Paluch koślawy jest chorobą często występującą u kobiet. Wykonano RTG obu stóp w projekcji AP, bocznej i na palcach oraz MRI. Opracowano, trójwymiarowy model strukturalny szkieletu stopy. Przeanalizowano błędy wyznaczenia położeń poszczególnych znaczników. Zbadano równowagęu zdrowych osób metodą stabilograficzną. Pomiarów charakterystyk chodu dokonano na ścieżce podoskopowej. Względem młodszych kobiet przeprowadzono normowanie wyników starszych kobiet. Parametry charakteryzujące badane kobiety nie mają rozkładu normalnego. Profil chodu kobiet starszych opisano 19 parametrami. Różnice w chodzie obu badanych grup kobiet przejawiają się głównie w parametrach geometrycznych. Normy symetrii kobiet podano dla 1 kwartyla, mediany i 3 kwartyla.

Hallux valgus is one of the most frequent forefoot disease in women. There was taken RTG of both feet in the AP, lateral and tip toe projection as well as MRI. A three-dimensional structural foot skeleton model was developed. There was analysed the uncertainty of landmark positioning together with the influence on foot geometric features. Balance mechanism was examined in healthy subjects using the HUR stabilographic platform. Gait characteristics were made on the pressure distribution plate produced by ZEBRIS. There were separated two groups of younger women and a group of older women. Normalization of older women was carried out in relation to the younger group. The parameters characterizing the investigated women did not have a normal distribution. The gait profile of older women is based on 19 parameters. Differences in gait performance of both groups of women are mainly manifested in the geometric parameters. The norms of the symmetry index for the women are given as 1 quartile, median and 3 quartile.

Normal foot model is a geometric model of a healthy human foot. As the comparison of the processed feet requires a reference ideal healthy foot parameterization it was necessary to create such a model by defining skeleton geometric features and generating the feature set on a dataset population. Manual positioning of such number of landmarks is both a complex and time consuming task for a skilled radiologist, not to mention the total cost of such a procedure. Thus it was recommended to formulate an automated computer algorithm to perform this procedure with accuracy at a comparable level as the manual process. The following paper describes our approach based on automatic landmark positioning in a volumetric foot dataset. The proposed automated procedure is based on four main steps: manual landmark positioning on a reference dataset, registration of the reference dataset with the examined study, transformation of landmark positions from the reference dataset space into the examined dataset space, and calculation of the geometric features on the basis of landmarks positions. The results of our algorithm are presented and discussed in the context of pros and cons of the automated method itself as well as in the context of the generated normal foot model.

Wykonano badania zebranych próbek opadu zawieszonego (mgła) w celu oznaczenia w nich poziomu zawartości wybranych związków organicznych i nieorganicznych. Próbki pobierano w dwóch punktach na terenie Polski. Miejsca pobierania próbek podzielono ze względu na ich różny charakter: teren nizinny i szczyt górski. Stwierdzono obecność wybranych zanieczyszczeń na różnych poziomach stężeń w próbkach mgły oraz że poziom ten zależy od lokalizacji, ukształtowania terenu i warunków meteorologicznych, jakie panowały w okresie pobierania próbek.

Research on suspended precipitation (fog) samples was made in order to determine the concentration level of selected organic and inorganic compounds. The samples were collected at two sampling points in Poland. The sampling sites were divided according to the type of land topography: lowland area and mountain summit. On the basis of the conducted research it was concluded that the selected pollutants were determined on different concentration levels in fog samples and this level depends on location, land topography and meteorological conditions prevailing during the sampling period.

Qualitative and quantitative description of the heart wall motion is a very important field of investigation in modern cardiology. Abnormalities in heart motion are usually symptoms of life threatening cardiac dysfunctions therefore measurements of dynamic heart functions are of great clinical importance. The images of moving spatial heart structures can be efficiently acquired using 4D echocardiography. Unfortunately because of the low quality such images do not allow for precise measurements. To overcome this problem images need to be further processed and moving structures have to be extracted. In this work we present a method for estimating heart motion from 3D echocardiographic image sequence. On the basis of this method we have developed several visualization techniques that enable qualitative assessments of heart motions abnormalities. Together with quantitative measurements they may be become a useful tools in daily clinical practice.

Molecular mechanics calculation (using MM+, MMX and AMBER force fields) of all constitutional and topological isomers of C60H58R1R2 with R1,R2=H, Me revealed that "in,in" isomers are always the most stable, while the corresponding "out,out" isomers have the biggest energy. Moreover, a substitution of an "in" hydrogen atom by a methyl group in the confined volume of the C60 cage doesn't change, or even lowers, the steric energy. The dependence of steric energy on the distance between the "in" hydrogen atoms (or between the carbon atoms of "in" methyl groups) reveals highly irregular behaviour, for close neighbours, reflecting differences in the energies associated withconsiderable distortions of the fullerane skeleton.
