Comparison of social skills of students in in-person training and online system

Background and Objectives:The computer is used as a powerful yet cost-effective tool in people's lives for any work or activity. The use of computers in education has increased dramatically in recent years, and computers and related technologies are now used in many schools around the world. Up to recently people should gather to learn in a specific place and time, but nowadays by the advancement of technological infrastructures and the Internet this need has vanished to a great extent. Soon everyone is able to learn anything, anywhere, at any time. This is accomplished under the umbrella of a new educational system, called e-learning. Social skills include components. Tolerance, how to react in the face of conflict, critical thinking, the decision to accept or reject an opinion and success based on logical reasons and evidence, responsibility, taking on a job or task and being accountable for it, activity Group activities, participation in group activities, duty, self-control, empathy, gaining, enriching and developing new relationships with other people in the community, respecting others, paying attention to relationships that preserve the social status of oneself and others, and finally, cooperation and coordination with the actions of others towards a common goal are components of social skills. Of all the organizations that play a key role in the socialization of individuals, educational systems are the first official place to gain social experience and the most basic element of social development of individuals because the education system of any society. It is the foundation of the social, economic, political and cultural development of that society. The purpose of this research was comparing the social skills of students under conventional training and e-learning education system. Methods:  The research method is quasi-experimental with two experimental groups. The first comparison was done using a “Pre-Test” and second comparison was also done using a “Post-Test”. A total of 48 people were randomly selected as a sample group. These two groups were similar and comparing the dependent variable was done at the same time and under the same condition.  The social skills questionnaire By Garsham & Elliot was used. The Analyze of Covariance (ANCOVA) was used for analyzing data. Findings: The results showed that there are significant differences between the two groups and e-learning environment in terms of social skills and social skills components of users of this environment has shown better performance in comparison to Face-To-Face training. Conclusion: The results of the analysis of research data indicate that the e-learning environment has a positive effect on the level of social skills and its components on students. Students in the e-learning environment scored higher than the other group in the traditional learning environment. This indicates the effectiveness of the environment designed for e-learning in the level of social skills

Investigation and identification of helminth parasites in five fish species of Anzali Wetland

This study aimed to identify of helminth parasites in some native and economic fish of Anzali wetland was performed. 314 fish specimens, including: Alburnus hohenackeri (60 Specimen), Blicca bjoerkna (75 Specimen), Hemiculter leucisculus (75 Specimen), Pseudorasbora parva (52 pcs) Rhodeus amarus (52 Specimen), from Cyprinidae (Cyprinidae), during 1 year (2012-2013) and seasonally, from three different stations (Shijan, Pirbazar and Pasikhan) via gill net (50-70 mm) and fyke net were sampled. Samples were transported to the Inlandwater Aquaculture Institute in Bandar Anzali. In the laboratory, After biometry and determine the age and sex of fish, different body parts for searching of parasites were checked and parasites by using identification keys were identified. As a result of this study, 9 species of helminth parasites of fishes were identified include: Gyrodactylus sp., Dactylogyrus sphyrna , Dactylogyrus sp., Ligula intestinalis, Diplostomum paraspathaceum, Diplostomum spathaceum, Diplostomum sp., Posthodiplostomum cuticola and Rhabdochona denudate. The highest frequency of parasites in trematodes (in 5 fish species studied) and the minimum frequency in cestodes (each at 1 fish species studied) were seen. According to statistical analysis using Chi-Square test and KruskalWallis, the pollution of the sex, weight, length and sampling stations, there is no statistically significant difference (P> 0.05)

Short communication. Dietary supplementation effects of zinc acetate and magnesium sulfate on performance and antioxidant status of broilers under continuous heat stress

