Opis:
Air pollution is the reason for huge damages to European Union citizens’ health. Every year, some 400,000 Europeans die prematurely as a result of excessive levels of such substances as suspended dust, nitrogen dioxide and ozone. It is despite the fact that the EU legal regulations on the permissible values of air pollutants have been in force for almost thirty years. In order to broaden the knowledge of air pollution as well as the ways to implement and the effectiveness of the policy on air protection in individual Member States, the Supreme Audit Office and the Netherlands Court of Audit coordinated the largest international audit in the field of environmental protection in the history of the European Organisation of Supreme Audit Institutions – EUROSAI. The audit resulted in a joint audit report on air quality, based on the findings of the audits conducted in the countries that participated in this project.

Opis:
A review of the known and an indication of the new threats for cyber-physical robotic systems, caused by cybernetic attacks, serves, in this paper, as a basis for the analysis of the known methods relied upon to detect and mitigate consequences of such attacks. A particular emphasis is placed on threats specific for cyber-physical systems, as they are a feature distinguishing these systems from their traditional Information and Communication Technologies (ICT) counterparts. Based on the review of literature and own analyses, unresolved issues regarding the cyber-security of robot systems are presented and discussed.

Opis:
Social robots’ software is commonly tested in a simula‐ tion due to the safety and convenience reasons as well as an environment configuration repeatability assurance. An interaction between a robot and a human requires ta‐ king a person presence and his movement abilities into consideration. The purpose of the article is to present the HuBeRo framework, which can be used to simulate hu‐ man motion behaviour. The framework allows indepen‐ dent control of each individual’s activity, which distinguis‐ hes the presented approach from state‐of‐the‐art, open‐ source solutions from the robotics domain. The article presents the framework assumptions, architecture, and an exemplary application with respect to presented sce‐ narios.

Opis:
Ten dwuczęściowy artykuł przedstawia interfejs do Narodowej Platformy Cyberbezpieczeństwa (NPC). Wykorzystuje on gesty i komendy wydawane głosem do sterowania pracą platformy. Ta część artykułu przedstawia strukturę interfejsu oraz sposób jego działania, ponadto prezentuje zagadnienia związane z jego implementacją. Do specyfikacji interfejsu wykorzystano podejście oparte na agentach upostaciowionych, wykazując że podejście to może być stosowane do tworzenia nie tylko systemów robotycznych, do czego było wykorzystywane wielokrotnie uprzednio. Aby dostosować to podejście do agentów, które działają na pograniczu środowiska fizycznego i cyberprzestrzeni, należało ekran monitora potraktować jako część środowiska, natomiast okienka i kursory potraktować jako elementy agentów. W konsekwencji uzyskano bardzo przejrzystą strukturę projektowanego systemu. Część druga tego artykułu przedstawia algorytmy wykorzystane do rozpoznawania mowy i mówców oraz gestów, a także rezultaty testów tych algorytmów.
This two part paper presents an interface to the National Cybersecurity Platform utilising gestures and voice commands as the means of interaction between the operator and the platform. Cyberspace and its underlying infrastructure are vulnerable to a broad range of risk stemming from diverse cyber-threats. The main role of this interface is to support security analysts and operators controlling visualisation of cyberspace events like incidents or cyber-attacks especially when manipulating graphical information. Main visualization control modalities are gesture- and voice-based commands. Thus the design of gesture recognition and speech-recognition modules is provided. The speech module is also responsible for speaker identification in order to limit the access to trusted users only, registered with the visualisation control system. This part of the paper focuses on the structure and the activities of the interface, while the second part concentrates on the algorithms employed for the recognition of: gestures, voice commands and speakers.

