Computer integration of cardboard production

A company for the development of software for industrial applications "PBS" Belgrade has designed a modern information system for monitoring and controlling production in the paper industry, which is completely integrated with the technological equipment and production processes. The paper presents the complete concept of the system, from electronic communication with business partners over computer support to all the production processes in the factory, to the delivery of the products to the customers. Realized as a CIM (Computer Integrated Manufacturing) system, it enables management to have a complete overview of the condition of all the production and business activities, and ensures momentary and complete reliable information about all the parameters of the business system. Although the system was developed for the needs of the cardboard factory "Umka", with particular modifications, it could also be used in other factories of the paper and cardboard packaging industry

Development and Evaluation of the Nurse Quality of Communication with Patient Questionnaire

Introduction Nurse/patient relationship as a complex interrelation or as an interaction of the factor patient and factor nurse has been a subject of a number of studies during the past ten years. Nurse/ patient communication is a special entity, usually observed within a framework of the wider nurse/ patient relationship. In that regard, we wanted to develop a standardized questionnaire that could reliably measure the quality of communication between nurse and patient, and be used by nurses

Proinflammatory cytokines (IL-1 beta and TNF-alpha) and chemokines (IL-8 and MIP-1 alpha as markers of pen-implant tissue condition

Analysis of pen-implant crevicular fluid (PICF) offers a non-invasive means of studying the host response in pen-implant disease and may provide an early indication of patients at risk for active disease. This study examined the PICF levels of interleukin-1 beta (IL-1 beta), tumour necrosis factor alpha (TNF-alpha), interleukin-8 (IL-8) and macrophage inflammatory protein-1 alpha (MIP-1 alpha) in patients with non-manifesting inflammation, early and late stages of mucositis. The study group comprised 90 adult healthy volunteers with endosseal titanium implants inserted. Samples were taken from pen-implant sulcus using a filter paper technique. Implant tissues were categorized clinically as healthy, early mucositis or advanced mucositis. Clinical manifestations were determined by: gingival index and bleeding on probing, plaque index and radiographic analyses. Cytokine concentrations were assesed using commercially available enzyme-linked immunosorbent assay kits. Patients from the control group (healthy patients) have significantly lower concentrations of IL-1 beta, TNF-alpha, IL-8 and MIP-1 alpha in PICF compared with both groups with mucositis. Positive correlation was noted in the control group between IL-1 beta and TNF-alpha and between MIP-1 alpha and IL-8 in the group with early mucositis. The results suggest that cytokines could be prognostic markers of implant failure
