Resumen. Este articulo presenta el diseño e implementación de un Sistema Tutor Inteligente (STI) capaz de ser configurado por diferentes expertos en áreas consideradas importantes para un STI. Se incorporan las características necesarias para que sean los expertos los que provean las herramientas necesarias para dotar al STI con la capacidad que requiere, para lograr un mayor impacto en el apre...

BACKGROUND The role of the GP in the care of sexually transmitted infections (STIs) is unclear. AIM We studied the prevalence of STI related consultations in Dutch general practice in order to obtain insight into the contribution of the GP in STI control. DESIGN OF STUDY A descriptive study. SETTING The study took place within the framework of the second Dutch National Survey of General P...

OBJECTIVES A survey was conducted to assess the adequacy of sexually transmitted infections (STI) prevention and control policies and programmes in the European region (including the central Asian republics). METHODS An adapted World Health Organization (WHO) model questionnaire was sent to ministry of health officials in all 45 countries of Europe and central Asia. The questionnaire included...

The study was to measure the prevalence of sexually transmitted infection (STI) symptoms among women in Accra, Ghana, to identify characteristics that predispose to STI symptoms and to identify factors that influence health-seeking behaviour of women with STI symptoms. Data were collected by trained interviewers through questionnaire interviews of 3183 women. Data analysis was restricted to 132...

INTRODUCTION Control of sexually transmitted infection (STI) remains challenging in most regions; Latin America (LA) is no exception. The Latin American and Caribbean Association for the Control of Sexually Transmitted Infections (ALAC-ITS) implemented a survey to collect information on STI programmes in the region. This paper highlights some important sexual behavioural trends from recently pu...

A new, systematic approach to the synthesis of sti®ness by springs is presented using screw (spatial vector) algebra. The space of solutions is fully characterized for all sti®nesses realizable by springs. The main result shows that a rank r sti®ness can always be synthesized by r springs. Further, a sti®ness can be synthesized by an arbitrarily large number of springs greater than r: Algorithm...

The Abl tyrosine kinase inhibitor STI-571 is effective therapy for stable phase chronic myeloid leukemia (CML) patients, but the majority of CML blast-crisis patients that respond to STI-571 relapse because of reactivation of Bcr-Abl signaling. Mutations of Thr-315 in the Abl kinase domain to Ile (T315I) were previously described in STI-571-resistant patients and likely cause resistance from st...

INTRODUCTION The emergence of drug resistance among bacterial, viral and protozoan sexually transmitted infections (STI) in recent years threatens to undermine global STI control programmes. While this review will focus on microbiological resistance determinants for two important bacterial STI pathogens, namely Neisseria gonorrhoeae and Treponema pallidum, it is important to appreciate that a n...
