The concept of percepted organizational innovation refers to perception of employees about organization’s support from innovation leading to increase of satisfaction and commitment of employees. Researchers have examined the effect of organizational factors on percepted organizational innovation in their studies. The aim of this paper is to study the relationship between organizational climate and perception of organizational innovation in regards to the role of gender as a moderating variable. The results are drawn from emprical research among 150 headquarter experts of Khorasan Regional Electricity company. Questionnaires were used to collect the data and relevance thereof regarding the content and factorial analysis was confirmed using statistical software such as SPSS and AMOS. The outcomes resulting from the model test showed that only 3 aspects of organizational climate including autonomy, cohesion and trust, favors perception of oganizational innovation; and there is a strong bond between organizational climate and percepted innovation. Moreover, the hypothesis concerning the moderating role of employees’ gender in the relationship between organizational climate and organizational percepted innovation was not affirmed.

The use of herbal plants to cure the large number of diseases is very common among people. Naturally in every menstrual period the blood loss is about 30 to 60 ml. In case, the amounts get to 80 ml or more, the side effect like anemia will be outbreak. The purpose of this study was to determine the efficiency of herbal plants (Anthemis, Salvia, and Zataria) on the intensity of menstrual period bleeding. Thus, 125 female mature students were observed for three consequential periods. They divided to three groups randomly; herbal drug, placebo, and without any manipulation. The two first groups were drinking mixture decoction of the 15 mg herbs in 3 doses, three first days of periods, then, they filled up the questionnaire after each period. The data were analyzed by descriptive tests, ANOVA, and non parametric tests (Kendal & Friedman). The results showed that decoction of this herbal plants could decrease the intensity of menstrual bleeding significantly (P = 0.000, P = 0.02, α = 0.05).

This study was conducted to examine the effect of different amounts application of urban compost on the growth and yield characteristics of vetch plants and rate of nitrogen, potassium, phosphorous and also organic matter in soil. In this experiment, five treatment of various amounts of compost (0, 15, 30, 45, 60 ton/ha) in the base of complete randomized blocks design with 3 replication in the research field of Abureyhan campus, University of Tehran. Results showed that the compost amount had a meaningful effect on the shoots dry weight, plant height, 1000-grain weight, the number of seeds in pod, protein and seed yields of Mungbean plant and rate of soil nitrogen, potassium and phosphorous. Based on the results between treatments, application of 60 tones of dry compost, which is the highest applied rate, resulted in the highest dry-weight in the shoots, plant height, 1000-grain weight, the number of seed in pod. The highest rate of protein yields was obtained in two 45 tons/ha and 60 tons/ha treatments respectively. Considering the fact that the increase in the amount of compost affects the rate of nitrogen, potassium and phosphorous in soil positively, one of the reasons for increase of yields and yield components in mungbean can be attributed to the improvement of nutritional conditions and increase in the soil physicochemical properties.

This experiment was conducted in research field of abureyhan campus, university of Tehran, to study the effect of different amounts of municipal solid waste compost on soil nutrients and growth and yield of forage corn. Five treatments (include of 0, 15, 30, 45 and 60 ton compost per ha) were used in a complete block design with three replications. According to the result, height and dry and fresh yield increased by increase in amount of compost used in soil. The highest corn forage yield was obtained from 60 and 45 ton.ha-1 compost treatments. Soil Ca, K, Mg, P and organic matter had positive correlation with compost application amount. During time in growth season, soil nutrient concentration and organic matter were decrease and differences between treatments were decreased at the end of the season. Also, soil EC and pH were increased by compost application, but decreased at the end of season due to leaching and plants uptake and due to soil buffering property, respectively. Finally, soil characteristics and corn growth and yield were improved by increase in the compost amount.

Neonatal hypothermia is a frequent medical problem in low socioeconomic Countries. It is a significant perinatal problem contributes to increase morbidity and mortality. The goal of this study was to determine the frequency of neonatal hypothermia and associated risk factors. A cross-sectional and randomized study of neonatal hypothermia was performed on 1871 newborns delivered during 12 months period, form October 2002 to September 2003, at Imam Khomeini hospital of Ahvaz. Auxiliary temperature measurement was made during the first 24 hours period after birth randomly.The study showed that 7.48 % of the newborns were hypothermic. Cold stress and moderate hypothermia occurred in 72.8 and 27.2 % of newborns respectively. Severe hypothermia was not detected in any of them. The most frequency of hypothermia occurred during 15-20 hours after birth. The frequency of hypothermia in low birth weight infants was 25.7 % (P<0.05). Breast feeding was performed in 65.7 % of infants in first hour of life and 37.9 % of hypothermic infants belong to this group (P<0.05). Route of delivery, seasons, gender and bathing did not affect the frequency of hypothermia. No significant differences in the frequency of hypothermia between Winter and Summer seasons were recorded. the finding of this study demonstrated that low-birth weight and feeding after first hour of life was significantly associated with neonatal hypothermia. It is essential that adequate training of care taking staff on these findings will be useful in prevention of this phenomenon
