also requires lot of force to perform task as the maize stem is very thick. Due to application of force, women felt pain in wrist.

The two types of improved sickles with different designs and dimensions were introduced, and the data were collected on psycho-physiological cost of work with the use of conventional and improved sickles, and the variation in the results was evaluated. The results are presented below.
7.1
Physical Characteristics of Subjects
For the assessment of psycho-physiological cost of work, the data were collected from 10 purposively selected subjects who were willing to participate in exploratory research. The psycho-physiological cost of work was calculated for both conventional and improved methods, and impact was illustrated in results. Table 1 revealed the physical characteristics of the women subjects selected for experimental work. The mean age of subjects was 33.38 years, mean height 159 cm, and mean weight 56.5 kg.
7.2
Health Status of Subjects
To avoid any experimental error and to minimize the effect of poor health status on women’s working capacity, total 30 subjects who belonged to age group of 25– 35 years having normal height, weight, BMI, blood pressure, heart rate and no history of chronic illness were selected purposively for the experimental purpose (Table 2).
7.3
Physiological Variables
Physiological variable, energy expenditure, and physiological cost of work were measure and the data compared with the use of conventional sickle. In the harvesting operation, conventional sickle was compared with two improved sickles. The summary of the data depicted the energy expenditure was 12 kJ/min which decreases when improved sickle I 10.22 kJ/min and improved sickle II 10.49 kJ/min were used. PCW was also high when conventional sickle

(37.1) was used and decreased when Improved sickle I (33) and conventional sickle II (25.3) were used. Hence, it can be concluded that both the Sickles I and II were found efficient compared to conventional sickle on the basis of physiological variables. The data concluded that while working with improved sickles, the TCCW and PCW reduce. The data of both sickles were also compared, and it was found that sickle Laxmi was more effective in reduction of TCCW and PCW compared to improved Sickle I.
7.4
Output
The data presented in Table 3 depict that with the use of conventional sickle, the output was 150 m2/h which was increased up to 16.66%, i.e., 175 m2/h with the use of improved sickle I, whereas with the use of improved sickle II, output increased up to 26.66%, i.e., 190 m2/h. Thus, the human cost of work pertaining physiological variable was low while using improved technology as compared to conventional one.
8 Biomechanical Variables Biomechanical variable, i.e., angle of deviation of body, was measured, and with the use of REBA worksheet, the body discomfort category was studied.

action category was found in “Medium Risk” side which remained same with the use of improved sickle. It was observed that the REBA scores decreased but the category remained same which indicated that more interventions needed in this field. Hence, the data concluded that with the use of improved sickles the angle of back and wrist was reduced, but the angle of neck remained same but the reduction in the back and wrist angle made the work of the women farmers easier and efficient. Thus, the human cost of work pertaining biomechanical variable was low while using improved technology as compared to conventional.
9 Summary and Conclusion The human cost of work was calculated on physiological variable and biomechanical variable. The results of these variables are summarized below: • In the physiological variable, heart rate, energy expenditure and physiological cost of work were calculated for weeding, harvesting and maize shelling activity. The data concluded that all these parameters were high when women uses the conventional tools compared to improved tools. Hence, improved sickles were found more efficient compared to conventional sickle and manual work. • The data of biomechanical variable were calculated by calculating the angle of deviation of various body parts while performing activity and rapid entire body assessment. The data revealed that in all the operations the use of improved tool

reduces the angle of deviation from natural angle which leads to reduction of MSD and postural discomfort. All the improved tools were designed ergonomically; hence, their use reduced the angle of deviation of body and made women farmers to adopt natural posture while at work. RULA scores also revealed that in conventional tools there was high risk of MSDs which was reduced with the use of improved tools.

Ergonomical Evaluation of Knapsack Sprayer P. U. Shahare, V. V. Aware, N. A. Shirsat, and S. V. Pathak
1 Introduction Insecticides and fungicides are usually applied as foliar sprays. Herbicides are mostly sprayed either onto foliage or the soil. Thus, spraying of liquid and wettable powder formulations is the most common method of application, and thus, wide variety of spray apparatus has been developed. Depending upon the type of agricultural practices and economic development of area, different types of sprayers are used. In most of Asian countries, most chemicals are applied with the help of small hand-operated hydraulic sprayer (Bateman 2006). The main function of a sprayer is to break the liquid into droplets of effective size and distribute them uniformly over the surface or space to be protected. Another function is to regulate the amount of insecticide to avoid excessive application that might prove harmful or wasteful. A sprayer that delivers droplets large enough to wet the surface readily should be used for proper application. Knapsack sprayers are manually operated pest control equipment widely used by Indian farmers. Knapsack sprayers are commonly used to apply pesticides or other agricultural chemicals. Lever-operated knapsack sprayers in terms of material and sophistication, their basic operation is becoming more prevalent on small farms, in nurseries, and in forestry; they are also utilized for agricultural research and extension works. As the knapsack sprayer is a manually operated tool, its performance depends upon equipment design as well as the worker’s ease of operation. If ergonomic aspects are not given due consideration, the worker may have to take long and/or frequent rest pauses during work and the work output will be less (Ghugare et al. 1991). While operating a sprayer, the head and neck of the operator fall forward to counterbalance the weight of the sprayer. The straps of the sprayer cut deep into P. U. Shahare (&) V. V. Aware N. A.

