Abstract: The article analyzes personal orientation of future specialists’ training under the conditions of educational process profilisation. The concept of educational environment profilisation including methodological, theoretical, practical and subject aspects is developed and submitted. Specific characteristics of the term «profilisation» in the context of educational environment functioning are formulated. The experiment program for studying of personal orientation of future specialists’ training under the conditions of educational process profilisation including stating, forming and resulting stages is developed. Social, didactic, cognitive, professional directed activities of profiled educational process participants are determined as indicators of formation efficiency of future specialists’ personal orientation. Formation of personal orientation of future specialist training under the conditions of educational process profilisation is carried out in the course of forming experiment stage on the basis of social and pedagogical projection within the educational environment profilisation concept. Results of the research at the stages of stating and resulting experiments in control and experimental groups are compared and analyzed.

Abstract: The Mediterranean area is an environment with constraints drastic climate (summer drought, additional stress in littoral zone, poverty of the soils...) controlling the soil and vegetation.The objective of this study is attached to check the effect of the environmental pressures on the Pistacia lentiscus, which is a plant of the sclerophyllous Mediterranean found both in coastal and continental area in the West Algerian. This has allowed us to understand the behavior of some of the morphological and chemical characteristics of leaf material to structuring factors typical of the Mediterranean context at the local and regional levels. To study the morphological characteristics of the leaves (the number of leaves, the leaflets, the thickness of the sheets and material dry...) and the chemical properties (carbon, nitrogen) we analyzed two rank of age of 24 sheets, and each extracted row of 180 branches randomly chosen from 15 trees in a coastal forest in the West of Algeria (Yourjust) Ghazaout wilaya of Tlemcen.Through statistical analysis (ANOVA, text-independent) were compared with leavestaken from a continental forest West of Algerian (Chaabat darou) Beni Ouarsousse wilaya of Tlemcen. The results showed us that at the regional level, where the littoral footprint is important proportions of nitrogen, carbon, SLA, and the number of sheets have been significantly reduced however have noticed an increase in the number of leaflets and LT, and at the level of the age of the leaves we notice that the young leaves are characterized by a larger number with more thickness and a low number of leaflets. This study show how Pistacia lentiscus can adapt with different environments.

Abstract: Cooperative learning is one of popular teaching strategies used in school as an alternative teaching strategy to teacher centred approach. It is believed that through cooperative learning learners become active constructors of the knowledge instead of receivers of knowledge. This case study explores the impact of cooperative learning as used in APOS study, to improve knowledge construction in mathematics from the learners perspectives. Three students were recruited through purposive sampling to share their perspectives on their experiences of working in traditional formation of groups, where students are just given a task to work in groups and submit the work as compared to structured groups following the ACE (Activities-Class Discussion Exercise) teaching style, as proposed in APOS theory. The analysis reveals that learners do not necessary find the traditional form of group work helpful in maximising their learning. They felt that it encourages high achievers to be dominant and the rest uncooperative. Instead, they prefer to first work individually, solving the problem and then have a group discussion to share their thought processes. Based on the participants views, working individually allows for cognitive thinking to take place and group discussion enhances thinking through sharing of thoughts and thus allows for knowledge construction.

Abstract: An efficient control system involves identifying the "unreliable" indicators of product quality and determination their relationship with other indicators of products quality. The main steps of the offered method are: the definition of unbiased estimators of parameters of quality that allows you to define confidence intervals for the mean value; comparison with normative values of indicators obtained the confidence limits and identification of "unreliable" quality indicators. In this example, an "unreliable" indicator of quality products has been identified - indicator of strength of corner joints, and found a linear relationship between the indicator and the indicator of resistance to heat transfer. It was found that in terms of the strength of the corner joints and resistance to heat transfer is necessary to conduct a more thorough monitoring in order to identify and eliminate possible scrap.

Abstract: Localization plays a very prominent role in WSNs. It is essential because if one node contains information placid from physical entity to transfer and the location of other node which is meant to receive is not known then the information gathered becomes feckless. The basic idea in localization involves placing GPS in each and every node in the network to know its location. It results in increase of cost which is not a desirable feature. Moreover the efficiency of GPS is not Satisfactory in monitoring indoor applications. In localization, the distance between nodes is essential which will be further calculated by using RSSI method. RSSI is adopted in many of the localization algorithms because of its low cost and simplicity. In ranging mechanism, Classical Trilateral algorithm is considered but it results distance errors due to instability in equations.The proposed mobile aided Trilateral method results in increasing the network lifetime, reducing the time of estimation, improving the signal strength besides minimizing the energy consumption of nodes. In this method the mobile node moving in random manner gathers the information of neighbouring nodes which will be further useful in Trilateral minimum condition method to localize the unknown nodes position.In this method the distance calculations are performed by mobile node resulting in the minimization of energy usage and distance error associated with neighbouring nodes. As a result the proposed mobile aided method produces the best results in case of signal strength and life time of network when compared to previous Classical Trilateral methods.

Abstract: Education is adversely affected by the loss of learning and teaching time due to safety related problems in schools. School management teams (SMTs) thus need to create proper plans to achieve the desired outcomes or set objectives for a safe learning environment. The Department of Education needs to acknowledge the urgency of providing practical training for all SMTs and educators upgrading their knowledge and skills in safety. An interpretative research paradigm was used to unravel how the participants (n=9) have created their reality regarding school safety challenges in rural environments. The Domino Theory is the theoretical lens that was used in this study. The improper attitude from the DoE regarding safety implementation and monitoring and support tools; improper attitude of the SMTs and educators regarding their role in safety issues and the physical unsuitability of the infrastructure of some schools creates confusion in safety management. In order to improve safety issues in South African schools, urgent training on safety management, implementation and control is required by safety experts hired by the DoE, thereafter ongoing on-line platforms for dealing with relevant unsafe situations at school should be easily accessible to all educators and interested parents, councilors, psychologists and safety officials. Communities of Practice with a focus on school safety should be held quarterly and attended by SMTs and school governing body officials.
