Design Management in Poland
Zarządzanie designem w Polsce
Autorzy:
Świątek, Piotr
Opis:
Among many definitions of design it appears most frequently that it is a user-centered problem-solving process. Design management, in turn, is an activity, which ensures the smooth running of this process, taking into account all the necessary factors – economical, cultural, social or political. Possession of such knowledge and skills contributes to better fulfillment of the needs of customers, improves the competitiveness of the economy and the overall quality of life of the society. This dissertation aims to present what the design management is in theory and practice, to show the benefits that come from it and also to describe how does the education and practice of design management look like in Poland. This thesis is written on the basis of English literature, few examples of this topic in Polish literature, articles in design trade magazines and the author's experience gained from participation in numerous conferences on this subject and also from an e-learning training in design management, organized by the Institute of Industrial Design in Warsaw. It is hoped that this study will prove useful to those interested in design management issues and will contribute to the development of research in this field in Poland.
Wśród wielu definicji designu najczęściej pojawia się określenie, że jest to proces rozwiązywania problemów, w którego centrum znajdują się potrzeby użytkownika. Zarządzanie designem to z kolei działanie, mające zapewnić sprawny przebieg tego procesu z uwzględnieniem wszystkich koniecznych aspektów – ekonomicznych, kulturowych, społecznych czy politycznych. Posiadanie takiej wiedzy i umiejętności przyczynia się do lepszego zaspokajania potrzeb odbiorców, poprawienia konkurencyjności gospodarki oraz ogólnego komfortu życia społeczeństwa. Niniejsza praca stawia sobie za cel przedstawienie, czym jest design management w teorii i praktyce, jakie niesie za sobą korzyści oraz jak przedstawia się kwestia edukacji i praktyki zarządzania designem w Polsce. Pracę napisano na podstawie literatury anglojęzycznej, nielicznej w tym temacie literatury polskiej, artykułów w magazynach branżowych oraz doświadczeń autora wyniesionych z uczestnictwa w licznych konferencji poświęconych tej tematyce i odbytego e-learningowego szkolenia w zakresie design management organizowanego przez Instytut Wzornictwa Przemysłowego w Warszawie. Autor ma nadzieję, że niniejsze opracowanie okaże się przydatne osobom zainteresowanym tematyką zarządzania designem i przyczyni się do rozwoju badań w tej dziedzinie w Polsce.

Actin cytoskeleton in the extra-ovular embryo sac of Utricularia nelumbifolia (Lentibulariaceae)

Opis:
The actin cytoskeleton in the mature female gametophyte of angiosperms has been examined in only a few dicot and monocot species. The main purposes of this study were to identify how the actin cytoskeleton is arranged in the mature extra-ovular embryo sac in Utricularia nelumbifolia (Lentibulariaceae). We found that the extra-ovular part of the central cell has a well-developed actin cytoskeleton: actin microfilaments formed of long strands which run longitudinally or transversally to the long axis of the embryo sac. The exerted part of the central cell, which is exposed to the environment of the ovary chamber, is highly vacuolated and in the thin peripheral cytoplasm possesses a complicated network of actin microfilaments. The epidermal cells of the placenta that are in contact with the extra-ovular part of the embryo sac are crushed. The ultrastructure data of these cells are presented. We detected the accumulation of the actin cytoskeleton between the micropylar parts of the synergids and the extra-ovular part of central cell. This actin accumulation is unusual because in typical angiosperms the micropylar parts of the synergids form the apex of the female gametophyte.

A comparative morphology of the male genitalia of Aphididae (Insecta, Hemiptera) : part 2

Opis:
The present study provides new data related to the morphology of the male genitalia of Aphididae. The structure of the male genitalia of 39 species from 23 genera of Aphididae was studied using light and scanning electron microscopy. In the species studied, the genitalia of males consist of a phallus composed of the sclerotized basal part with its articulation and a membranous apical part-an aedeagus as well as parameres. This state probably represents the hypothetical plesiomorphic condition of the external male genitalia of aphids. According to the results of the present study, the male genitalia vary among subfamilies (the most varied in Lachninae). Both the phallus and parameres show great variability in their form and the number of setae and may provide characters of taxonomic and diagnostic importance. The shape, size, and modification of parameres are considered in conjunction with the phylogenetic relationships among the studied taxa. Compared with Lachninae, Greenideinae, Aiceoninae, the external genitalia of Aphidinae are less specialized, having many features in common with those of drepanosiphine aphids and differing little from the hypothetical condition. In dwarfish males of Anoeciinae, Thelaxinae, Hormaphidinae, and Eriosomatinae, the miniaturization of the body size affects on the modification of genitalia, mostly parameres. However, the homology of non-modified and modified structures of parameres is not clear.

Integument cell differentiation in dandelions (Taraxacum, Asteraceae, Lactuceae) with special attention paid to plasmodesmata
Autorzy:
Świątek, Piotr
Płachno, Bartosz
Kurczyńska, Ewa
Opis:
The aim of the paper is to determine what happens with plasmodesmata when mucilage is secreted into the periplasmic space in plant cells. Ultrastructural analysis of the periendothelial zone mucilage cells was performed on examples of the ovule tissues of several sexual and apomictic Taraxacum species. The cytoplasm of the periendothelial zone cells was dense, filled by numerous organelles and profiles of rough endoplasmic reticulum and active Golgi dictyosomes with vesicles that contained fibrillar material. At the beginning of the differentiation process of the periendothelial zone, the cells were connected by primary plasmodesmata. However, during the differentiation and the thickening of the cell walls (mucilage deposition), the plasmodesmata become elongated and associated with cytoplasmic bridges. The cytoplasmic bridges may connect the protoplast to the plasmodesmata through the mucilage layers in order to maintain cell-to-cell communication during the differentiation of the periendothelial zone cells.

Opis:
This scientific article presents an innovative concept of a hybrid power unit designed for ultralight aircraft, with the aim of improving energy efficiency and operational flexibility. As part of the development of the system, the construction of the combustion unit and the electric motor / generator, which are the key elements of this solution, was described. The advanced internal combustion engine controller and the bi-directional energy conversion converter have been developed and built to enable optimal cooperation of both energy sources. In order to carry out experimental research on the developed system, a special test stand was built on which a prototype drive unit was mounted. The results of the research include preliminary performance characteristics of the prototype drive unit and an analysis of the achievements that indicate the potential benefits of using such a hybrid drive unit. The article also summarizes the conclusions and recommendations for further work on improving this innovative solution.
