The article raises the issue of the determination of optimum values of technological parameters, necessary for the development of an effective control system of a technological process, on the basis of the experimental data collected when carrying out such a technological process for receiving a ready-made product of a required quality - 1.2 dichloroethane with the moisture content of no more than 0.001%. For the solution of the problem, the following tasks were set: to find the optimum values of the technological process parameters and to develop the operating program for the programmable logical controller which will provide for a necessary quality of a product of the technological process. As a criterion function for finding the optimum parameters of the moisture content of the dehydrated dichloroethane, the temperature and a pressure cubed column are selected as changeable parameters. Multicriteria optimization is performed with the use of a combination of neural network and the methods of minimization on the correct simplex and minimization of the Nelder-Mid on correct triangle and on basic vectors where neural network is applied to the description of a criterion function. As a result, after the calculation the values of technological parameters are received in three ways, and those values at which the quality of the received product corresponds to required quality are chosen. The correctness of the received values is checked with the use of the map of lines of the criterion function level. Also, with the use of the calculated parameters of a technological process, the operating program for the programmable logical controller, thanks to which the values of technological parameters are achieved and maintained so that the obtained ready-made product of the studied technological process - dehydrated dichloroethane - had the quality necessary for its further use in production, was developed.

For covering the real-time characteristics of an automation system during model-based design it is essential to model not only the function but also the behaviour of the control programs running on a real-time controller. This paper introduces an approach to the modelling and evaluation of the functional and time behaviour of programmable Logic controllers (PLC) on model level. The control algorithm consisting of UML statecharts is extended with an execution model of the controller which is also given as a statechart. The approach is integrated into a model-based design system for industrial control systems focusing on the field of production systems. An example will be employed to illustrate the benefits of a model-based design system which does incorporate real-time aspects of the controller.

Bovine tuberculosis (bTB) is an infectious disease of cattle that has an important impact in animal and public health. In spite of many efforts and resources invested in its eradication, bTB is still endemic in many countries. The intradermal tuberculin test- and- slaughter of bTB positive animals, with the slaughter surveillance, are the basis of bTB-control and eradication programs in place. However, the accuracy of intradermal testing tends to vary broadly with factors inherent to the country and to the individual immunity of the animal. In Uruguay, in spite of many efforts dedicated to bTB eradication, this disease has reached unprecedented prevalence levels in large, intensified dairy systems in the past years (2010–2018). This raised concerns regarding the suitability of the bTB-control strategies to reach eradication in this evolving demographic and management scenarios. In this dissertation we aimed to assess current and alternative control strategies for bTB in high-prevalence endemic settings, considering the identified demographic and management risk factors, to guide the design and implementation of optimal control and eradication procedures through mathematical modeling. Overall, we demonstrate that JD has an effect in bTB-diagnostic results at the herd and individual level in high prevalence bTB and JD coinfected populations studied, which needs to be addressed in the planning of bTB-control programs, specifically in regards of the performance of the bTB-diagnostic tools used. Still, in this co-infected scenario, the use of IGRA notably improved the sensitivity of detection in these herds, which can be beneficial in declining initial high bTB-prevalence levels. However, it is crucial to incorporate bTB-testing in young animals (< 12 months) to break disease transmission and achieve eradication. Further studies would be required in order to determine the best bTB-control strategy resulting from the interaction between bTB- and JD- epidemiology, test per

DIABETES SERVICE MANAGEMENT-TRAINING AND THE NEED FOR A PATIENT PERSPECTIVE - A L0-YEAR EVOLUTION OF TRAINING STRATEGIES AND GOALS

PATIENT EDUCATION AND COUNSELING 1995年第1-3期26卷 209-213页

In 1977, the Swedish National Board of Health and Welfare published guidelines for comprehensive care of patients with diabetes. The Stockholm County (1.6 million inhabitants) responded and opened a Diabetes Education and Training Centre, LUCD, in 1979. The goal was to reduce the impact of long-term complications. The centre should translate available knowledge about diabetes care into clinical practice, promoting a shift of patients and resources to the primary health care sector. Follow-up studies and new knowledge have changed the short-term training strategies;the long-term goal has remained unchanged. Current work is concentrated on training of staff, improving methods to support better patient learning, aiding organisational changes, and supporting large-scale interventions aimed at both patients, staff and the public. The patient can realize the goals. Knowledge and demands expressed by persons with diabetes are necessary for improvements of diabetes care. The skilled patient is also a guarantee for continuity of care. Regular follow-up of diabetes services was an important impetus for progressive change of short-term training strategies.

The activity of the Group for the control of Echinococcosis-Hydatidosis takes place in Elvas and Alandroal counties, north-east Alentejo, Portugal, an area where the prevalence of parasitism by Echinococcus granulosus is very high. This factor led to the first survey in 1991 and later, in 1998, to the establishment of a multidisciplinary group dedicated to the control of hydatidosis. The group carries out different activities: Surveys in humans (epidemiological questionnaire, blood collection and abdominal ultrasound survey);health education (talks for rural citizens, distribution of information in paper format, individual interviews with the target populations, collection of epidemiological data);close interaction/ collaboration with the Hospital de Santa Luzia de Elvas (serological analysis of collected sera;clinical evaluation of patients and surgery). Eighteen rural population areas were surveyed, representing 7.8% of the population. The activity of this multidisciplinary group aims at developing activity in the definitive host and livestock, having as a main goal the eradication of the parasite. © 2008 AEBM, AEFA y SEQC.

Objective. Describe the national rates of acquired invasive device-related infections in the ICU during 2003, 2004 and 2005, their etiology and evolution of the multiresistance markers. Design. Prospective, observational study. Scope. Intensive Care Unit or other units where critical patients are admitted. Patients. 21,608 patients admitted for more than 24 hours in the participating ICUs. Main variables of interest. Device related infections: pneumonias related with mechanical ventilation (N-MV), urinary infections related with urethral probe (UI-UP) and primary bacteriemias (PB) and/or those related with at risk vascular catheters (BCV). Results. In 2,279 (10.5%) patients, 3,151 infections were detected: 1,469 N-MV, 808 UI-UP and 874 PB/RVC. Incidence rates ranged from 15.5 to 17.5 N-MV per 1,000 days of mechanical ventilation, 5.0 to 6.7 UI-UP per 1,000 days of urethral probe and 4.0 to 4.7 PB/RVC per 1,000 days of vascular catheter. The predominant etiology in the N-MV was meticillin susceptible Staphylococcus aureus, Pseudomonas aeruginosa and Acinetobacter baumannii. The UI-UP were originated predominately by Escherichia coli, Candida albicans and Enterococcus faecalis. A. baumannii and E. coli have increased their resistance to imipenem and ciprofloxacin or cefotaxime, respectively, in the last year controlled. Conclusions. Elevated rates persist in all the infections controlled, without change in the etiology and increase of resistance of gram-negative bacilli.
