Abstract
The article defines the priorities, principles and main provisions of national forest policy of Ukraine towards European integration. The main objectives and structure of the mechanism of transformation of ecological and economic relations in the forest sector of Ukraine is grounded. The main tasks of transformation of ecological and economic relations in the forest sector should be decentralization of the management system, budget savings and sustainability, sustainable development and ecological security, development of public and private partnership, and welfare of local communities. It justifies priority directions of transformation, which include the system of distribution of powers between central, regional and local levels, the financing system and fiscal regulation in the forest sector, powers and subordination of the organs of ecological control, the organizational forms of companies and associations, the institutionalization of communal and private ownership of forests. Necessary organizational and economic framework for their implementation should ensure the economic mechanisms of transformation of the system of state management of economic processes, financial-credit and fiscal regulation, economic incentives of the deep environmentally friendly forest products, integration of businesses and innovative and investment development of the forest sector, the Institute of ownership of forest land, the property rights of forest users and local communities.
The structure of transformation mechanism of ecological and economic relations in the forest sector is developed. It will allow the use of modern economic methods (de-monopolization and transparent competition on the timber market; economic incentives for deep wood processing; the transition to the new organizational forms of integration of economic entities; the empowerment of local communities and their executive bodies) and the instruments (preferential loans; target financing of large-scale projects at the national level; environmental insurance; transfer pricing; export and import duties; the state order; the state guarantees and subsidies), and to form an effective organizational forms of business entities in the forest sector.
It is concluded that transformation processes should apply to all spheres of economic activities in the forest sector, especially in the following areas: increased powers of the management bodies of the forest sector at the regional and local levels; simplification of procedures for land allocation by local governments to provide additional reforestation; coordination between the organs of ecological control and forest management to strengthen the relationship between the real state of forestry and the system of rational use of forest resources; the introduction of modern forms of enterprise and associations of enterprises at different stages of the reproductive process.
Wood structure of Scots pine (Pinus sylvestris L.) growing on flotation tailings
Authors: Górska Marta , Roszyk Edward 
Published: July 2019

Abstract
The aim of this study was to examine Scots pine (Pinus sylvestris L.) xylem changes caused by heavy metal pollution. Annual rings width, number of tracheids in radial rows and the length of tracheids in the wood from trees growing on post-flotation tailings have been measured. Dimensions of tracheids have been examined separately for early- and latewood of each radial increment. The most demonstrable changes are observed in the tracheids length, which appears to be shorter in the xylem from the industrial area than in the control samples. In the wood from the polluted site, the variability of length of tracheids is increased. Microscopic observations revealed numerous deformations in the xylem tissue and deviations from the standard cell arrangement. Circumferential deformations occurring in the wood structure may indicate the increasing spring frost vulnerability of these trees.
Appraisal of Real Estate with Various Functions in the Context of Sustainable Development
Authors: Adamczyk Tomasz , Bieda Agnieszka , Parzych Piotr 
Published: July 2019

Abstract
The value of a piece of real estate depends on the purpose it is used for and on its function in planning documents. Unfortunately, current land development trends and the provisions of the law that are applicable in these documents often lead to real estate with heterogeneous functions. The valuation of such properties requires a special approach. One method is to divide the prices of real estate similar to the appraised real estate into components that correspond to areas with certain functions. The aim of this paper is to present statistical methods that can facilitate such a solution. The valuation models (parametric and conditional) presented in this article come from geodetic methods for the reconciliation of results. The presented calculations suggest that it is necessary to verify whether the heterogeneous functions of real estate should be considered in its appraisal.

Abstract
Today, research and development (R&D) indices are significant criteria for the development of countries. Therefore, the objective of the present study was to investigate the role and position of research and development units in construction industry from the perspective of construction management. The study is a descriptive survey research. The statistical population comprised the elite members and experts of research and development working in this field who were 81 individuals in total. The study employed Cronbach’s alpha to determine the reliability of the questionnaire. The study also exploited expert judgments of the elite members and experts of research and development in the construction industry to determine the validity of the questionnaire. For data analysis, the study deployed SPSS program. The findings reveal that the challenges existing in research and development centers are divided into the two groups of internal organizational problems and external organizational problems, and it is economically feasible to establish research and development units in the construction industry. In this regard, with a systematic view, the issue of research culture is proposed as the central point of the model.
Effect of Micro Polypropylene Fibre on the Performance of Fly Ash-Based Geopolymer Concrete
Authors: Rajak Manoj , Rai Baboo 
Published: July 2019

