RADIO EMISSION FROM AKARI GALAXIES
Pepiak, A.,Solarz, A.,Pollo, A.,Takeuchi, T.T.,Jurusik, W.,AKARI Team, AKARI Team The Korean Astronomical Society 2012 天文學論叢 Vol.27 No.4
It is a long known fact that there exists a tight correlation between far-infrared and radio emission both for galaxies hosting active galactic nuclei and for star forming galaxies. We probe the radio - infrared correlation for a sample of extragalactic sources constructed by the cross-correlation of the AKARI/IRC All-Sky Survey Point Source Catalogue, the AKARI/FIS All-Sky Survey Bright Source Catalogue, and the NRAO VLA Sky Survey. Additionally, all objects of our sample were identified as galaxies in NED and SIMBAD databases, and a part of them is known to host active galactic nuclei (AGNs). After remeasuring all the fluxes, in order to avoid small aperture effects, we compare the ratio of radio to infrared emission from different types of extragalactic sources, and discuss the FIR/radio correlation as seen by AKARI and make a comparison to the previous results obtained thanks to IRAS.

Journalistic Heritage of Karel Capek
Jiri Pesicka 아시아중동부유럽학회 2007 동유럽발칸학 Vol.9 No.1
This essay is dedicated to an important and constantly topical part of the Karel apek´s work, to his journalistic heritage. The text follows the periods of apek´s career as a journalist in a chronological order, but it also mentions his very beginnings as a newspaper contributor at the age of a junior high school student. His university years are taken into account as well, because that time had the decisive influence on the forming of the author´s view of the world. Karel apek wrote then some studies demonstrating his close relation to the philosophy of pragmatism, in which he saw an approach giving the people the possibility to shape and change the world on both knowledge and practical action level without the necessity of using violent revolutionary methods. The main part of the text makes the readers acquainted with the apek´s engagement in editorial staffs of two renowned Czech newspapers Nrodn listy and Lidov noviny. His contributions dedicated to a immense number of aspects of the surrounding reality are a true and detailed time mirror of the quieter and more dramatic periods of the Czechoslovak First republic. Karel apek, the close friend and the respectful expounder of the personality and the work of T.G. Masaryk, the first president of the Czechoslovakia, became himself the almost symbolistic representative of the democratic regime. He had to face the oppositional views from the side of both the extreme right and left wing orientated journalism. His brilliantly formulated contemplations on the role of nation, policy, culture and the tasks of the intellectuals in the time of endanger and peril from the side of Nazi Germany remain the most impressive part of apek´s journalistic heritage. 카렐 차페크(Karel Capek)의 저널리즘 유산

BACKGROUND The progenitors to lung airway epithelium that are capable of long-term propagation may represent an attractive source of cells for cell-based therapies, disease modeling, toxicity testing, and others. Principally, there are two main options for obtaining lung epithelial progenitors: (i) direct isolation of endogenous progenitors from human lungs and (ii) in vitro differentiation from some other cell type. The prime candidates for the second approach are pluripotent stem cells, which may provide autologous and/or allogeneic cell resource in clinically relevant quality and quantity. METHODS By exploiting the differentiation potential of human embryonic stem cells (hESC), here we derived expandable lung epithelium (ELEP) and established culture conditions for their long-term propagation (more than 6 months) in a monolayer culture without a need of 3D culture conditions and/or cell sorting steps, which minimizes potential variability of the outcome. RESULTS These hESC-derived ELEP express NK2 Homeobox 1 (NKX2.1), a marker of early lung epithelial lineage, display properties of cells in early stages of surfactant production and are able to differentiate to cells exhibitting molecular and morphological characteristics of both respiratory epithelium of airway and alveolar regions. CONCLUSION Expandable lung epithelium thus offer a stable, convenient, easily scalable and high-yielding cell source for applications in biomedicine.
