The paper presents findings from research project Mobis which is aimed at developing a method of assessing safety of unsignalised pedestrian road crossings using video image analysis. Pedestrian and vehicle traffic has been recorded at selected zebra crossing sites in Warsaw and Wrocław, before and after installation of active signage systems SignFlash and Levelite. Speeds of approaching vehicles were measured and drivers’ behaviour was classified using video analysis.
The paper presents a comparison of effectiveness of systems such as SignFlash and Levelite based on changes in the mean and standard deviation of vehicle spot speeds as well as changes in speed profiles of vehicles approaching the crossings.
Results indicate that both SignFlash and Levelite active signage reduce mean vehicle approach speeds and have a positive impact on drivers’ behaviour.
B a c k g r o u n d: Heart failure (HF) is a life-threatening condition which aff ects up to 2% of contemporary populations. Generally, it is a chronic and progressive disease, however in many cases it can be prevented or treated. Nevertheless, effective control of this disease requires awareness of symptoms in the society.
A i m s: The aim of the study was to assess the level of HF knowledge in the Polish population.
M e t h o d s: The questionnaire concerning knowledge about HF prepared by the Competence Network HF under the patronage of the European Heart Failure Association of the ESC, was used. The survey included 534 contributors who formed three groups: medical students — in vast majority at fi rst half of the study course (MS) — 198 (37.1%), HF Awareness Day participants (HFDP) — 134 (25.1%) and other (OP) — 202 (37.8%).
R e s u l t s: Study groups diff ered in terms of gender, age and level of education. As predicted, MS achieved the highest score (22.5 [20.0–24.0]), compared to HFDP (20.0 [17.0–22.0], P <0.001) and OP (19.0 [16.0– 21.0], P <0.001). Knowledge on typical HF symptoms was alarmingly low in the analyzed groups — dyspnea (MS — 96.0%, HFDP — 78.4%, OP — 74.6%), ankle edema (MS — 79.8%, HFDP — 50.6%, OP — 32.2%), body weight gain (MS — 14.1%, HFDP — 17.2%, OP — 4.5%). By multivariate model medical education (β 3.372, 95% CI 2.738–4.005) and own illness or having relatives or friends with HF (β 0.654, 95% CI 0.066–1.242) independently aff ected the score of awareness questionnaire.
C on c l u s i o n s: The basic knowledge on HF in Poland is not sufficient. It is moderately better among MS. Further campaigns improving HF awareness are necessary.
The noise perceiving issue is very subjective and depends on several factors, such as: the living environment in which each person has grown and developed, the education they have received, the culture in which their life principles have formed and, last but not least, the social and financial status. Therefore, in order to establish effective actions in multiple directions when it comes to any urban noise analysis, it is very important to know the perception and the subjective reactions of the individuals involved. The paper respects this idea, presenting the results of a sociological study on urban noise, applied in the city of Cluj-Napoca, Romania. The intention was to capture the reactions of the permanent residents of the city, but also of the people in transit, as well as to analyse the changes that occurred as result of the implementation of the Environmental Noise Directive (European Commission). The study shows that 75.2% of the respondents consider that the noise in the city has increased in the last ten years and 58% of them have rated the noise as level 4 or 5 on a five point scale. Information related to noise maps and actions taken to reduce community noise has no sufficient dissemination. There is also a medium to low reaction of the population in correlation to the declared noise annoyance.
The article analyses the results of mass survey conducted in the framework of the project of the Volkswagen Foundation “Bi- and multilingualism between intensification of conflict and conflict resolution. Ethno-linguistic conflicts, language politics and contact situations in post-Soviet Ukraine and Russia”. Research’s aim was to understand to what extent the state language policy in the area of mass media and cultural sphere meet the expectations of the citizens of Ukraine. It underlines regionally marked attitude towards the strategy of language policy: the Western part of the country prefers Ukrainian language, South – Russian, and Center and North take intermediate positions.
The collapse of the Soviet Union was the cause of a significant decline in many economies of the newly created countries. However, many of them, including the Ukrainian economy, are slowly recovering. One of the largest branches of the economy in this country is construction, which, despite political turmoil, is constantly growing, especially in the private real estate development sector. Despite the fact that the construction market is constantly developing, it is limited by the costs of rework and alterations resulting from many reasons. The key negative effects of modifications to the results of the project are exceeding the budget and time of project implementation, dissatisfaction with the project team, violation of contractual requirements and lowering the quality of the final product. Therefore, the purpose of this article was to determine the reasons for the emergence of rework in the in Ukraine by analyzing the results of surveys conducted among construction enterprises.
