    Description / Table of Contents: Summary The following contribution describes the planning of the production in a metallurgical plant with four blast furnaces. Basing on a fixed demand for pig iron per day which is to be fulfilled, it is to decide, how the production is to distribute among the four blast furnaces, when the costs of production are to be minimized. Subsequently the problem is extended by changing the demand for pig iron step by step. The optimal solution of this problem is achieved by using the methods of linear programming and mathematical statistics.
    Notes: Zusammenfassung Der folgende Beitrag beschreibt die Produktionsplanung für ein Hochofenwerk mit vier Hochöfen. Ausgehend von einer fest vorgegebenen Erzeugungsmenge muß entschieden werden, wie die Produktion auf vier Hochöfen zu verteilen ist, damit die Produktionskosten das Minimum erreichen. Für die Lösungsdarstellung wird die zu erzeugende Roheisenmenge schrittweise verändert. Die optimale Lösung wird mit Hilfe der Linearen Optimierung und der mathematischen Statistik ermittelt.

    Notes: Summary In a prospective study, prostate-specific acid phosphatase/prostate-specific antigen (PSAP/PSA) serum levels were simultaneously determined in 696 patients with benign prostatic hyperplasia (BPH), 202 patients with newly diagnosed, untreated prostate cancer (p-Ca), and 414 patients with previously treated p-Ca; in 165 of the 202 patients with newly diagnosed p-Ca, sampling was continued at 3-month intervals after the onset of various tumor-specific therapeutic modalities over a period of 3 years. The titers of the latter group were compared with the independently assessed individual clinical disease activity. A positive correlation could not be established between PSAP/PSA serum levels and either lesser differentiation or volume of tumor burden. PSA proved to be more than twofold more sensitive than PSAP in indicating malignancy and residual or recurrent neoplastic activity. No diagnosis of either p-Ca or progression of tumor at short-term follow-up was indicated exclusively by PSAP. However, at long-term follow-up of patients under treatment, exclusive indication of biologically active p-Ca by PAP in 0.7%–2.2% of cases requires simultaneous serial determination of both antigens for currently optimal monitoring. Considering the disadvantageous impacts inherent in its tissue specificity, PSA proved to be a most valuable tool, superior to PAP, as an immunochemical parameter in p-Ca.
