The paper considers the possibilities and conditions for the unambiguous determination of the coordinates and angular orientation of the onboard direction – finder antenna placed on a moving object, based on the results of the azimuth-elevation radio direction finding of radio reference points. The coordinates of a moving object are determined by taken at one or several receiving points on board of a moving object measurements of radio signal delay time emitted simultaneously by at least three radio reference points. The unambiguous angular orientation in space is determined by measuring the viewing angles of at least three radio reference points of at least two direction finding pairs of receiving points with intersecting (non-collinear) bases. The article presents the mathematical features of determining the spatial position of onboard DF antenna, a general approach used for solving the problem of azimuth-elevation radio direction finding of three radio reference points, methods for determining the distance to radio reference points based on the results of their azimuth-elevation radio direction finding, and the analysis of the research results

The Relationship

Background/Aim. The vertical dimension of occlusion is a very important parameter for proper reconstruction of the relationship between the jaws. The literature describes many methods for its finding, from the simple, easily applicable clinically, to quite complicated, with the use of one or more devices for determination. The aim of this study was to examine the possibility of determining the vertical dimension of occlusion using the vocals ?O? and ?E? with the control of values o btained by applying cognitive functions. Methods. This investigation was performed with the two groups of patients. The first group consisted of 50 females and 50 males, aged 18 to 30 years. In this group the distance between the reference points (on top of the nose and chin) was measured in the position of the mandible in the vertical dimension of occlusion, the vertical dimension at rest and the pronunciation of the words ?OLO? and ?ELE?. Checking the correctness of the particular value for the word ?OLO? was also performed by the phonetic method with the application of cognitive exercises when the patients counted from 89 to 80. The obtained difference in the average values i n determining the vertical dimension of occlusion and the ?OLO? and ?ELE? in the first group was used as the reference for determining the vertical dimension of occlusion in the second group of patients. The second group comprised of 31 edentulous persons (14 females and 17 males), aged from 54 to 85 years who had been made a complete denture. Results. The average value obtained for the vertical dimension of rest for the entire sample was 2.16 mm, for the word ?OLO? for the entire sample was 5.51 mm and for the word ?ELE? for the entire sample was 7.47 mm. There was no statistically significant difference between the genders for the value of the vertical dimension at rest, ?ELE? and ?OLO?. There was a statistically significant difference between the values f or the vertical dimension at rest, ?OLO? and ?ELE? for both genders. There was a statistically significant correlation between the value for the vertical dimension at rest, ?OLO? and ?ELE?, for both groups of subjects. Conclusion. Determining the vertical dimension of occlusion requires 5.5 mm subtraction from the position of the mandible in pronunciation of the word ?OLO? or 7.5 mm in pronunciation of the word ?ELE?.

Unique Approach

PurposeConventional approaches to digital preservation posit that archives should define a Designated Community, or future user group, for whom they preserve digital information. Archivists can then use their knowledge of these users as a reference to help them deliver digital information that is intelligible and usable. However, this approach is challenging for archives with mandates to serve wide and diverse audiences; these archives risk undermining their efforts by focusing on the interests of a narrow user group.Design/methodology/approachA unique approach to this challenge was developed in the context of a project to build a digital preservation program at the Ontario Jewish Archives (OJA). It draws from previous research on this topic and is based on a combination of practical and theoretical considerations.FindingsThe approach described here replaces the reference of a Designated Community with three core components: a re-articulation of the Open Archival Information System (OAIS) mandatory responsibilities; the identification of three distinct tiers of access for digital records; and the implementation of an access portal that allows digital records to be accessed and rendered online. Together with supplemental shifts in reference points, they provide an alternative to the concept of a Designated Community in the determination of preservation requirements, the identification of significant properties, the creation of Representation Information and in the evaluation of success.Originality/valueThis article contributes a novel approach to the ongoing conversation about the Designated Community in digital preservation, its application and its limitations in an archival context.

Determination of responsibly professional position of modern medicine supposes investigation of the medicine activity basis and is connected with such domain reflections which appeal for the new ethical reference points of practical and theoretical medi- cine. At present modern medicine progress and the newly practice of professional medical care is at variance with settled moral principles and values and raises medical and philosophical problems which could not been considered objectively in Hippocrat's eth- ics or in the traditional medical norms of ethics and deontology. Necessity in the elaboration of bioethical imperative of responsibil- ity is keenly revealed in consiquense of the emerged breach between the level of biomedical theory and practice development on the one hand and the lag of medicine moral components of theoretical and practical medicine care on the other. In the article under consideration the condition of bioethical responsibility problem is analyzed in the professional legitimaton of medicine activity aspect. It also deals with formation conditions of bioethically responsible students in medical professional schools.
