Coordination plays an important role in solving complex physical activities which arise during a biathlon race. We determined the level of coordination skills by measuring the time of a simple reaction to visual stimulus at rest by measuring the time response of complex reaction to visual stimuli by measuring the eff ect of visual-motor coordination (part of orientation skills – test Piorkowski) and by measuring the eff ect of visual-motor coordination (part of orientation skills – test Krzyzowy). In addition, we conducted a test of the simple and complex reaction aft er a short-term and long- term exercise. Among the tested sportswomen, the best results, both at rest and aft er exercise, have achieved twos Slovak athletes. Both results were above-average and slightly above-average. In order to develop physical coordination, we recommend biathletes to execute: the already known workout in diff erent environmental conditions, while practicing new coordination exercises especially systematics not focusing on their maximum improvement but to gain general skills for practice while implementing them in the fi rst part of the training.

Abstract KNN is a very popular algorithm for text classification. This paper presents the possibility of using KNN algorithm with TF-IDF method and framework for text classification. Framework enables classification according to various parameters, measurement and analysis of results. Evaluation of framework was focused on the speed and quality of classification. The results of testing showed the good and bad features of algorithm, providing guidance for the further development of similar frameworks.

Introduction: Alcoholism is the third most common psychiatric disorder among the elderly, yet it often goes undiagnosed in primary care setting. Objective: To estimate the prevalence of alcohol use disorders among elderly primary care patients in Bosnia and Herzegovina and to determine the presence of different health problems related to alcohol consumption. Method: The study was conducted in 10 family medicine practices. Family physicians randomly selected a group of 40 patients over 60 years of age registered with their practice. As a part of Comprehensive Geriatric Assessment, patients were asked to complete Alcohol Consumption Screening Questionnaire, Functional Status Questionnaire, Geriatric Depression Scale (GDS), Mini mental screening examination (MMSE), and Hamilton Anxiety Scale. Screening results were followed by additional clinical evaluation. To estimate the feasibility of Alcohol Consumption Screening Questionnaire, one family member or a caregiver of each patient was questioned about patient's habits and health problems. Results: Eighty-nine (22%) patients were current drinkers. Of those, 59% were harmful drinkers, 26% hazardous and 15% nonhazardous drinkers. Women accounted for 27% of current drinkers. MMSE revealed dementia symptoms in 37%, and symptoms of mild cognitive impairment (MCI) in 25% of current drinkers. Depression symptoms were found in 38% and anxiety symptoms in 6% of current drinkers. Functional status was decreased in hazardous and harmful drinkers. Conclusion: High percentage of older adults in Bosnia and Herzegovina is regular users of alcohol. Hazardous and harmful drinking is associated with significant morbidity. These findings demonstrate the usefulness and importance of the excess alcohol use screening in all primary care settings serving adults over age 60.
