The aging is not only a personal but also a social challenge from several aspects, several dimensions; a challenge aiming to build system approaches and solutions with a long term importance. Aims: the main aim of this research is to investigate the conditions and challenges in the modern living of the old people, primarily in terms of the social care. However, this research is concentrated on a big group of the population and their challenges are the most intensive in the modern living. The investigation of the conditions and challenges in the aging are basis and encouragement in realizing the progressive approaches in order to improve the modern living of the old people. The practical aim of the research is a deep investigation and finding important data, analyzing the basic indicators of the conditions, needs and challenges in order to facilitate the old population to get ready for the new life. Methods and techniques: Taking into consideration the complexity of the research problem, the basic methodological approach is performed dominantly by descriptive-analytical method. The basic instrument for getting data in the research is the questionnaire with leading interview for the old people. Results: The research showed that the old people over 70-79 years old in a bigger percentage manifested difficulties primarily related to the functional dependency, respectively 39,33 % of the participants in this category showed concern about some specific functional dependency from the offered categories. The percentage of the stomach diseases with 38,33 % is important, as well as the kidney diseases with 32,83% related to the total population and the category of the old people over 80. Conclusion: The old people very often accept the life as it is, often finding things fulfilled with tolerance and satisfaction. However the health problems of the old people are characterized with a dominant representation. The chronic diseases and the diseases characteristic for the aging are challenge in organizing adequate protection which addresses to taking appropriate regulations, programs and activities.

In this paper we investigate the inclusion of incomplete information in the relational database model. This is done by allowing nonatomic entries, i.e. sets, as elements in the database. A nonatomic entry is interpreted as a set of possible elements, one of which is the correct one. We deal primarily with numerical entries where an allowed set is an interval, and character string entries. We discuss the various operations of the relational algebra as well as the notion of functional dependency for the database model.

The objective of this paper was to study the evolution of cognitive status and of functional dependency in patients over 65 and how these relate to different demographic variables. The sample consisted of 259 elderly people admitted to the Hospital Neurotraumatológico in Jaen (Spain) with a diagnosis of bone fracture. Sociodemographic data was obtained through a semi-structured interview. Furthermore, the following tests were also administered: Barthel Index, Lawton and Brody’s Scale, Phototest, and Informant Questionnaire on Cognitive Decline in the Elderly. According to the results of this study, elderly patients show increased dependency during hospitalization and a mild recovery at discharge, but without regaining their dependency values prior to hospitalization. There is a differential incidence of functional decline as a function of gender, where women have significantly lower functional dependency at home than men and they do not decline as much as men do from their status prior to hospitalization. Also, we have encountered significant inverse relations between the different levels of dependency and cognitive status, and the age of the elderly patient. Moreover, married patients experienced greater functional gain than did the widowed patients, regardless of gender.