muscles, and severe discomfort is felt in the clavicular region. Due to continuous operation of the lever, discomfort is also felt in the shoulder and arm regions. The ergonomic evaluation of the sprayer may provide preliminary information about physical stress on the operator during operation. Number of knapsack sprayers of different make are available in the market. In order to know its performance of available knapsack sprayer (Make: Surya Agrotech. Indore, Model: Jai Kisan), work of its ergonomical performance was undertaken.
2 Materials and Methods The ergonomic evaluation of the knapsack sprayer was undertaken. The maximum aerobic capacity, energy cost of operation, grading of energy cost, acceptable workload, and assessment of overall discomfort rating (ODR) and body part discomfort score (BPDS) in the operation by different workers were computed. A typical hand-operated knapsack sprayer (Make: Surya Agrotech. Indore, Model: Jai Kisan) consists of a plastic tank of 16 L capacity, a connecting hose with a lance and a nozzle, leaver for producing pressure. Two shoulder straps were attached to the tank for fixing sprayer on to the operators back. Selection of subjects plays a vital role in conducting the ergonomic studies. The subject should be without any major illness and handicaps. Maximal oxygen uptake, heart rate, and muscle strength decrease significantly with old age. The maximum strength or power can be expected from the age group 19–35 years or 25–35 years. However, it was observed that workers from 19 to 45 years of age were engaged in farm operation in Konkan region; hence, the age group of the selected subjects was from 20 to 45 years considering that the subject should be a true representative of the user population. Computerized bicycle ergometer (Monarkergomedic 839E) was used as loading device, and computerized energy measurement system (K4b2) was used for measuring heart rate and oxygen consumption rate of subject. Calibration of subject is shown in Fig. 1. Bicycle ergometer is a test cycle which has an adjustable brake system where the brake force can be read in kg or N. The actual brake power is showed in watt or kcal on the computer. The ergometer is equipped with computer showing pedal revolution per minute, heart rate (bpm), exercise time in minute and second (time), cycle speed in km/h or mile/h, covered distance in kilometer or mile, burned calories (kcal) and the power on the cycle (Watt). For energy measurement, K4b2 of portable unit and receiver unit was used. The portable unit contains the O2 and CO2 analyzers, sampling pump, barometric sensors. It is powered by the rechargeable battery fixed to the back side of the harness. K4b2 is also provided with a small display, the portable unit shows in real time parameters as VT, VE, VO2, VCO2, HR, battery charge level, temperature and

barometric pressure. Besides data processing and presentation, the portable unit has the functions like subject data input, environment data input (humidity), gas and turbine calibration (automatic), memory functions, test data management and data loading to a PC (via RS 232). Calibration of subject was carried to determine the aerobic capacity of subjects. The aerobic capacity was assessed through conducting sub maximal tests on computerized bicycle ergometer (Monark, Ergomedic 839E). The subject was asked to pedal the bicycle at a pedaling rate of 50 rpm. Pedaling speed is maintained by using metronome. The workload was automatically increased by 15 W at an interval of 2 min by bicycle ergometer. The heart rate and VO2 values are directly downloaded to the computer breadth by breadth. A target heart rate was taken as approximately 75% of the age predicted maximum heart rate. The maximum heart rate attainable by the subject was computed by the following relationship. HRðmaxÞ ¼ 220 age in years Every test was continued for 16 min duration or up to the period, subject had fully exhausted, whatever was reached earlier. Correlation between heart rate and oxygen consumption rate at specified sub maximal workloads were developed and the regression line was extrapolated to the age predicted maximum heart rate and VO2 max corresponding to HR max was noted. The maximum aerobic capacity also called as maximum oxygen uptake capacity or VO2 max. The acceptable workload (AWL) for Indian workers was the work consuming 35% of VO2 max (Saha et al. 1979). To ascertain whether the operation of the selected implement is within the
18
P. U. Shahare et al.
acceptable workload (AWL), it is necessary to compute the VO2 max for each subject. The intersection of the computed maximum heart rate of the subjects with the plotted calibration chart line of fit to the oxygen uptakes defines the maximum aerobic capacity (VO2 max) of the individual. The VO2 max for all the subjects was computed and recorded.
3 Results Ergonomical evaluation of hand-operated knapsack sprayer was conducted for assessing its suitability for spraying with the selected subjects. The average heart rate from 6 to 15th min. of operation was used as working heart rate for the further calculation and analysis. The same procedure was adapted to all the selected subjects and heart rate, oxygen consumption, energy cost of operation, acceptable work load, overall discomfort rating, body part discomfort score were determined. The predicted maximum heart rate of the ten men subjects varied from 159 to 189 bpm. The mean value of predicted maximum heart rate of selected subjects was 167.6 bpm. The maximum aerobic capacity of the selected ten men subjects varied from 1.70 l/min to 2.66/min. The average value of VO2 max of all selected subjects was 2.16 l/min. Individual differences in the value of the VO2 max were due to the differences in the ability to supply oxygen to the muscles and also due to genetic factors. The recorded values of max. heart rate and max. aerobic capacity are shown in Table 1.

Ergonomical Evaluation of Hand Operated Knapsack Sprayer
Ergonomical evaluation of hand-operated knapsack sprayer was carried out in terms of following parameters.
3.1.1
Working Heart Rate and Oxygen Consumption
The heart rates of ten male subjects were measured, while operating the hand-operated knapsack sprayer at Department of Farm Machinery and Power, College of Agricultural Engineering and Technology, Dapoli. The heart rate values (HR) recorded in the computerized heart rate monitor during the operation of spraying. The corresponding values of oxygen consumption rate (VO2) of the subjects were predicted from the calibration chart of the corresponding subjects. The oxygen consumption rate as percent of VO2 max is presented in Table 2.
3.1.2
Energy Cost of Operation
The energy expenditure in the operation of spraying for all the subjects was calculated by multiplying 20.88 kJ/l (O2 calorific value) to the oxygen consumption values which was predicted from 6 to 15th minute heart rate of operation. The values are furnished in Table 3.
