[Status of radiation protection courses for physicians--plea for a change in paradigm]. / Zur Situation der Strahlenschutzkurse für Arzte--Plädoyer für einen Paradigmenwechsel.

The purpose of this study was to evaluate the acceptance of the statutory course of radiation protection, which is attended by physicians. As a first step towards problem based quality management, an anonymous questionnaire was used to assess the participants' opinions. The present methods in teaching, practice-orientation of the educational objectives, the prize and efficiency of the course were judged poor. Neither valid indicators of quality nor a quality management of the course exists. Facing the status quo and future demands within the medical community and society there is a serious need for reshaping radiology. It is emphasized that instead of marginal corrections only a strategic and fundamental approach to a paradigmatic reorganization will meet success.

[Analysis of action potentials of muscles by a small general purpose computer (author's transl)]. / Analyse von Muskelaktionspotentialen mit Hilfe eines Prozess-Rechners

To measure the duration of action potentials by a computer, the following steps are necessary: 1. automatic selection of suitable potentials from the EMG 2. identification of equal potentials (action potentials of the single motor unit) 3. measuring the durations of potentials, defined by the distance between first and last deviation from the base line. We noticed that the automatic evaluation of durations of single potentials is greatly deteriorated by base-line fluctuations. Therefore we average about 16 action potentials, stored in the computer, of the same single motor unit and measure the duration of the averaged potential.

[Technical organisational problems and development tendencies in medical data processing (author's transl)]. / Technisch-organisatorische Probleme und Entwicklungstendenzen in der medizinischen Datenverarbeitung

All uses of "Medical Data Processing", which make greatly divergent demands on the computer because of the different applications by different user groups, are to be considered from the points of view of hardware, software and organisation. Further possibilities for the complex information systems in the hospital arise from the more recent development of computer technology, also with regard to the reliability of the hardware. Hand in hand with this, an improvement in the system software can be seen for the real-time processing and time sharing. But organisation od design, planning, installation and operation is of particular importance for medical information systems. This also includes the preparatory training of the hospital personnel and the observance of data protection.

[Criteria for the system selection in medicine (author's transl)]. / Kriterien für die Systemauswahl in der Medizin

The selection of an electronic data processing system for use in the medical field is in many cases complicated by the fact that the tasks have not yet been defined accurately in detail. Therefore, the technical system planning may only be carried out on the basis of an organization study which, among other things, is to provide bases for answering questions about the structure of this system, about the places where subsystems should operate in the hospital, and about the individual levels of implementation. When selecting the system, the criteria to be taken into consideration include the technical efficiency, organizational range of application, reliability, assistance by the manufacturer and, last but not least, the cost - bearing in mind that, in the medical field, the weights may be placed quite differently from the commercial field. With this planning consideration should also be given to the possibilities of utilization not basing on a system of one's own.
