The impact of social network-based nursing care training on oncology nurses� occupational stress and self-efficacy: Non-randomized clinical trial

Background & Aim: Inadequate clinical knowledge is one of the leading causes of stress and low occupational self-efficacy among nurses. Nursing training can enhance self-efficacy and reduce stress. Therefore, this study aimed to determine the effect of social network-based nursing care training, using mobile phones, occupational stress, and self-efficacy among oncology nurses. Methods & Materials: This non-randomized clinical trial study was conducted on 78 nurses working in oncology wards of two selected educational hospitals in Tehran in 2018. The nurses entered the study through available sampling. They were randomly assigned to two groups of control and intervention. Nursing care training in chemotherapy was provided to the nurses in the intervention group through a mobile phone social network for four weeks. On the other hand, the nurses in the control group were provided with the routine training pamphlets and brochures in the oncology ward. The nurses� stress level was examined using an expanded nursing stress scale and their occupational stress was measured using a job self-efficacy questionnaire once before the intervention and then one month after the intervention. The data analysis was then performed according to independent t-test, paired t-test, and chi-square using SPSS software version 16. Results: The two groups were homogeneous in terms of age, gender, work experience, and education. There was no significant difference in terms of occupational stress and self-efficacy between the two groups before the intervention (P<0.05). The changes in the occupational stress score were statistically significant (P<0.05) among the nurses in the intervention group. Moreover, the changes in the occupational self-efficacy score were statistically significant among nurses in the intervention group compared to the control group (P<0.05). Conclusion: Educational intervention through social networking can lead to a reduction of occupational stress and an increase in self-efficacy among oncology nurses. Reducing stress and increasing nurses� occupational self-efficacy will improve their performance at the bedside. This is an easy, inexpensive, and effective training method that can be used by health managers and educators to enhance employee�s performance. © 2021, Tehran University of Medical Sciences.

As investigation of quantity and quality factors and healty condition situation for sturgeon fry in Shahid Marjany and Sade Voshmgir Hatcheries

Survy on some quality and quantity factors on Strugeon fry has been conducted at two ratcheries in cluding Shaiid Marjany and Voshmgear Sad from may to late July for the years 2000 to 2001. Of 64 , 15 and 2 ponds have been randomly collected in 2000 for Voshmgear sad and Shaiid Marjany respectively.In 2001, 17 and 5 out of 65 ponds were collected for the former and latter ones respectively. The items for the quality investigation included : 1- inspection of fry disease 2- inspection of physical and chemical factors for ponds 3- inspection of phytoplankton. Quality investigation was related to count the fry during releasing, growth coefficient and condition factor. No disease was observed for fry in Shaiid Marjany hatcheries Based on 210 and 372 fish examined in 2000 and 2001respectively. In 2000, of 953 fry specimen examined in Voshmgear Sad ,36.1% was infected to Tricodina parasite and 16.4% out of the total 1196 specimen examined in 2001, followed by Jearodactylous parasite.In relation to physical and chemical factors, the average temperature of water was higher than the opitimal one for both hatcheries. Transparency was low wherease NO_3 , NO_2 and aurtophofat was in optimum condition..It was indicated that phytoplanktons belonging to Clorophyta phylum constituted the highest value in terms of biomass , followed by Clorophyta and cyanophyta Ones. The highest abundance was related to pediastrum , cholorella and scenedesmus genouses. It was the same for Shaiid Margany hatchenes. Quality investigations showed that Voshmgear and Shaiid Marjany hatcheries accounted for 836% and 16.4% of the total provience production in 2000. It indicated 59% and 40.36% for the hatcheries respectively in 2001. In 2000, high and low proudction of voshmgear Sad was as 84.4% and 3.8 which was related to Acipenser persicvs borodine , Acipenser guldenstadti brondt respecively. In 2001 , These amounts were as 98% and 0.5% for these species respectively.The highest value of releasing for fish below 3g belonged to to Acipenser persicvs borodine species which was as 76% and 63% in 2000 and 2001 respectively. In 2000 , the hishest and lowest level of proudction at Sahiid Marjany hatcheries was related to Acipenser guldenstadti brondt and Acipenser persicvs borodine species with values of 35.6% and 29.28% respectively. Acipenser persicvs borodine species accounted for 83.5% of the toal fish below 3g, indicating the lowest value in 380 and Acipenser persicus borodine , Huso huso constituted the highest (71%) and lowest (8%) production .The highest level of releasing for fiy (below 39 g) was related to Acipenser persicus borodine species (23.8%)

Study of penculture of the common carp (Cyprinus carpio L.) fingerlings at the Gorgan Bay to the maturity stage (broodstock management)

The aim of present project is study on the possibilities of brood stock production from fingerlings in the penculture condition and the effect of density on it .this project was done during three years with two different treatment and three repetitions in the Gorgan Bay. First treatment with two fingerlings per square meter and the 2nd with four fingerlings per square meter in each pen.To carry out the project at first fingerlings were brought from breeding and recruitment centre –Sijeval (Kolmeh) and the stocked at the earthen pound with concentrated food .After that they were adaptated with brakish water between 7-10 days and transferred to Gorgan Bay for cultivation with average weight of 93.78±32.66 grams and 20.53±2.37 cm in length. It should be noted that 6 pens (which surrounded by nets in the water) were fixed using mast with 15-20 cm in diameter and 5.5 meter in length , Net mesh size was 16 mm with string number 33 of kapron.Feeding was done according to the program two times by giving concentrated food at the period of cultivation Physic -o -chemical factors were measured. biometery was done monthly at each pen and other fishes (unwanted) were observed at the same time. results indicate that in the 1st and 2nd treatments average survival rate was 52.3 and 41 percent respectively with average weight of 410±64.98 grams and 390±52.8 and 28.3±1.79 cm and 27.66±1.57in length. SPSS used to analysethe data such as average length and weight of fish in the treatments and in different months with ANOVA method (p≤ 0.05) . results show that there is no significant difference between treatments. Autopsy observation also showed that fishes (female and male) are mature and histological studies showed that most of observed eggs are entirely mature with 800-1200 micron diameter gonad ( male) were mature at the pen in the Gorgan Bay condition .The male and female hormones were evaluated. 17-B- Estradiol and 11-keto testosterone hormones for adult fish (female and male) parents respectively are similar in dense with those adult fish before injection to use at the artificial breeding. Maturation were verified by autopsy, histology and hormone studies
