Ventilation Performance

For students, who spend most of their time in school classrooms, it is important to maintain indoor air quality (IAQ) to ensure a comfortable and healthy life. Recently, the ventilation performance for indoor air quality in elementary schools has emerged as an important social issue due to the increase in the number of days of continuous high concentrations of particulate matter. Three-dimensional numerical analysis has been introduced to evaluate the indoor airflow according to the installation location of return diffusers. Considering the possibility of the cross-infection of infectious diseases between students due to the direction of airflow in the classroom, the airflow angles of the average respiratory height range of elementary school students, between 1.0 and 1.5 m, are analyzed. Throughout the numerical analysis inside the classroom, it is found that the floor return system reduces the indoor horizontal airflow that causes cross-infection among students by 20% compared to the upper return systems. Air ventilation performance is also analyzed in detail using the results of numerical simulation, including streamlines, temperature and the age of air.

Shame And Guilt

Abstract In the processual approach to identity, the role of the interaction between subjective and contextual factors in the process of its development is emphasized. Based on the model of Luyckx et al. (2008) relationships between identity and educational context, as well as the tendency to experience shame and guilt were analyzed.. 821 people aged from 14-25 and belonging to six educational groups: (1) lower secondary school, (2) basic vocational school, (3) technical upper secondary school, (4) general upper secondary school, (5) post-secondary school (medical rescue, massage therapy, cosmetology, occupational therapy) and (6) university, took part in the research. Two questionnaires were used: The Dimensions of Identity Development Scale (DIDS), to allow the measurement of the five dimensions of identity postulated by Luyckx et al (2008) and The Personal Feelings Questionnaire-2 (PFQ-2, Harder, Zalma, 1990) to measure of the shame and guilt proneness. The results show that general upper secondary school students in terms of the dimensions of identity are closer to lower secondary school students rather than to their peers from technical and vocational schools. Among general upper secondary school students not only was a higher intensity of an identity crisis observed, but also a strong tendency to experience shame and guilt. Among lower secondary school students and general upper secondary school students, people with diffusion and moratorium as identity statuses prevailed, while in the remaining groups the achievement and foreclosure identity were observed more frequently. A general relationship was also observed, namely, a greater tendency to experience shame was associated with a higher intensity of an identity crisis.

Simulation Results

Recently, attention has been given to indoor air quality due to its serious health concerns. Clearly the dispersion of pollutant is directly affected by the airflow patterns. The airflow in indoor environment is the results of a combination of several factors. In the present study, the effects of thermal plume and respiration on the indoor air quality in a ventilated cubicle were investigated using an unsteady computational modeling approach. The person-to-person contaminant transports in a ventilated room with mixing and displacement ventilation systems were studied. The effects of rotational motion of the heated manikins were also analyzed. Simulation results showed that in the cases which rotational motion was included, the human thermal plume and associated particle transport were significantly distorted. The distortion was more noticeable for the displacement ventilation system. Also it was found that the displacement ventilation system lowered the risk of person-to-person transmission in an office space in comparison with the mixing ventilation system. On the other hand the mixing system was shown to be more effective compared to the displacement ventilation in removing the particles and pollutant that entered the room through the inlet air diffuser.

The Impact

Science education in Rwandan schools still faces a number of challenges including the lack or shortage of equipment available for science experiments. This paper describes research conducted to assess the impact of using improvised versus conventional laboratory equipment in experiments. Eighty-five lower secondary school students were assessed using a semi-experimental post-test design on thermal expansion of bodies. Data analysis using a t-test produced a t-Stat of 2.74 over a t-Critical of 1.98 indicating a statistical significance between the two experimental groups in favour of the group using improvised equipment. As a result, it is recommended that improvised equipment be used in those instances in which there is a lack or shortage of conventional equipment since students’ achievement was similar regardless of the type of equipment used.

The Individual

The paper presents the results of the study on participative mapping of landscape values and conflicts and a subsequent interpretation of the indicated localities from respondents’ point of view. The study focused on younger groups of landscape users—lower-secondary-school students (aged 11–15) and university students (aged 20–25)—in comparison with experts’ points of view. The research presumed that the perception of landscape values and issues are determined by age, level of education and by experience in the field. The study was conducted in the southeastern area of the Czech Republic (49° N, 16° E) via online data collection. Based on the obtained records, we conclude that, in terms of the typology of the valuable and problematic locations, the individual groups of respondents did not differ significantly and the selection of location types was similar across all groups. Lower-secondary-school students rather identified cultural values associated with everyday activities, and the descriptions contained emotional overtones. University students preferred natural values associated with formal values based on general consensus or conflicts associated with society-wide impacts. The experts base served as the benchmark for other groups.
