The research was carried out on a sample of 55 female high school students from Nis, 15 years of age (± 6 months). The aim of the research was to determine the canonical correlations between morphological dimensions, on the one hand, and tests for the evaluation of repetitive strength on the other, among the female students. The problem of this research was the evaluation of the influence of morphological dimensions on the achieved results for repetitive strength. 10 anthropometric measurements of morphological characteristics were used, which define longitudinal dimensionality and dimensionality of the skeleton, transversal dimensionality of the skeleton and circular dimensionality and body mass. Repetitive strength was evaluated by means of three tests. The results of the canonical correlation analysis have shown that a significant canonical factor can be found between the morphological dimensions (as the predictor system) and explosive strength (as the criterion system), along with a high corre analysis.

BACKGROUND: During colorectal surgical dissections, recognizing essential anatomy is crucial to prevent iatrogenic injury. This study builds forth upon previously identified new inherent anatomical spectral contrasts in fresh human colonic samples. AIM: Assessment of optical spectrometry for discriminating critical tissues (colon, adipose tissue, artery, vein and ureter) in colorectal surgery. PROJECT DESCRIPTION: Acquisition of in vivo AND ex vivo wide-band diffuse reflectance spectra (350-1830nm) during colorectal surgery, analysis of all separate tissue spectra using principal component analysis (PCA) and comparing tissue categories. PRELIMINARY RESULTS: In 6 consecutive patients 156 in vivo spectra (32 tissue spots) and 118 ex vivo spectra (24 tissue spots) were collected. PCA derived parameters were used to differentiate between tissue types. Distinctive spectral contrast features (partly within wavelengths invisible to the naked human eye) could indeed be identified for all tissue types. Visualizing these invisible contrasts may enhance surgical imaging (either during open or endoscopic surgery).

INTRODUCTION: In thyroid and parathyroid surgery iatrogenic injury of the parathyroid glands or the recurrent laryngeal nerve (RLN) is a possible complication that needs to be prevented. The visible contrast between thyroid and parathyroid tissue is delicate to observe. The aim of this pilot study was to collect in vivo spectral reflectance-signatures of critical tissue types encountered during thyroid and parathyroid surgery, and to assess the presence of useful spectral distinctive features that might be applied for future devices enabling intraoperative tissue-specific image contrast enhancement. METHODS: Wide-band spectra (350-1830nm, 1nm resolution) were collected in vivo during thyroid and parathyroid surgery. Subjected to tissue type accessibility, on average 2 tissue types per patient were measured. For each tissue type, 5 spectra were recorded per site, covering 1-2 sites per tissue type. Mean tissue spectra were calculated for all measured tissue types. After visually comparing these mean spectra, two spectral signature features for all individual measured sites were extracted: 1. Slope within the 650-700nm range; 2. Amplitude gradient between dominant local reflectance minimum and maximum within 1350-1830nm. RESULTS: In 10 consecutive patients 158 in vivo spectra were recorded on 32 tissue sites. Based on the mean diffuse reflectance spectra for thyroid, parathyroid and RLN, the estimated features for the three tissue types were plotted. Significance was tested using a paired Student's t-test and by applying a Holm-Bonferoni correction (criterion set to p<0.025). Regarding feature 1 significance was found for parathyroid (p=0.003) and RLN (p=0.006). With respect to feature 2 RLN was significant (p=0.001). Both investigated spectral features seem to offer added value to distinguish between the studied tissue types. CONCLUSION: To our knowledge, this study is the first to date to investigate in vivo spectral reflectance-signatures of critical tissues encountered during parathyroid and thyroid surgery, far beyond the spectral detection boundary of the human eye (i.e. the infrared light spectrum). Within the recorded spectral reflectance-signatures we identified two spectral features which may be used for further developments towards intraoperative image contrast enhancement and thereby facilitate differentiation of tissue structures, either during open or endoscopic surgery.

Besides significant benefits, the trend of e-commerce development gives rise to a lot of challenges in terms of developing trust between the company and the consumer. A lack of trust leads to withdrawal from e-transactions. The paper is thus aimed at identifying and explaining the most important factors that affect the increase in users' trust in e-transactions. Besides an analysis of available papers in this area, a field research was conducted on a sample of 512 respondents in Bosnia and Herzegovina in order to develop a structural model of users' trust in e-transactions. Research findings confirm that the basic factors of an online trust model are: website usability, privacy, security, expected product performance, loyalty, and electronic management of customer relations (e-CRM).

This paper presents an approach to the automated design of the initial conceptual database model. The UML activity diagram, as a frequently used business process modeling notation, is used as the starting point for the automated generation of the UML class diagram representing the conceptual database model. Formal rules for automated generation cover the automatic extraction of business objects and business process participants, as well as the automatic generation of corresponding classes and their associations. Based on these rules we have implemented an automatic generator and evaluated it on a real business model.
