    Description / Table of Contents: Zusammenfassung Eine Vollerhebung der sozialpsychologischen Situation von Fluglotsen (N = 517) mit nominalstatistischen Daten wurde clusteranalytisch ausgewertet. Das Ergebnis der multivariaten Analyse wurde unter methodischen und inhaltlichen Aspekten mit univariaten Auswertungen von Singer und Rutenfranz (1972) verglichen: Cluster zur personalen Umgebung spezifizieren Aussagen zum typischen Lotsen. Mittlere Bedeutungsrangfolgen zu Variablen der Arbeitssituation werden in Gruppen gegenteiliger Meinung aufgelöst und in Beziehung zur Arbeitszufriedenheit gebracht. Gruppen von Lotsen mit guter Zufriedenheit werden von stark unzufriedenen separiert. Aussagen zur negativen Einschätzung des gesamten Berufsweges werden durch Cluster belegt, besondere Probleme einzelner Dienstorte herausgefiltert. Die Gesamtheit der Lotsen wurde nach subjektivem Gesundheitsstatus mit Krankheitssymptomen und therapeutischen Maßnahmen gegliedert. Beziehungen zwischen Gesund-heitsstörungen, Arbeitsunzufriedenheit, Belastung und Bedeutungsgewichtung von Aspekten der Arbeitssituation werden aufgezeigt und teilweise durch Motivations-und Zufriedenheitstheorien erklärt.
    Notes: Summary A total inventory about the sociopsychological situation of german air-traffic controllers (N = 517) with data on nominal scales was analysed by cluster analysis. The results of the multivariate analysis were compared with those of univariate analysis by Singer and Rutenfranz (1972) in methodology and substance: Clusters concerning the family situation specify statements to the “typical controller”. Mean rankings of importance of variables of the work-situation are split into groups of contradictory meanings and are related to job satisfaction. Groups of controllers with good job satisfaction are separated from the dissatisfied. Negative estimations of the career are substantiated by clusters. Special problems of some airports are filtered out. The collectif of all air traffic controllers is structured according to subjective health status, symptoms of illness and therapeutics. Relations between health disturbances and job satisfaction, stress and rankings of importance of aspects of work situation are pointed out and partially explained with motivation- and job-satisfaction theories.

    Notes: Summary A case of a 5 1/2 years old boy with a plexiform ameloblastoma of the jaw is reported. 6 years after resection of the primary tumor metastases developed in a lymph node at the left side of the neck and in both lungs. Thoracotomy revealed many small metastases spread all over the lungs. Light and electron microscopical studies of the primary tumor showed a typical plexiform ameloblastoma without signs of malignancy. In the metastases, however, these studies revealed the histological criteria of a malignant tumor with marked pleomorphism of tumor cells, increase of heterochromatin, enlargement of nucleoli and invagination of nuclear membranes. After enucleation of two metastases and therapy with cytostatic agents for several months no further metastases have been observed within a period of 6 years. Comparative light and electron microscopic studies of both primary tumor and metastases demonstrate that there are no histological criteria to identify the primary tumor as a malignant ameloblastoma. Ameloblastoma with distant metastases is a rare tumor in children, this case is only the third reported in the literature.

    Notes: Abstract On the basis of studies of about 100 collections of the groupConocybe mesospora and after comparison of extra-European material we conclude that, within the European representatives of this complex, it is necessary to distinguish nine species and two varieties. Three new species are described:Conocybe subxerophytica Sing. & Hauskn.,C. minima Sing. & Hauskn. andC. roberti Sing. & Hauskn. C. mesospora var.subalpina Sing. is now recognized as an autonomous species, butC. brunneola (Kühn. ex)Kühn. & Watling is understood as variety ofC. microspora (Velen.)Dennis. C. excedens var.pseudomesospora Sing. & Hauskn. is described as a new variety.C. affinis Sing. is indicated for Europe.C. microsperma Sing. is the new name ofC. microspora (Vel.)Dennis ss.Dennis. A full description of nine taxa of this group is given and a key to 11 taxa occurring in Europe added. Seven taxa are illustrated for the first time with colored photographs. All taxa known to us from other continents and belonging to theC. mesospora group have been compared with the most similar European species or varieties.