Opis:
Objectives: The aim of this study was to evaluate the coexisting factors and usefulness of diagnostic methods in metal-induced asthma in Polish welders. Materials and Methods: Examination of 50 welders occupationally exposed to metals and with suspicion of metal-induced asthma (group A), 100 welders occupationally exposed to metals but without suspicion of metal-induced asthma (group B), and two control groups (10 patients with atopic asthma and 10 healthy subjects) was carried out. Questionnaire survey, clinical examination, skin prick tests to common aeroallergens and metal salts, rest spirometry tests, X-ray, metacholine challenge and a single-blind, placebo controlled specific inhalation challenge tests with metals (or work-like conditions challenge tests) were performed. Results: In group A – in 9 cases we obtained positive results of specific inhalation challenge tests with metals (in 3 cases with nickel, in 4 cases with chromium, in 1 case with cobalt and in 1 case with manganese). Nine cases of metal-induced occupational asthma were recognized. In group B – only in one case we obtained positive results of work-like conditions challenge test (clinical and spirometry changes, eosinophil influx in induced sputum), which confirmed the diagnosis of occupational asthma. In most of examined welders (62%), pulmonary changes in chest X-ray images were noted. The statistical analysis revealed that working as a welder for more than 10 years is the coexisting factor of presence of chest X-ray changes (p- or q-type nodular changes or interstitial changes). Positive results of skin prick tests with metal salts were the coexisting factors of occupational asthma due to metals among examined group of welders. Conclusions: Specific inhalation challenge plays the key role in diagnostics of metal-induced asthma in welders. Pulmonary changes in chest X-ray were found in a significant percentage of examined welders.

Opis:
Objectives About 5–10% of asthmatics do not respond well to standard treatment plan. Occupational exposure may be one of the factors that can be linked with treatment failure. The aim of the study was to assess the prevalence of work-related asthma (WRA) among adult asthmatics under follow up in an outpatient allergy clinic and to create a useful tool for detecting individuals with possible WRA. Material and Methods Preliminary 5-question questionnaire designed to recognize WRA was presented to 300 asthmatics. All patients with positive preliminary verification along with 50 subjects from control group were asked to fill up a detailed questionnaire. The WRA was diagnosed by positive match for asthma symptoms in combination with workplace exposure indicated in the detailed WRA questionnaire followed by confirmation of each WRA case by detailed exposure analysis. Results Work-related asthma was recognized in 63 subjects (21% of study group). The preliminary questionnaire has 76.9% sensitivity and 94% specificity in recognition of WRA. Occupational exposure to irritants is a risk factor of WRA recognition (relative risk (RR) = 2.09 (1.44:3.03)). Working in exposure-free environment is a factor against WRA recognition (RR = 0.38 (0.24:0.61)). Among subjects with work-related asthma, the uncontrolled course of the disease is significantly more frequent (p = 0.012). Subjects with WRA more often report sickness absenteeism due to asthma than those without WRA (9.6% vs. 3.2%, respectively), but the observed differences did not reach the statistical significance. Conclusions Short 5-question questionnaire seems to be a promising tool to detect individuals with possible work-related asthma in the outpatient setting for further evaluation and additional attention.

Opis:
Objectives The aim of the study was to evaluate health effects of occupational exposure to diisocyanates (DIC) among polyurethane foam products factory workers. Material and Methods Thirty workers had a physical examination, skin prick tests with common allergens, allergen-specific immunoglobulin E (IgE) antibodies to diisocyanates and pulmonary function tests. Concentrations of selected isocyanates in the workplace air samples as well as concentration of their metabolites in the urine samples collected from the workers of the plant were determined. Results The most frequent work-related symptoms reported by the examined subjects were rhinitis and skin symptoms. Sensitization to at least 1 common allergen was noted in 26.7% of the subjects. Spirometry changes of bronchial obstruction of a mild degree was observed in 5 workers. The specific IgE antibodies to toluene diisocyanate (TDI) and 4,4’-methylenebis(phenyl isocyanate) (MDI) were not detected in any of the patients’ serum. Cellular profiles of the collected induced sputum (ISP) did not reveal any abnormalities. Air concentrations of TDI isomers ranged 0.2–58.9 μg/m³ and in 7 cases they exceeded the Combined Exposure Index (CEI) value for those compounds. Concentrations of TDI metabolites in post-shift urine samples were significantly higher than in the case of pre-shift urine samples and in 6 cases they exceeded the British Biological Monitoring Guidance Value (BMGV – 1 μmol amine/mol creatinine). We didn’t find a correlation between urinary concentrations of TDI, concentrations in the air and concentrations of toluenediamine (TDA) in the post shift urine samples. Lack of such a correlation may be an effect of the respiratory protective equipment use. Conclusions Determination of specific IgE in serum is not sensitive enough to serve as a biomarker. Estimation of concentrations of diisocyanate metabolites in urine samples and the presence of work-related allergic symptoms seem to be an adequate method for occupational exposure monitoring of DIC, which may help to determine workers at risk as well as to recognize hazardous workplaces.
