The aim of the paper was to diagnose and analyse the rates of infections in Polish voivodships, and possible consequences from both economic and social perspectives of the changes in the levels of cases reported. For the analyses, data banks of Central Statistical Office in Warsaw were used, in particular, information on the incidence of infectious diseases and poisonings. The rates of changes and spatial concentration of the phenomena were investigated in the period between 2005 and 2015. For estimates of regional trends, the Shift-Share Analysis was adopted, and the pattern of spatial distribution was defined on the basis of location quotients. Extreme values of location quotients were observed in Warmińsko-Mazurskie for shigellosis, in Lubuskie for trichinellosis, and for AIDS in Dolnośląskie. Location quotient values allowed identifying regions with a higher spatial concentration of infectious diseases incidences, which in turn could indicate areas and cases where preventive actions should be improved or modified. The Shift-Share Analysis resulted in pointing out regions that recorded a positive change in infection rates. The obtained results also demonstrated that in some cases, the impact of structural changes influences the net rates of infections more than the local components. The obtained results directly indicated objects (regions) where attention should be paid to prevention. Especially, the results of spatial distribution and concentration allowed a reliable analysis of the state of population incidence rates, as well as answered questions concerning the origin of rates whether the change derived from structural, local or overall tendencies. Results could be adopted, for instance, in preventive strategies of local governments. The estimates might be beneficial from the perspective of the healthcare system, due to easier predictive scenarios of future infection and possible centres with the increase in incidence.

PL

Zarządzanie logistyczne, można rozumieć, jako procesowe podejście do organizacji, czyli składowe takich elementów, jak gromadzenie, przepływ, monitorowanie i transport dóbr i usług. Zarządzanie logistyczne odpadami medycznymi, opiera się na zasadach, działaniu i podziale, jakim rządzi się logistyka, ale w odniesieniu do służby i ochrony zdrowia. Artykuł ukazuje cele logistycznego zarządzania odpadami medycznymi, jak również podział tego typu odpadów, przez WHO, przepisy prawne uregulowane w odpowiednich ustawach, jak również HCF. Dodatkowo w artykule poruszono tematykę gromadzenia i przechowywania odpadów oraz ich późniejszego transportu z podziałem na dwa rodzaje transportu – zewnętrzny i wewnętrzny. Ponadto autorzy artykułu umieścili w nim zagadnienia dotyczące kosztów transportu odpadów medycznych, wraz ze wzorem i objaśnieniem dotyczącym jego obliczenia

EN

Logistics management, may be interpreted as a process-based approach to the organization, or components of such items as collecting, flowing, monitoring and transport of goods and services. Logistics management of medical waste, is based on principles, operation and division, which is governed by logistics, but in relation to services and health care. Article outlines the objectives of the logistics management of medical waste, as well as division of type of waste, by WHO, regulations governed by relevant laws, as well as HCF. In addition, the paper raised subject of the collection and storage of wastes and their subsequent transport by two types of transport - internal and external. In addition, the authors of the article put it issues concerning costs of medical waste transport, along with the model and explanation on his calculations.

Konsultacje społeczne w zakresie gospodarki mieszkaniowej na przykładzie Łodzi

wiele, o tyle w odniesieniu do odpowiedzialności władz miasta już nieco mniej. Przykładem na zastosowanie koncepcji społecznej odpowiedzialności zarządzających miastem może być Łódź (miasto na prawach powiatu), która za pomocą konsultacji społecznych stara się poznać zdanie mieszkańców w niezwykle kluczowych kwestiach dotyczących ich samych. Jednym z takich kluczowych obszarów jest gospodarka mieszkaniowa, która powinna być szczególną domeną zainteresowań władz, za co w tym względzie władza ta powinna być odpowiedzialna. Warto w tym miejscu wyjaśnić, czym jest CSR i gdzie można je umiejscowić w procesie zarządzania. CSR, czyli społeczna odpowiedzialność biznesu, to termin oznaczający koncepcję, na podstawie której, podczas tworzenia strategii działania uwzględnia się interesy społeczne, ochronę środowiska, etykę, jak również relacje z interesariuszami. Ma to swój wydźwięk w postaci realnych wpływów na skuteczność działalności gospodarczej organizacji, która zastosowała CSR.

One of the expressions of concern for the interests of local communities is the activity of the local community in the area of social, economic and cultural. Possibility of influencing the matter of a county, municipality or city reveals, among other things: the participation of the citizens of the community in public consultations, which are a dialogue with the authorities in the region. Example of the common objectives, and for the first time the city of Lodz citizens’ participation were public consultations in the development of Housing Policy in the city of Lodz 2020+. The purpose of this article is to pay attention to the nature of dialogue between the community and its residents, and the role of public consultation in an effort to improve the quality of life.

On the approximation theorem of Wong-Zakai type for the Lasota operator

We consider in this paper a stochastic evolution equation with Professor A. Lasota's operator as the infinitesimal generator of a strongly continuous semigroup of transformations and with Hammerstein operator connected with a noise being the Wiener process. We show that such evolution equation satisfies the Wong-Zakai type approximation theorem. The idea of the definition of the Lasota operator has the origin in the mathematical model of the creation and differentiation of cells in biology and medicine.

The aim of the paper is to examine the wavelet-Galerkin method for the solution of filtering equations. We use a wavelet biorthogonal basis with compact support for approximations of the solution. Then we compute the Zakai equation for our filtering problem and consider the implicit Euler scheme in time and the Galerkin scheme in space for the solution of the Zakai equation. We give theorems on convergence and its rate. The method is numerically much more efficient than the classical Galerkin method.

W pracy pokazano, że stochastyczne równanie ewolucyjne z operatorem Lasoty jako infinitezymalnym generatorem silnie ciągłej półgrupy odwzorowań i z operatorem Hammersteina występującym przy zaburzeniu będącym procesem Wienera, spełnia twierdzenie aproksymacyjne typu Wonga-Zakai. Idea wprowadzenia operatora Lasoty związana jest z matematycznym modelem powstawania i różnicowania się komórek.

We prove a support theorem for a stochastic version of the Burgers system formulated for the deterministic case by Burgers in [Bu 39]. The existence and uniqueness theorem for such a stochastic system was given by Zabczyk and Twardowska in [TZ 06]. In the proof of our support theorem we use a Wong-Zakai type theorem for such a system proved by Nowak in [No 05]. We generalize the method of Mackevicius ([Ma 85]}, [Ma 86]) and Gyongy ([Gy 89]) to prove the support theorem for our stochastic system of Burgers equations. We also use some considerations from Twardowska [Tw 97a]. In our proof of the invariance theorem we use some result of Jachimiak from [Ja 98].

A nonlinear filtering problem with delays in the state and observation equations is considered. The unnormalized conditional probability density of the filtered diffusion process satisfies the so-called Zakai equation and solves the nonlinear filtering problem. We examine the solution of the Zakai equation using an approximation result. Our theoretical deliberations are illustrated by a numerical example.