Abstract
Geopolymer offers significant promise to the construction world as a possible alternative to ordinary Portland cement (OPC). Like conventional Portland cement concrete, the matrix brittleness in geopolymer composites can be reduced by introducing suitable fibre reinforcement. A few investigations on fibre reinforced geopolymer composites are available. However there is still a gap to comprehend and enhance their performance. This paper describes the effect of incorporating micro polypropylene fibres on the strength and durability characteristics of geopolymer concrete. The engineering and durability properties like workability, compressive strength, split tensile strength, flexural strength, modulus of elasticity, and sorptivity of geopolymer concrete reinforced with micro polypropylene fibres is presented. The effect of the sulfuric acid attack on Geopolymer Concrete reinforced with micro polypropylene fibres is also discussed. The results show that hydrophobic characteristics of the micro polypropylene fibre led to weak contact with the geopolymer binder and hence weakened the mechanical performance of the fly ash based geopolymer matrix. However significant improvements in durability properties were noted.

Authors: Fox Anne E. M. , Iriste Sandra , Bezeljak Petra 
Published: July 2019

Abstract
Having developed and piloted a professional development blended learning course for teachers of home economics with the purpose of promoting a sustainable mindset in their students, we used the written learning journals by the teachers during the 15-week course to detect various aspects of a sustainable mindset, which could be attributed to the course. We assumed that the learning journals of 19 participants might reveal reflections on sustainability, the pedagogy of sustainability, a positive association between sustainability and the pedagogy of sustainability, and the development of a sustainable mindset over the period of the course. The analysis confirmed that the participants reflected a great deal on learning and sustainability as the course progressed; revealing that a positive link between teaching practice and sustainability can be observed. However, the analysis also indicated some important concepts that might have been under-emphasised in the course.

Published: July 2019

Abstract
Teacher empowerment is a central issue in relation to the efforts to improve the quality of education. However, teacher empowerment will remain an abstract idea if its implementation is not supported by an appropriate strategy. The demands for a quality education will be unreciprocated if teachers do not have the opportunity to empower themselves. This research aims to investigate the teacher empowerment strategy in Indonesia, which has been conducted by employing a community-based teacher training program. This study has highlighted several research questions: What is meant by community-based training program? Why is the training program needed? Who is the target of the training program? What model has been used to implement the training? What are the results of the training that has been executed? This research was conducted from November 2018 to January 2019. The research data were collected by means of documentation studies and interviews. The data analysis was carried out quantitatively and qualitatively, where the quantitative analysis was processed based on the document study data, meanwhile the qualitative analysis was performed based on the interview data. The research results showed that community-based teacher training was transformation of teacher development strategy as a follow-up on teachers’ competency test in Indonesia. The community-based teacher training succeeded in increasing the professionalism of teachers in Indonesia, particularly in terms of implementing their pedagogical and professional competencies. The training is also successful in motivating the teachers to engage themselves in continuous learning efforts through building strong teachers’ network and working collaboratively with colleagues. Quantitatively, training was proven to increase the average of teacher competency by 23.97 (on a scale of 100). The research results are expected to provide information about the best practice in teacher coaching that is conducted massively in a national scope based on the local community so that a lifelong learning culture for teachers is established to support the development of sustainable education.
EFL Teachers’ Cultural Identity Development through Participating in Cultural Negotiation: Probing EFL Students’ Perspectives
Authors: Meihami Hussein , Salīte Ilga 
Published: July 2019

Abstract
This study was an attempt to probe the perceptions of the EFL students about the cultural identity development of the EFL teachers who participated in cultural negotiation programs. To that end, the interactionally oriented narratives of four EFL students were collected. The narratives were about the cultural performance of the EFL teachers who participated in the cultural negotiation programs in the EFL classes. The narratives were codified based on the principles of Strauss and Corbin (1998) systematic approach. the findings indicated that the EFL students had positive opinions about how their teachers dealt with cultural issues in the classrooms after participating in cultural negotiation programs. The findings also indicated that the EFL students perceived that the EFL teachers engaged more in cultural discussions, they used more interaction types, they were more motivated to address cultural issues in the classes, and they took into account the emotions of their students in cultural discussions in the classrooms. Moreover, it can be concluded from the findings that cultural negotiation programs have positive effects on the EFL teachers’ cultural identity development if the principles of identity-as-practice and identity-in-discourse will be followed in the EFL teacher education programs.
Discourse Analysis and Language Pedagogy: A Review
Authors: Bonyadi Alireza 
Published: July 2019