The assessment of teachers' exposure to noise in primary schools was carried out on the basis of: questionnaire studies (covering 187 teachers in 3 schools), noise measurements at the teachers' workplaces, measurements of the school rooms acoustic properties (reverberation time and speech transmission index STI in 72 classrooms), analysis of statistical data regarding hazards and occupational diseases in the education sector. The studies have shown that noise is the main factor of annoyance in the school environment. Over 50% of questioned teachers consider noise as annoying and near 40% as very annoying or unbearable. A-weighted equivalent continuous sound pressure levels measured in classrooms, teacher rooms and common rooms are in the range of 58-80 dB and they exceed 55 dB (criteria of noise annoyance). The most frequently reported subjective feelings and complaints (over 90%) are: growth of psychical and emotional tension, irritation, difficulties in concentrating, hoarseness, cough. Noise in schools is also a harmful factor. High A-weighted equivalent continuous sound pressure levels ranging from 80 to 85 dB, measured in corridors during pauses and in sports halls, can cause the risk of hearing damage among PE teachers and persons oversensitive to noise. The latter concerns both teachers and pupils. High background noise levels (55-65 dB) force teachers to raise their voice. It can lead to the development of an occupational disease - chronic voice disorders due to excessive vocal effort lasting for at least 15 years. In the education sector 785 new cases of this disease were reported only in 2008. Poor acoustics in classrooms (reverberation time ranging from 0.8 to 1.7 s, STI < 0.6 in 50% of classrooms) have an adverse influence on speech reception and make the teaching and learning processes difficult.
An important aspect in assessing noise in urban agglomerations is the subjective one, which takes into account the sensitivity and specific reactions of residents to the noise in their living environment. This paper presents results of a sociological study initiated to determine the population awareness, regarding the urban acoustic environment and estimation of effects and disturbance. The survey was conducted in a Romanian city, to complement the information provided by the strategic noise map of the area. This approach allows the estimation of specific local patterns of reaction and response to urban noise of the exposed population and provides the information, needed to develop action plans and to set proper solutions for urban area planning.
Phytophthora citricola was isolated from diseased seedlings of European beech and Silver fir taken from the most of surveyed nurseries. Fusarium species, Pythium ultimum and Rhizoctonia solani were also found in diseased plant tissues.Isoates of P. citricola fro mboth plants and additionally from heather and rhododendron colonised leaf blades, needles and stem parts of beech and fir. In greenhouse trials on inoculated 1-year-old seedlings necrosis spread about 2 mm/24 hr on beech stems whereas on fir about 1.5 mm/24 hr.
Cephus fumipennis Eversmann is a key insect pest of wheat crops in Qinghai, China. Its field population densities were surveyed by using both the back-loaded insect vacuum and a sweep net. Mean densities in township-level were calculated and a quantitative relation, ŷ = 0.664 + 0214x, was established between the two sampling methods. The empirical relationship may be applicable in density monitoring and Integrated Pest Management program of the insect.

In order to assess the challenges and needs of Austrian companies with respect to current
business and technological developments, a regular well-researched compilation of empirical
data of the Austrian manufacturing industry is necessary. Hence, a panel of 104 decisionmakers
(owners, CEOs, managing directors and plant managers) from leading Austrian
industrial companies was assembled in form of an “industry panel” to investigate current
issues of production work in Austria by means of a survey.
In order to allow for a longitudinal study, it is planned to survey the same group of people
every year; hence the instrument of an annual panel-survey was chosen. To date the panel
consists of 104 leaders from different Austrian or international companies with at least one
factory location in Austria. The panel was assembled first in 2018/2019 and the administered
survey contained 23 questions. The actual questions comprise topics that concern the current
economic situation and future expectations, operational issues with respect to delivery
time, product variability and demand fluctuations, as well as questions relating to innovation,
automation and the application of current technological developments (i.e. assistance
systems, machine learning, etc.) in manufacturing. This paper presents the survey results
and conclusions of the 2019 panel on production work in Austria.
Coal mining is one of the most important sectors of the Polish industry. It can be said that the coal is a national raw material. This results in Poland being a pioneer in the European Union in terms of coal mining as well as its use in the production of electricity and heat. There are many companies in Poland which have been established and developed around the coal mining industry aimed at coal extracting. The operations of those companies depends on the condition of the mining companies and their cooperation with them: commercial, service and advisory, called referred to as “mining supporting companies”. The article focuses on the results of a survey carried out in mining supporting companies, such as mining machinery and equipment manufacturers, mining-related service companies and mining-related research and development institutions. The authors evaluated the relationship and dependence of those companies on the mining industry. It was assumed that the measure of the mining supporting companies condition is the overall quantity of public related payments contributed to the state budget and local budgets. In the article, the authors raised the problem of the size of losses for public finances, as a result of the significant limitations of financial flows from the mining companies. The surveyed companies are those associated with the Polish Mining Chamber of Industry and Commerce. As a result, the authors prepared conclusions regarding the dependence of the mining supporting companies on the situation of the mining subsector.
The authors draw on their experience and past mountain landscape studies to describe an emerging collaborative research project designed to conduct advanced field studies and generate (and test) archaeological landscape models of past hunter-gatherer populations as well as pastoralist and early farming community seasonal transhumance migrations between lowland river valleys of Poland’s Podhale Basin and high altitude forests and meadows its adjacent High Tatra Mountains.
Present study examines nonfinancial support granted for older people in Poland and other European countries in order to understand the relationships between family structures and that support and to diagnose the challenges that the Polish population may face in this respect in the nearest future. The analysis is based on the data from the Survey on Health, Aging and Retirement in Europe (SHARE). The study attempts also to answer the question about the need for informal support in future generations of older Poles. The study is focused on the population of individuals aged at least 50+, because they will decide about the situation of older people in the near future. The author considers, in addition to personal care, help in running a household and help with paper work. The most frequently received type of support is the help in running a household, received primarily from neighbors and family members, which reduces the need for institutional care. Personal care is provided to the minority of the examined population, even in the highest age group, and, apart from household members, it concerns usually biological children.
