In the last years, many studies have focused on risk assessment of exposure of workers to airborne particulate matter (PM). Several studies indicate a strong correlation between PM and adverse health outcomes, as a function of particle size. In the last years, the study of atmospheric particulate matter has focused more on particles less than 10 μm or 2.5 μm in diameter; however, recent studies identify in particles less than 0.1 μm the main responsibility for negative cardiovascular effects. The present paper deals with the determination of 66 organic compounds belonging to six different classes of persistent organic pollutants (POPs) in the ultrafine, fine and coarse fractions of PM (PM < 0.1 µm; 0.1 < PM < 2.5 µm and 2.5 < PM < 10 µm) collected in three outdoor workplaces and in an urban outdoor area. Data obtained were analyzed with principal component analysis (PCA), in order to underline possible correlation between sites and classes of pollutants and characteristic emission sources. Emission source studies are, in fact, a valuable tool for both identifying the type of emission source and estimating the strength of each contamination source, as useful indicator of environment healthiness. Moreover, both carcinogenic and non-carcinogenic risks were determined in order to estimate human health risk associated to study sites. Risk analysis was carried out evaluating the contribution of pollutant distribution in PM size fractions for all the sites. The results highlighted significant differences between the sites and specific sources of pollutants related to work activities were identified. In all the sites and for all the size fractions of PM both carcinogenic and non-carcinogenic risk values were below acceptable and safe levels of risks recommended by the regulatory agencies.

During the work on the draft of the 1997 Code of the Execution of Penalties (CEP) much attention was paid to the principle of the treatment of sentenced persons, and particu-larly those serving prison sentences, as subjects. In the Polish penological literature two dimensions of that principle were indicated. The first one referred to the strengthening of the sentenced person’s position in relation to enforcement authorities by means of precise regulations concerning his/her legal status and effective mechanisms for the protection of his/her rights. The second dimension meant the abandonment of forced rehabilitation and providing sentenced persons with the ability to decide freely whether they wanted to partici-pate in correctional interventions. Undoubtedly, the 1997 CEP strengthened the legal status of a sentenced person. As regards the abandonment of forced rehabilitation, the legislator chose a compromise solution according to which the participation in correctional interven-tions was, as a rule, voluntary, but in some cases it was mandatory. Like in other countries, in Poland in the last decade the idea of the public protection against crime played an in-creasingly important role in the criminal policy. In the criminal justice system focused on risk management, the treatment of sentenced persons as subjects requires providing them with reliable information on the possible consequences of their decisions concerning the participation in offered correctional activities. Additionally, it requires providing them with adequate access to empirically proven correctional programmes as well as introducing a transparent system of risk assessment and monitoring during the execution of the imposed penalty or penal measure.

The sustainability and profitability of fresh produce supply chains are contingent upon several risk factors. This work, therefore, examines several risk indicators that affect the quality and safety of fresh produce in transit, including technological, biological, sustainability, environmental, and emergency risks. Then, we developed a risk assessment and monitoring model that employs a machine learning algorithm, a support vector machine, based on historical monitoring data. The proposed methodology was then applied to simulation and numerical analysis to assess the risks incurred in the strawberry cold chain. After training, the algorithm predicted the risks incurred during transportation with an average accuracy of 90.4%. Therefore, the developed methodology can effectively and accurately perform a risk assessment. Furthermore, the risk assessment model can be applied to other fresh produce due to comprehensive risk indicators. Decision-makers in fresh produce logistics companies can use the developed methodology to identify and mitigate risks incurred, thus improving food safety, reducing product loss, maximizing profits, and realizing sustainable development.

PT. Transjakarta is a transportation company that uses an electronic ticket system. The ticket system at the Transjakarta bus stop since 2013 uses an electronic card (e-ticketing), instead of cash. One of these cards is the Flazz card issued by Bank BCA. However, the cash deposit from the sale of the flazz top up from Transjakarta to Bank Bca still experiences constraints, there is a difference every day. Then the need for internal control in the payment process and reconciliation between Bank Bca billing data and top up cash payments in the Transjakarta. So far the two reports that should have been balanced, in fact never happened. That is why reconciliation is needed and the causes of the differences are sought so that a balanced report can be produced. This study aims to determine the implementation of internal control on the concept of components according to COSO. The author uses descriptive methods with the type of qualitative analysis, by reviewing the application of elements of internal control by describing the facts that exist in the field, and analyzing the application of these elements with reference to COSO. The results show that in general the internal controls applied for top up flazz payments have met and are in accordance with the concepts and principles of internal control according to COSO. However, the implementation of the concept of internal control components needs to be refined to be more effective, namely the environmental control, risk assessment and monitoring components.
