ZusammenfassungDie Langerhans-Zell-Histiozytose (LCH) ist eine seltene histiozytäre Erkrankung (Inzidenz: 0,2–2,0/100 000 Kinder unter 15 Jahren) mit einem sehr heterogenen klinischen Verlauf. Spontane Regressionen werden ebenso beobachtet wie chronische Reaktivierungen. Das klinische Spektrum reicht von einem isolierten Befall des Skeletts oder der Haut, bis hin zur ausgedehnten Multiorganerkrankung mit einem progredienten und lebensbedrohli-chen Verlauf. Das diagnostische und therapeutische Vorgehen konnte durch prospektive internationale Studien der Histiocyte Society standardisiert werden. Dies resultiert in einer Verbesserung von Heilungsrate und Prognose. Je nach Krankheitsausdehnung reicht die Behandlungsstrategie von einer abwartenden Haltung oder dem Einsatz einer lokalen/topischen Therapie bei monosystemischer LCH (single system LCH; SS-LCH) bis hin zur systemischen Chemotherapie bei multi-systemischer LCH (MS-LCH). Auch auf dem Gebiet der Grundlagenforschung konnten in den letzten Jahren große Fortschritte im Hinblick auf ein besseres Verständnis der Biologie und Pathogenese der Erkrankung erzielt werden. Die dabei gewonnenen Informationen werden als Grundlage für neue Therapieansätze dienen.

Library And Information Education

The authors discuss the problems of library and information education. The lack of a single system of life-long education in the library industry is stressed. The Model Standard of Public Libraries as a reference point for education reinvention is analyzed. The main vectors of public libraries activities defined in the Model Standard are considered, along with the desirable professional competences. The ratio of the libraries’ main tasks and functionalities and the professional education is examined.

Definition Of

: Hemorrhoidal Disease (HD) is widely diffused throughout the general population. The system of classification currently used to categorize this pathology is that of Goligher (1975). This system only defines the morphology of the most represented hemorrhoid bearing. Several attempts in literature have been made to replace this system, but as of yet, no single system has been universally accepted. Some studies, however, have succeeded in identifying specific characteristics, besides morphology, that would be able to aptly define HD. An analysis of this literature, with careful consideration of the scores that have previously been proposed, is necessary in order to deepen and stimulate discussion about a possible new definition of HD.

Kalman Filter Method

In order to evaluate the performance of GPS / BDS, RTKLIB, an open-source software of GNSS, is used in this paper. In this paper, the least square method, the weighted least square method and the extended Kalman filter method are respectively applied to BDS / GPS single system for data solution. Then, the BDS system and GPS system are used for fusion positioning and the positioning results of the two systems are compared with that of the single system. Through the comparison of experiments, on the premise of using the extended Kalman filter method for positioning, when the GPS signal is not good, BDS data is introduced for dual-mode positioning, the positioning error in e direction is reduced by 36.97%, the positioning error in U direction is reduced by 22.95%, and the spatial positioning error is reduced by 16.01%, which further reflects the advantages of dual-mode positioning in improving a system robustness and reducing the error.