The aim of this study was to investigate the effects of different dietary levels of zinc acetate (Zn; 0, 30 and 60 mg kg-1) and of magnesium sulphate (Mg; 0, 300 and 600 mg kg-1) on performance and blood antioxidant status of broilers under continuous heat stress. For this purpose, four hundred and fifty one-day-old male chicks were used in a 3 × 3 factorial experiment from day 1 to day 42 of age. The inclusion of 30 mg Zn kg-1 increased the body weight gain and the average feed intake and declined the feed conversion ratio (FCR). Although there were no differences between the treatments for FCR, the supplementation with 30 and 60 mg Zn kg-1 decreased the FCR regardless the Mg level. The dietary supplementation with 30 mg Zn kg-1 decreased both blood glutathione peroxidase and superoxide dismutase activities regardless the Mg level. In addition, neither Zn nor Mg influenced the blood total antioxidant capacity content at the end of the experiment. Blood malondialdehyde (MDA) decreased as dietary Zn supplementation increased. The MDA reduction when diet was supplemented with Zn was not obvious at higher Mg level (interaction Zn × Mg, p<0.05). In conclusion, dietary addition of Mg does not significantly influence either the performance or the antioxidant status of broiler at 42 d of age under heat stress but supplementation of 30 mg Zn kg-1 decrease the blood MDA concentration and improves the performance

Servey Impact of Activated Alumina in Fluoride Concentration Peresent in Water and Appointment Adsorption Isotherm and Kinetics

Backgrounds and Objectives: Determination of Fluoride in drinking water has received increasing interest, duo to its beneifical and detrimental effects on health. The aim of this research is investigation of Effect of  activated alumina in fluoride concentration reduction in drinking water."nMaterials and Methods: Expriment in batch system and with change effective parameters such as pH(5, 7,9), equilibration time (30, 60, 90, 120 minute), initial fluoride concentration(1.4, 2, 2.4 mg/l) and activated Alumina dosage (0.1, 0.2, 0.3 gr/l) was investigated. Also found data of this research were fited with Langmuir and Freundlich models, kinetic data with pseudo- first order, pseudo- second order and modifited pseudo- first order  models."nResults: The results showed that with increasing of pH of solution, removal efficiency was decreased and optimum pH was found to be in the range of 5 to 7. Also removal efficiency of fluoride was increased with increasing of adsorbent dosage and decreasing of initial concentration of fluoride. Adsorption isotherm data show that the fluoride sorption followed the Langmuir model (r2=0.98). Kinetics of sorption of fluoride onto Activated alumina was well described by pseudo- second order model."nConclusion: The concentration of Activated Alumina had significant effect on the reduction of fluoride ions concentration in water.The higher fluoride removals were observed for batch experiments at pH=5 because no free fluoride ion is present in the solutions, and it could be casued by electrostatic interactions between the surface of alumina and the dominant fluoride species in solution The kinetic model can adequately describe the removal behaviors of fluoride ion by alumina adsorption in the batch system

Establishing global school feeding program targets: how many poor children globally should be prioritized, and what would be the cost of implementation?

The creation of Human Capital is dependent upon good health and education throughout the first 8,000 days of life, but there is currently under-investment in health and nutrition after the first 1,000 days. Working with governments and partners, the UN World Food Program is leading a global scale up of investment in school health, and has undertaken a strategic analysis to explore the scale and cost of meeting the needs of the most disadvantaged school age children and adolescents in low and middle-income countries globally. Of the 663 million school children enrolled in school, 328 million live where the current coverage of school meals is inadequate (20% anemia and stunting), and of these an estimated 73 million children in 60 countries are also living in extreme poverty (<USD 1.97 per day). 62.7 million of these children are in Africa, and more than 66% live in low income countries, with a substantial minority in pockets of poverty in middle-income countries. The estimated overall financial requirement for school feeding is USD 4.7 billion, increasing to USD 5.8 billion annually if other essential school health interventions are included in the package. The DCP3 (Vol 8) school feeding edition and the global coverage numbers were launched in Tunis, 2018 by the WFP Executive Director, David Beasley. These estimates continue to inform the development of WFP's global strategy for school feeding
