    Notes: Hydrogen effusion spectra of oxidized Si samples are investigated and characteristic activation energies associated with the rupture of hydrogen bonds are estimated. Dislocation-enhanced solubility of hydrogen is found in deformed crystals and macroscopic diffusion depth (mm) can be realized. Hydrogenation is performed by exposure of the crystals to H2 gas at 800 °C. Beside the desorption of hydrogen bound close to the Si surface, the rupture of hydrogen-hydrogen bonds of molecules stored in deformed crystals is observed. The storage of the H2 molecules requires the presence of dislocations or deformation-induced point defects, and the H:H binding energy ranges from 2.7 to 3.8 eV. Most likely this energy variation comes from different local strain around dislocations. Atomic hydrogen is found to dominate the effusion kinetics.

    Notes: We report on optical absorption its magnetic circular dichroism (MCD), optically detected electron spin-resonance (ODESR), and electron nuclear double-resonance (ODENDOR) investigations of plastically deformed semi-insulating GaAs. By plastic deformation arsenic antisite defects are created which show a similar ODESR pattern as EL2 defects present in the material prior to deformation. EL2 and the new antisite defects can be distinguished by their different spectral dependence of the MCD. The new antisite defect formation starts at 2% deformation and is investigated as a function of the degree of deformation; additional EL2 defects are not created. With ODENDOR it is shown that the atomistic structure of the EL2 defects changes in the deformed GaAs.

    Notes: In as-grown GaP we investigated two phosphorous antisite related electron spin resonance spectra with respect to ligand hyperfine (lhf) interactions: basing upon a linewidth analysis, we attribute a hyperfine doublet with unresolved lhf structure (PA3) in n-GaP:S to a P-antisite defect with cubic symmetry. The lhf interaction of the well known lhf resolved PP4 doublet (PA1) in semi-insulating GaP:Cr was found to be temperature dependent. In plastically deformed GaP the two spectra showed contrary linewidth changes. In highly deformed n-GaP:S both signals were detectable. A new spectrum of low symmetry (GA1) was observed which we attribute to a gallium antisite related defect.

    Description / Table of Contents: Summary Deficits in current approaches of psychosomatic and psychiatric education for general practitioners are reviewed. A skill-based training was developed in line with the four step counceling approach of the „PLISSIT” approach: The GP helps in first step („permission”) the patient to accept his problem and assesses informations about causing and maintaining factors of his symptomatology. In the second step he should provide information about the disorder and reverse misunderstanding and passivity (Limited Information). The GP’s should develop preliminary strategies for change in the third step („coping strategies”, „symptom management”; „special suggestions”) and preparate the intensive phase of therapy as the last step. First results of the evaluation of the training program are presented demonstrate the effectiveness and acceptance of the education programm.
    Notes: Zusammenfassung Ausgehend von einer Analyse der Schwächen aktueller Ansätze der psychosomatischen Grundversorgung wird einerseits ein Ansatz vorgestellt, der störungsspezifisch im Rahmen eines Mehrebenenmodells pharmakologische und verbale Intervention aufeinander bezieht. Andererseits werden im Sinne eines zeitökonomisch abgestuften Vorgehens verschiedene Phasen durch das zugrundegelegte PLISSIT-Modell differenziert: In der Permission-Phase geht es um die Akzeptanzvermittlung und Problemanalyse hinsichtlich der vom Patienten geschilderten Beschwerden, in der Phase der „limited information” um die dialogische Erarbeitung eines Störungsmodells und den Aufbau einer aktiven Änderungsmotivation, in der Phase der „special suggestions” erfolgt eine konkrete Anleitung zur Selbstbeobachtung und -protokollierung des Problemverhaltens sowie die Vermittlung von Strategien zum Symptommanagement; in der letzten Phase der „intensive therapy” geht es um die Indikationsstellung und den Motivationsaufbau zur fachärztlichen bzw. fachpsychotherapeutischen Weiterbehandlung. Empirische Ergebnisse zur Evaluation des Weiterbildungskonzeptes an über 200 Teilnehmern werden referiert.
