Small-sized sugarcane harvesters (SSHs) were field-tested to evaluate their performance and adaptability with the aim of improving their operation under wet conditions caused by frequent rain during the harvesting season. SSHs performed better than larger machines in wet fields, harvesting 120 t/ha of yield and lodged sugarcane. Harvesting losses with SSHs were almost the same as those with middle-sized harvesters (MSHs) in small fields with narrow headlands. Stool damage, stools pulled out and extraneous matter in wet fields where SSHs were used were lower than those where MSHs were used. In addition, SSHs can work in the narrow row spacing, resulting in increased productivity. Overall, it was shown that SSHs were highly adaptability in the wet sugarcane fields of Okinawa. © 2015 Asian Agricultural and Biological Engineering Association.

This study was conducted to clarify nutritional status and associated factors in 5-24 month old children in the district of Batouri, Republic of Cameroon. Mothers were interviewed using a semistructured questionnaire, and the child's weight, length, head circumference, and mid-upper arm circumference was collected. The data were compared with child growth standards proposed by the World Health Organization using Z-scores; χ2-test, Fisher's exact test, and Wilcoxon rank sum test were used to determine variables associated with malnutrition. A total of 100 mother-child pairs participated in this study; valid data from 100 pairs were subjected to analysis. The percentages of children with malnutrition indicators were wasting (6%), stunting (31%), underweight (14%), and low mid-upper arm circumference (16%). Five factors were found to be statistically significant in their association with the children's malnutrition: mother's age, child's age, mother's educational level, mothers who had family planning information, and the source of tap water. A high percentage of stunting was positively associated with a high percentage of chronic malnutrition. We speculate that insufficient nutrition was more likely to begin after weaning. © 2015 Wiley Publishing Asia Pty Ltd.

Background.Oxidative stress is an important factor in the pathology of age-related hearing loss. Recent animal studies have reported that ultraviolet radiation in sunlight is related to systemic induction of oxidative stress. Chronic sun exposure leads to photodamaged skin, which is manifested as facial skin wrinkling and hyperpigmentation. We hypothesized that sunlight exposure, as assessed by the severity of facial skin photodamage, might be associated with hearing impairment through an oxidative stress mechanism. To examine this, we performed a cross-sectional analysis by using the baseline data from a community-based cohort study of older Japanese.Methods.A total of 805 residents (342 men and 463 women) aged 65 years or older living in Kurabuchi Town, Gunma prefecture, Japan, were examined between 2005 and 2006. Facial skin condition was quantified by image analysis of standardized facial images. Hearing impairment was defined as a failure to hear a 30-dB signal at 1 kHz and a 40-dB signal at 4 kHz in the better ear in pure-tone audiometric tests.Results.In men, facial wrinkle was positively associated with hearing impairment (for highest vs lowest: multivariate-adjusted odds ratio, 2.16; 95% confidence interval, 1.00-4.66; p for trend =. 01). Stratified analysis by age, educational level, smoking status, sunscreen or foundation use, and diabetes showed results similar to those for men as a whole. This association was particularly pronounced in men with the low levels of antioxidants and without occupational noise exposure. We observed no apparent association in women.Conclusions.The results support the hypothesis that chronic sun exposure is a risk factor of hearing impairment. © 2012 The Author.
