Plantations of Serbian spruce (Picea omorika [Panč.] Purkyně) reach an age over 70 years at the Masaryk Forest Training Forest Enterprise (TFE) at Křtiny. They occur at different sites of the TFE, which is situated north of Brno between Blansko, Jedovnice and Brno in the Czech Republic. The paper presents an assessment of primary mensurational values (diameter at breast height d.b.h., height h, Derbholz volume m<sup>3</sup>), fertility, mortality and general health condition. The present registered number of Serbian spruce trees is 425 (from originally 750 individuals) in 25 localities and 12 GFT (groups of forest types). A comparison of Serbian spruce mensurational data with growth tables indicated that Serbian spruce on GFT 4K makes up for the tabular mean values of Norway spruce (Picea abies [L.] Karst.) in yield class +1.

Differentiation of forest technologies according to ecosystem properties is a necessary step to achieve sustainable forestry. A forest typological system is considered to be the basic unit of ecosystem differentiation in the Czech Republic. Terrain characteristics, potential water erosion and applicable harvest technology were examined for 44 forest sites in a landscape segment of the Jizerské hory Mts. Forest site was found homogeneous in terms of terrain and technological properties. Edaphic category and groups of forest types as higher classification units and management sets as units of alternative classification showed lower homogeneity insufficient for operational planning.

Abstract Background Night work has negative effects on sleep, sleepiness and fatigue with repercussions in performance, safety and health. Therefore, implementing sleep hygiene educational intervention seems of tremendous importance to industries. The questions underlying this study were: 1) To what extent do shift workers experience risk levels of fatigue and sleepiness?; 2) May a sleep hygiene program be associated with improvements on fatigue and sleepiness? Methods The study was conducted in industry and employed a pre pos-test design using the Epworth's Sleepiness Scale and Chalder's Fatigue Scale. From 471 night workers assessed 45 participants at risk for fatigue and sleepiness (93.3% males), mean age of 31 years (SD = 7.3), were selected for the intervention, composed of four sessions along five months, delivered by the occupational medical doctor. The first three sessions, in small groups, focused in sleep literacy and sleep hygiene; the last one, individual, focused in clinical issues (personalized intervention plan). Results Results suggested that 9.6% (N = 45) of the night workers were at high risk (higher levels of fatigue and sleepiness). After intervention, paired T tests revealed significant decreases (p&lt;.001) on mean values for fatigue from T0 (M = 6.67; SD = 2.23) to T1 (M = 4.78; SD = 3.02), and for sleepiness from T0 (M = 15.49; SD = 4.39) to T1 (M = 11.8; SD = 5.95). Along the intervention, participants pointed out family-related routines as an obstacle to daytime sleeping period. Conclusions Results support the importance of this educational program focused on sleep hygiene, in reducing sleepiness and fatigue. The program is now part of the occupational health procedures of the company but qualitative results also suggest the importance of including the family in the program, as an innovative procedure. In summary, education of night workers and their families is needed regarding sleep habits in order to promote safety and health in workplace. Key messages The sleep hygiene program implemented in permanent night workers allowed to reduce fatigue and sleepiness. Fatigue and sleepiness management improvements might contribute to reduce the risk of accidents in the workplace and increase the workers’ health condition.

Lobular Panniculitis

Lobular panniculitis is a skin condition that may be the first sign of underlying pancreatic disease. Though rare, the condition has been sufficiently well defined and pathognomonic, thus making differentiation from idiopathic lobular panniculitis quite possible. A 77-year-old woman was in apparently good general health condition when developed skin lesions in a form of erythematous painful fluctuant nodules localized predominantly on the breast, but also present on the arms, thighs, and trunk. Her serum and urinary amylase levels were respectively 3 and 8 fold higher than normal. On histology, skin biopsy showed acute lobular panniculitis with large foci of adipocyte necrosis. Examination of the breast excluded any specific process other than nodular subcutaneous inflammation, but revealed a tumor of the pancreatic head. The nodules spontaneously ulcerated exuding an oily thick brownish material. Her condition deteriorated, and she became progressively debilitated. The patient died before operation, within the next 3 weeks. Subcutaneous fat necrosis was the first manifestation of an otherwise occult pancreatic disease with fatal outcome.

The study was carried out in Serbian spruce (Picea omorika Panc/Purkyn?) plantations in the western Serbia. The paper presents results of the analysis of crown development. The following elements were analyzed: total tree height, height of the crown base, absolute and relative crown length, maximal crown diameter, coefficient of crown spreading and degree of crown girth. We discuss approaches to the modeling of tree crown growth and development, growing under favorable environmental and stand conditions, without anomalies in development. In order to establish the relationship between analyzed factors, regression analyses were applied. Data fitting was by the analytic method, by the implementation of Prodan?s functions of growth, linear and parabolic function. Received models can be used for the simulation of various growth and developing processes in forest.

Alder decline along watercourses is one of the marked manifestations of tree decline in the Czech Republic. Local decline of alder trees is documented in the Czech Republic for about 15 years. The aim of this paper is to evaluate causes of alder decline and assess health conditions of other species of riparian stands at 2 localities on the medium reach of the Lužnice River. Effects were studied of abiotic and biotic stressors on the health condition of tree species. No fungal pathogen was found in tissues of declining alders which would be present in all trees and which could be considered to be the main causal agent of the decline. Even an occurrence of the causal agent of alder decline named alder-Phytophthora has not been proved. Tree-ring analyses demonstrated decreasing trends of an increment in alders; however, an abiotic or biotic factor showing direct effects on the fluctuation of tree ring dimensions has not been positively determined. A marked role in the alder decline is demonstrated particularly by abiotic factors accompanied by the secondary activation of some pathogens. Generally, the phenomenon can be named as polyetiologic decline.
