    Opis:
    Introduction. According to the World Health Organization, non-infectious chronic diseases will become the leading cause of disability by 2020 and can be the most expensive health problem. Type 2 diabetes, hypertension, smoking, poor eating habits, insufficient physical activity and the resulting overweight and obesity are among the main modifiable factors of non-infectious chronic diseases. The results of epidemiological studies indicate that the prevalence of these factors in the Polish population is constantly growing, which is associated with the dissemination of unfavorable eating habits and sedentary lifestyle. Their combating and preventive and educational activities of patients in the scope of modifiable lifestyle behaviors related to lifestyle should be implemented primarily through primary care physicians. Aim. To validate the Polish language version of Physician Survey of Practices on Diet, Physical Activity and Weight Control: Questionnaire on Adult Care. Material and methods. A Polish version of the questionnaire “Physician Survey of Practices on Diet, Physical Activity and Weight Control: Questionnaire on Adult Care” was created. Validation was carried out on a group of 30 primary care physicians. Results. Very good results in terms of internal coherence of the questionnaire were obtained - the Alpha-Crombach coefficient was 0.82. The level of reproducibility was established with an ICC factor, which was 0.81. Conclusions. The tested Polish version of the questionnaire can be used to conduct research among primary care physicians in Poland

    Opis:
    In 2008, the Japanese government enacted a new healthcare law that requires companies to reduce the weight of overweight employees suffering from so-called metabolic syndrome, and the weight of their spouses. In 2013, companies that fail to reduce the weight of their employees and their spouses will be penalized. So, companies aim to introduce tools to support to loose weight. At first, we developed the first version of mobile application, named HIPPO (Healthcare Information Platform Project), to support to loose weight in 2007. This application worked well during two months and 76% of users whose BMI was 25 or over lost their weight. However, this problem was that many users could not continue to use this application and users who could continued to use this application could loose weight. We thought that to develop application that made user continue to use was important. So, in 2008, redesigned the system architecture and application from three view points, (1) Address real user needs, (2) Rethink and streamline the data-entry model for food and exercise, (3) Make the user experience personal and engaging. We designed one simple application with limited functions and use email as a support tool. As the result, 84% of uses could continue to use the second generation application.

    Opis:
    Lekkie roboty (LWR) są nową generacją urządzeń przeznaczonych do zastosowań przemysłowych, które zaprojektowano tak mogły wykonywać czynności w otoczeniu człowieka. Z powodu zredukowanej masy ramion są podatne na deformacje oraz charakteryzują się złożonym modelem dynamiki, co w konsekwencji zmusza do stosowania złożonych układów sterowania. Praca prezentuje cząstkowe wyniki prowadzonych badań dotyczących sterowania LWR. Opisywane są trzy metody kontrolowania sztywności ramion traktowanych jako powłoki. Wyniki badań symulacyjne ramienia wykonującego trzy ruchy obrotowe są obiecujące w kontekście przyszłych zastosowań.
    Light-weight robots (LWR) are a new generation of industrial appliances that was designed to operate in an unknown environment with humans. Due to reduced mass such construction might to achieve a higher elasticity in the arms and a more complex dynamic behaviour, which requires advanced control techniques in order to obtain good performances and a high accuracy. This paper presents on-going research on active control of LWR arms elasticity. The three different approaches are described and tested for 3D single robot arm, which is interpreted as a cylindrical shell. Simulation results show that the proposed concepts are promising for future applications.

    Opis:
    The optimal control problems and a weight minimization problem are considered for elastic three-layered plate with inner obstacle and friction condition on a part of the boundary. The state problem is represented by a variational inequality and the design variables influence both the coefficients and the set of admissible state functions. We prove the existence of a solution to the above-mentioned problem on the basis of a general theorem on the control of variational inequalities. Next, the approximate optimization problem is proved on the basis of the general theorem for the continuous problem. When the mesh/size tends to zero, then any sequence of appropriate solutions converges uniformly to a solution of the continuous problem. Finally, the application to the optimal design of unilaterally supported of rotational symmetrical load elastic annular plate is presented.

    Opis:
    This paper presents an adaptive particle swarm optimization (APSO) based LQR controller for optimal tuning of state feedback controller gains for a class of under actuated system (Inverted pendulum). Normally, the weights of LQR controller are chosen based on trial and error approach to obtain the optimum controller gains, but it is often cumbersome and tedious to tune the controller gains via trial and error method. To address this problem, an intelligent approach employing adaptive PSO (APSO) for optimum tuning of LQR is proposed. In this approach, an adaptive inertia weight factor (AIWF), which adjusts the inertia weight according to the success rate of the particles, is employed to not only speed up the search process but also to increase the accuracy of the algorithm towards obtaining the optimum controller gain. The performance of the proposed approach is tested on a bench mark inverted pendulum system, and the experimental results of APSO are compared with that of the conventional PSO and GA. Experimental results prove that the proposed algorithm remarkably improves the convergence speed and precision of PSO in obtaining the robust trajectory tracking of inverted pendulum.