Abstract
Taking discourse approach towards language teaching has been drawing researchers’ and practitioners’ attention since the introduction of discourse analysis as a discipline in social sciences. Based on the premise that education for sustainable development (ESD) in language pedagogy cannot be realized fully unless language teachers are equipped with theoretical issues in discourse analysis, the purpose of this paper is to review the current research on discourse analysis and language teaching. The focus on the intersection of discourse analysis and language education indicates that three approaches, namely Critical discourse analysis, Descriptive discourse analysis, and Pedagogical discourse analysis have been taken by practitioners in educational context. As for directions of future research on discourse analysis and language teaching, it was postulated that the prospective researchers in the field are expected to focus on operationalizing the discourse concepts at the methodological level. This would be possible if EFL/ESL teachers themselves truly get educated in a discourse-based program in teacher education centers.
Experimental versus theoretical study of reverse osmosis pilot scaling: The case of Algerian brackish water desalination
Authors: Bouchareb Abderrezak , Metaiche Mehdi , Lounici Hakim 
Published: July 2019

Abstract
In recent years, the increasing threat to ground water quality due to human activities has become a matter of great concern. The ground water quality problems present today are caused by contamination and by over exploitation or by combination of both. Reverse osmosis (RO) desalination is one of the main technologies for producing fresh water from sea water and brackish ground water.
Algeria is one of the countries which suffer from the water shortage since many years, so desalination technology becomes inevitable solution to this matter.
In this study, a comparison is provided of results of reverse osmosis desalination for three different qualities of brackish water from the central-east region of Algeria (Bouira and Setif Prefectures), wherein they cannot use it as human drinking or in irrigation systems. The main objective of our study is to establish a comparison of the reverse osmosis membrane TW30-2540 performances in the term of (permeate flow, recovery rate, permeate total dissolved solids – TDS and salts rejection) under different operation pressures (each one takes a time of 720 second for pilot scaling). In order to make an overview comparison between the experimental and the simulated results we used ROSA (Reverse Osmosis System Analysis) software.
At the end of this study we noted that, the simulated results are lower than the pilot scaling values and the most removed salts are the sodium chlorides with 99.05% of rejection rate.

Published: July 2019

Abstract
Youth are the change agents of any society, therefore, it is critical to identify their attitudes toward gender roles. The study utilizes a social survey approach, where a stratified random sample is selected from the study population, which consists of Jordanian youth who are enrolled at the University of Jordan in Amman, Jordan. The size of the sample is 848 youth, with 33.5% (N=284) males and 66.5% females (N=564). A survey, based on two scales, is developed to measure youth’s attitudes toward gender roles: the gender professions scale and the gender skills scale. The study also examines the effect of the following variables: age, type of college, place of residence, monthly income, and educational level of the mother. The analysis uses statistical methods to recognize differences in attitudes, to understand the relationship between the independent and dependent variables, and to determine statistical significance (set at p ≤ 0.05). The results show that the attitudes of female youth toward gender roles are nontraditional in comparison to those of their male counterparts. Moreover, attitudes toward gender roles tend to be gender-balanced among older youth who live in urban areas, study in humanitarian colleges, and whose mother’s educational level is high. The study highlights the importance of institutionalizing the concept of gender in higher educational institutions.

The purpose of this text is to demonstrate an operation of a compressed air system designed for high air flow laboratories and wind tunnels. Development of such air system is a challenge due to unusual requirements (simultaneous supply of several users having different requirements and necessity to provide extremely high flows) which have to be address by means of adequate compressed air storage capacity and sophisticated control system. Each stage of the design process is going to be described, focusing on the selection of air compressors, air receivers and air dryers, followed by an insight into a development of the control system. The air system being described in this paper was successfully implemented at the Institute of Aviation in Warsaw improving the quality of the compressed air supply and simplifying the research planning.
Various Types of The Rotorcraft Design in the Context of Aerospace Regulations
Authors: Szafran Krzysztof , Michalczyk Marcin 
Published: July 2019

Abstract
In the next article on synthesis of regulations, the authors presented the general legal requirements for rotorcraft, which is limited to US regulations, because the vast majority of world regulations are based on them. The Institute of Aviation in Warsaw has developed requirements concerning the construction and operation of rotorcraft in Poland. These requirements constitute an important contribution to the regulations of the Civil Aviation Authority which are in force in the air space of the Republic of Poland. This paper presents the legal situation of rotorcraft and compares the requirements for helicopters and gyroplane. The conclusions highlighted the differences that arise from regulations between helicopters and rotorcraft. The authors have suggested the necessity to separate provisions for the group of windmills, which is implemented in the regulations of the Civil Aviation Authority. The presented work is the second of a planned series of publications in which authors intend to bring some of the issues to the reader about the design aspects of aircraft in selected global aviation regulations.
