Conventional and improved methods of aonla pricking were evaluated ergonomically on an experiment conducted for 20 minute with women workers. The working heart rate, energy expenditure rate, total cardiac cost of work and physiological cost of work with conventional tools varied from 93-102 beats.min -1, 6-7.5 kJ.min -1, 285-470 beats, 14 -23 beats.min -1 while with machine varied from 96-105 beats.min -1, 6.5-8 kJ.min -1 , 336-540 beats, 16-27 beats.min -1 respectively. OWAS score for conventional method was 2 indicating corrective measures in near future while with machine was 1 indicating no corrective measures. Result of Nordic Musculoskeletal Questionnaire revealed that subjects complaint of pain in back, neck, right shoulder and right hand due to unnatural body posture and repetitive movement with hand tool. Moreover pricking was carried out in improper lighting conditions (200-300 lux) resulting into finger injuries from sharp edges of hand tool, whereas with machine no such problems were observed. Output with machine increased thrice than hand pricking in a given time. Machine was found useful in terms of saving time, increased productivity, enhanced safety and comfort as involved improved posture, was easy to handle and operate, thus increasing efficiency of the worker leading to better quality of life. © 2012 - IOS Press and the authors.

Aonla is an important Indian fruit crop with great potential for processing into various quality products. Aonla preserve making is an important economic activity in our country. The pricking methods are age old, hence a hand operated aonla pricking machine was introduced in preserve making industries to speed up the pricking task. OWAS and RULA two of the most commonly used ergonomic assessment tools were evaluated for their efficacy in the assessment pricking along with Rating of perceived exertion scale. Analysis of working posture using RULA revealed that the pricking task with existing methods i.e. fork and hand tool requires immediate investigation and changes in working posture while with machine pricking investigations and changes are required soon. The results of OWAS indicated that the posture maintained while pricking with existing methods need to be changed in future planning while with machine was acceptable. The subjective assessment revealed that machine pricking was less exerting activity as compared to the existing methods. The preserve prepared from machine pricked fruit was most acceptable among consumers. Hence, in the form of machine ergonomic intervention was brought about in preservation industries which have proved beneficial for workers in terms of their safety and productivity. © 2012 - IOS Press and the authors.

The study was conducted on 20 farm workers to identify the occupational health hazards in threshing operation. Four different protective masks were given and tested on various parameters. Respondents reported respiratory health problems which were mainly due to heat and organic dust in the surroundings. All respondents reported irritation in eyes and throat followed by nose (85.0%) and ears (75.0%). Musculo-skeletal problems were reported showing severe to very severe discomfort in lower arms (m.s. = 3.8), upper back (3.6) and upper arms (3.4). Overall discomfort score (ODS) was 7.6 depicting high level of discomfort. Peak expiratory flow rate was reduced by 6.6 % depicting reduced capacity of lungs after day long work in polluted environment. Hood mask was highly acceptable as it showed lowest breathing resistance. Leakage of dust from sides and rate of sweating was medium. Hence, use of hood mask would be helpful to achieve the ergonomics objective of reducing health problems and improving performance. © 2012 - IOS Press and the authors. All rights reserved.


Objectives To assess the family history of stones and association of mineral intake with gender, age and income of kidney stone patients. Methods A total of 130 kidney stone patients were selected randomly from Kangra district of Himachal Pradesh and family history of stones and mineral intake was assessed. Results Out of selected patients, majority (80.77%) were first time stone sufferers. There was significant (at 1 % level) association between family history of kidney stone patients with respect to gender of patients. Further study revealed that the intake of sodium, calcium, magnesium and phosphorous was higher than recommended dietary allowances (RDA). Among male patients, the intake of sodium, calcium and magnesium was higher for age group III (above 45 y) and intake of potassium and phosphorous was higher for age group I. In female kidney stone patients, intake of sodium, calcium and phosphorous was high for age group II, intake of potassium was high in case of age group I and intake of magnesium was high for age group III. Regression studies revealed that there was significantly higher intake of calcium and phosphorous by male kidney stone patients than female kidney stone patients. With the increase in age, the intake of calcium and phosphorous decreased. Conclusions Assessment of mineral intake is necessary to enable the health care providers, to give advice and suggestions to the patients to carry out preventive measures in reducing the risk of prevalence of kidney stones in this area and further advice to the suffering patients to prevent the recurrence of stone formation. © Dr. K C Chaudhuri Foundation 2013.
