This study evaluated the process of in-site sorting of the generated solid waste (SW) in some educational institutions in Ma’an city, Jordan. The study included eight schools and one University. The students and employees of seven schools, as well as the students and employees of the University, had received the awareness campaigns concerning the importance and benefits of in-site sorting of SW. As a control, one school student and employee who had not received awareness campaigns were involved. The institutions were provided with four bins at each collection site (glass and plastic, paper and cardboard, metals, and bread). The content of bins in each institution was collected and sorted manually to evaluate the efficiency of the conducted awareness campaigns on onsite sorting behavior. The mass ratios of many SW components in their designated bins in the reference school (control) were higher than the average ratios in the assigned bins for the same component in all schools. As for the University, the results of the manual sorting showed that all bins included a mix of SW in different ratios; moreover, the proportions of glass and plastic, and metals were lower than the proportions of other components. On the basis of the above mentioned results, it can be concluded that the awareness campaigns did not achieve the stated goals; subsequently, the in-site sorting failed in the schools and the University. Thus, different awareness campaigns should be assessed to identify the best approach positively affect the SW sorting and disposal habits of people.

Celem artykułu jest prezentacja metodycznego podejścia w obszarze doskonalenia bezpieczeństwa placówki oświatowej, które zostało przeprowadzone w jednej ze szkół województwa wielkopolskiego. W 11 sekwencyjnie zrealizowanych etapach procesu badawczego wzięła udział społeczność szkolna. Bodźcem dla omawianego przedsięwzięcia było zaobserwowanie przez autorów artykułu stanu stagnacji w działaniach na rzecz bezpieczeństwa. Na podstawie wywiadu swobodnego w gronie pedagogicznym oraz utrzymywanych zapisów w dokumentacji szkolnej dotyczącej bezpieczeństwa szkoły wskazano na duże rozbieżności w ocenie stanu rzeczy. Zidentyfikowane problemy powiązano z powszechnie sygnalizowaną postawą braku osobistej odpowiedzialności za wspólne bezpieczeństwo, głównie w grupie uczniów. Zainicjowało to podjęcie działań w celu poprawy bezpieczeństwa z wykorzystaniem środków komunikacji interpersonalnej. Ponieważ zaangażowanie jest kluczem do sukcesu, dlatego położono nacisk na współpracę wszystkich podmiotów uczestniczących w funkcjonowaniu placówki oświatowej, tj.: uczniów, grona pedagogicznego, rodziców, pracowników administracyjnych oraz pracowników technicznych, w ciągłym doskonaleniu, które jest częścią kultury organizacji. Chcąc wzmocnić efekt oddziaływania komunikowanej informacji związanej z bezpieczeństwem społeczności szkolnej, przyjęto wytyczne w doborze środków techniczno-organizacyjnych, które wzmacniają siłę przekazu.

The aim of the article is to present a methodical approach to improving the safety of an educational institution, which was carried out in one of the schools in the Greater Poland Voivodeship. The entire school community was covered in ten sequentially implemented stages of the research process. The stimulus for the discussed undertaking was the author’s observation of the state of stagnation of activities related to safety. On the basis of a free interview with a group of teachers and on the basis of records maintained by the school regarding school safety, large discrepancies in the assessment of the state of affairs were indicated. The identified problems were related to the commonly signaled attitude of a lack of personal responsibility for common safety, mainly in the group of students. This initiated taking actions to improve safety with the use of interpersonal communication means. Since commitment is the key to success, emphasis was placed on the continuous improvement of the cooperation of all entities participating in the functioning of educational institutions, i.e. students, teaching staff, parents, administrative employees and technical employees, which is part of the organizational culture. In order to strengthen the effect of the communicated information related to the safety of the school community, guidelines were adopted in the selection of technical and organizational measures that strengthen the power of communication.

Many old public buildings in Central and Eastern Europe are characterized by low energy efficiency and often lack of mechanical ventilation. The general trends are aimed to improve the energy efficiency of the building sector and to provide comfort conditions. The indoor air quality can be determined based on the CO2 concentrations. In the article, a complex approach to the definition and analysis of data on the indoor CO2 concentration and the air exchange rate in educational institutions at natural air exchange and in the absence of mechanical air circulation was implemented. Educational institutions in Kyiv have been considered. The study of the CO2 concentration of indoor and outdoor air of three typical schools of mass development in the 80 s, as well as the training building of Igor Sikorsky KPI, was carried out. Experimental determination of the background CO2 concentration during the day next to the considered objects showed that the background concentration of CO2 is in the range of 400-420 ppm. Measurements of the CO2 concentration distribution were carried out after classes throughout the classroom area, according to which the difference between the values at the level of the working area was 30...180 ppm. It was found that the concentration of CO2 varies during classes between 700-1100 ppm. During the break, the CO2 concentration decreases to 500-1000 ppm, depending on the type of ventilation. Experimental data on the dynamics of changes in the indoor CO2 concentration are used to determine the air exchange rate based on balances of air flows and CO2. It is shown that the number of present persons influences the indoor CO2 concentration more significantly than the air exchange rate. On the example of an experimental study of the CO2 concentration in the classrooms for high school students it was found that the air exchange rate during the classes is in the range of 0.4...0.75 h-1. During breaks the air exchange rate increases to 2.9-3.5 h-1. For the range considered, the weighted average air exchange rate is 0.8 h-1, and even with forced airing, the air exchange rate is insufficient to ensure acceptable CO2 concentration. For the training building of Igor Sikorsky KPI a field experiment was carried out to determine the dynamics of changes in CO2 concentration in time and on the basis of it the air exchange rates for representative classrooms were determined. The concentration of CO2 ranged from 500 to 2000 ppm and increases by 350-850 ppm depending on the use and location of classrooms. Based on experimental data, the air exchange rate for the training building of the education institution is in the range of 0.35-0.7 h-1. During the periods of airing the air exchange may increase by 0.45 h-1, but this does not allow reaching the standard value. When analyzing the obtained results, simulation models of natural air exchange of the examined classrooms were used on the basis of the improved ASHRAE method. The natural air exchange rate based on simulations is in the -0.8…0.5 h-1 range. Negative values are explained by exfiltration, which is typical for the upper floors. Not only the comfort and condition of the building envelope, but also the total energy consumption of the building depend on the actual level of air exchange rate. In the total energy balance the ventilation component is 30-60%. Further use of the obtained results can be connected with monitoring of the actual level of air exchange rate and its consideration during complex modernization or implementation of the ventilation systems with heat recovery in the premises of educational institutions.
