This study aims to investigate differences and similarities in the approach to understanding university social responsibility (USR) among the academic and university administrative staff.

The quantitative research was conducted on a group of 1,160 respondents from the chosen university. The survey contributes to the discussion about the needs and expectations regarding USR. The data were subjected to reliability verification and statistically tested.

The study revealed that academic and university administrative staff pay attention to different aspects of USR. The differences appear in expectations of the senior and junior academic staff and when scientific disciplines are taken into consideration. It may suggest that not only the level of research performance but also the structure of academic staff can be a driver for corporate social responsibility benefits.

Research results can be helpful for proper designing of socially responsible activities regarding different groups of employees and enable a better understanding of the needs of employees regarding the creation of socially responsible activities at the university.

This study contributes to the literature by presenting the academic and university administrative staff’s attitude towards USR, giving better insights into their expectations and needs. Research findings contribute to the more grounded discussion on the topic and can be used by organizations to set goals and priorities for USR.

The purpose of this paper is to present the varied roles played by the University of Lódz (UL) in maintaining and restoring the natural capital of a city as a driver for sustainable city development. The higher education institution can be perceived as visionary, originator and executor of natural capital projects.

The paper analyses three cases performed by the Faculty of Biology and Environmental Protection, UL, in the city of Lódz. The activities are based on different scales ranging from city-wide to local, e.g. river and green infrastructure, and which vary in character from policy planning to implementation.

Natural capital projects influence city development on different levels: by the initiation of legal protection, by the implementation of rehabilitation concepts for rivers and by influencing the strategic documents for mid-term and long-term urban development.

The university has the potential for multidisciplinary engagement in the development of urban sustainability. In large-scale projects, academics play a more conceptual role, in capacity building and knowledge transfer, while in local-scale implementations, their role includes innovation, know-how and technology transfer. Moreover, it may act as a reinforcement hub, by safeguarding and strengthening the natural capital of the city.

Examines the seventeenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

The main aim of the study was to measure and assess the efficiency of the healthcare system in Poland.

An output-oriented Data Envelopment Analysis model with a 2-years window analysis extension was used between 2013 and 2018. The analysis was completed with a determination of the sources of productivity changes (between the first and last year of the study period) and factors that influence efficiency.

Efficient regions have been identified and the spatial diversity in their efficiency was confirmed. The study identified individual efficiency trends together with “all-windows” best and worst performers. Using panel modeling, it was confirmed that the efficiency of health protection is influenced by, among others, accreditation certificates, the length of the waiting list or the number of medical personnel.

Although the analysis was conducted at the voivodeship level (NUTS2), which was fully justified, it would be equally important to analyze data with a lower aggregation level. It would be extremely valuable from the perspective of difficulties faced by the healthcare system in Poland.

The identification of areas and problems affecting the efficiency of the healthcare system in Poland may also be a hint for other countries with similar system solutions that also struggle with the same problems.

The paper explains the efficiency of the country's healthcare system while also paying attention to changes in its level, factors influencing it, spatial diversity and impact on the sector functioning.

This paper aims to provide the results of investigations concerning an influence of the tyre with longitudinal grooves on the car body aerodynamics. It is considered as an important aspect affecting the vehicle aerodynamic drag.

To investigate a contribution of grooved tyres to the overall vehicle drag, three wind tunnel experimental campaigns were performed (two by Peugeot Société Anonyme Peugeot Citroen, one at the Lodz University of Technology). In parallel, computational fluid dynamics (CFD) simulations were conducted with the ANSYS CFX software to enable formulation of wider conclusions.

The research shows that optimised tread patterns can be derived on a single tyre via a CFD study in combination with a controlled experiment to deliver designs actively lowering the overall vehicle aerodynamic drag.

A reduction in the aerodynamic drag is one of ways to decrease vehicle fuel consumption. Alternatively, it can be translated into an increase in the maximum travel velocity and the maximum distance driven (key factor in electric vehicles), as well as in a reduction of CO₂ emissions. Finally, it can improve the vehicle driving and steering stability.

The tyre tread pattern analysis on isolated wheels provides an opportunity to cut costs of R&D and could be a step towards isolating aerodynamic properties of tyres, irrespective of the car body on which they are applied.

This paper presents an IT system – Student Connectivity Module (SCM) – designed to support administration of student exchange between universities in different countries, developed under the EU seventh Framework Program. The purpose of this paper is to share the acquired knowledge on existing difficulties in mobility management, propose solutions to those problems, and present results of system validation using its prototype deployed at two universities.

Prior to the system design, the needs, plans and expectations concerning the academic IT services were surveyed among 100 universities. On this basis, in close with prospective system users, an original peer-to-peer system was developed using top-down model-driven and agile software development techniques.

The barriers to effective interoperation of academic information systems (AIS) were revealed: first, diversity and heterogeneity of campus IT solutions; second, differences in patterns of international student mobility flow; third, diversity in national personal data protection policies; and fourth, lack of standards for e-data exchange. The SCM system overcomes these problems by adopting platform-independent IT solutions, web-services, a network of trusted authority servers, and a novel “quasi-standard” solution for e-data exchange, with the use of home university campus cards to access facilities at host institutions.

The management of foreign student exchange is a complicated process. It involves students, faculty, administrative staff and external institutions. To the authors knowledge, there is no other comprehensive networked IT system available to facilitate administration of student mobility, make it better controlled, less laborious and faster, in a secure way. The IT solution contributes to overcoming the current barriers to academic mobility within Europe and elsewhere.

Designing of induction motors requires accurate calculation of the field distributions, especially in the case of PWM suppliers. The Finite Element Method (FEM) is useful tool for studying electromagnetic fields in motors, especially for the complicated geometries and nonlinear magnetic properties of such devices.

The purpose of this paper is to show the evolution of microsystems together with modeling methods in the space of dozen years as a result of finished research in the frame of several projects.

In this paper several approaches are presented. First, microsystems were built in multi project wafer technology. They were demonstrators like micromotor, micromirrors or micropumps modeled using dedicated design tool. A multi purpose chip was also designed using HDL description and FEM simulations. The next project concerned chemical sensors, where specialized models were developed and implemented in VHDL‐AMS in order to perform multidomain behavioral simulations. Dedicated tools were also developed for medical applications.

The evolution of MEMS technology is strictly connected with simulation and modeling methods. The success and short time to market need fast and accurate simulation methods. This paper shows that the approach depends on application. Moreover, it is connected with the access to the technology.

This paper presents a brief overview on projects performed in DMCS‐TUL department. It shows the evolution of modeling methods and technology used in developing and fabrication of microsystems for various applications.
