The goal of the diploma work is to describe the theoretical aspects of the consumer behaviour of the segment of seniors. In the practical part the marketing research in the field of tourism is described and realized. On base of outcomes of the research the evaluation and suggestion of marketing arrangements are decribed. There is also comparison of the situation in the field of tourism for seniors between Czech Republic and the Kingdom of Spain done. Final part of the thesis is focused on evaluation of the overall situation which was desribed: marketing research of the tourism and the demand of the seniors.

A key part of a fruit fly's development is the formation of segmentsin its body. These structures are built by the protein forms of so-called segment polarity (SP) genes. It is the asymmetric expression of SP genes which creates the fruit-fly's segmental structure. The SP genes and their products (e.g. proteins) can be said to form a system which is self-regulating, i.e. genes are used to make proteins and, in turn, proteins are used to turn genes on or off. How this system achieves stable asymmetry of this kind is mathematically interesting as it can be thought of in a different way - multiple symmetries in the same system. This is unusual and we attempt to explain how it is possible using a mathematical model constructed by von Dassow et al. When trying to understand a biological system of this kind, there are two main approaches - reductionist and holistic. We try to show that they are not mutually exclusive - we look at the whole system but reduce what is meant by the whole. For example, von Dassow's model is large scale and, using it as a template, we show that a similar (but smaller) model inherits its properties. Smaller models can be made by short-handing the translation process (through which RNA is used to make protein) wherever an SP gene has a unique protein form. Our data indicates that the simultaneous wild-type expression of key SP genes (engrailed and wingless) takes place only when cumulative regulation of the wingless gene by two SP proteins is weak. The absence of this regulation would explain coexistence of multiple mathematical symmetries in one system (representative of genetic asymmetry) as it acts like a division between them. In this way, the system itself can be thought to divide into two independent sub-systems which can be treated separately.

This paper will be concerned with some fundamental properties of a line. In particular, fundamental ordering properties of a line segment are covered.

Health and wellness are two buzzwords making their presence known in a variety of industries including hospitality, tourism, food and beverage and, leisure among others. As the obesity epidemic continues to be at the forefront of people's minds, health and wellness are topics that cannot be overlooked by the tourism and leisure industries. Due to the popularity of American's wanting to live more healthy and active lifestyles the average tourism consumer has changed considerably. The values of American tourists have altered from those of the past and now the tourism industry finds itself attempting to meet the needs and wants of this large and emerging health and wellness market. The purpose of this study is to determine whether there are different groups (market segments) of travelers based on their self proclaimed travel behavior. Using a factor-cluster market segmentation approach, this study attempted to delineate the segments of the U.S. traveling public. Based on four healthy living attitudes factors, cluster analysis was employed to identify similar respondents based on their attitudes towards healthy living. The findings show that there are two distinct groups: High Health Conscious and Low Health Conscious. Gender was shown to be statistically significant between the two groups. The study concludes with marketing implications of the study results, limitations, and suggestions for future research. / Master of Science

Reliability is a key aspect of power system design and planning. In this research we present a reliability analysis algorithm for large scale, radially operated (with respect to substation), reconfigurable, electrical distribution systems. The algorithm takes into account equipment power handling constraints and converges in a matter of seconds on systems containing thousands of components. Linked lists of segments are employed in obtaining the rapid convergence. A power flow calculation is used to check the power handling constraints. The application of distributed generators for electrical distribution systems is a new technology. The placement of distributed generation and its effects on reliability is investigated. Previous reliability calculations have been performed for static load models and inherently make the assumption that system reliability is independent of load. The study presented here evaluates improvement in reliability over a time varying load curve. Reliability indices for load points and the overall system have been developed. A new reliability index is proposed. The new index makes it easier to locate areas where reliability needs to be improved. The usefulness of this new index is demonstrated with numerical examples. / Master of Science

<p> Understanding human movement requires that biomechanists have knowledge of the kinematics and kinetics of the motion. Calculating the internal kinetics of a movement requires the input of segment inertial characteristics. Errors in the estimations of these body segment parameters (BSPs) may have detrimental effects on segmental kinetic calculations. </p> <p> The purposes of this study were to use i) investigate a new technique for measuring BSPs using dual photon absorptiometry (DPX) and ii) to investigate population differences in BSP values, develop geometric models to predict BSPs and compare geometric predictions with other prediction methods. </p> <p> In study 1, DPX measured whole body mass of humans with a group mean percent difference of -1.05% from criterion measurements. DPX also measured mass, centre of mass along a transverse axis (CM) and moment of inertia about the centre of mass (ICG) of a homogeneous object and a human cadaver leg with percent errors less than 4% from criterion measurements. </p> <p> In Study 2, 1 00 subjects were selected from four subpopulation groups according to gender (males/females) and age (19-30/ 55+ years). Using DPX, six body segments were measured for mass (forearm, hand, thigh, leg, foot, head) and four were measured for CM and radius of gyration (forearm, thigh, leg, head). Linear regression equations were developed and compared with geometric predictions and prediction equations from a popular literature source (Winter, 1990). </p> <p> Population differences were statistically significant for all body segments and all segment parameters except hand mass. Large segmental differences between individuals of similar size were also observed. The results showed the linear regression equations to provide the best estimations of BSPs. The geometric models and the predictions from Winter (1990) were poor for most segments. </p> <p> This study provided the foundation for a new method of BSP prediction. The population specific linear regression equations developed in this study should be used to predict BSPs for individuals similar to those examined in this experiment. While geometric models provided poor predictions, future improvements may increase their performance. </p> / Thesis / Candidate in Philosophy

<p> The present study develops a foot model to improve segment power estimates in the vertical jump. Modifications to the traditional foot model included the addition of a forefoot segment to allow for power flow across the metatarsal-phalangeal joint, and a re-definition of the ankle joint position to decrease foot segment length variability. The foot model was evaluated by comparison of the total segment power (TSP) with the rate of change of energy (RCE) of the foot segment. Pearson's correlation coefficients and percent root mean square (% RMS) error were used to compare curves. </p> <p> Power flow analysis was performed on a counter-movement jump (CMJ) and a squat jump (SQJ) for each of 8 male and 8 female subjects. Both a 4-Link and a 5-Link, sagittal plane, link-segment model were used to calculate the joint and muscle powers. </p> <p> The combination of both modifications to the traditional foot model (i.e. 5-Link(ankle) model), resulted in dramatic improvements for the match between the TSP and RCE. When comparing the traditional model with the 5-Link(ankle) model for the CMJ, correlation coefficients improved from -0.46 to 0.92 for the male group and from -0.50 to 0.77 for the female group. The %RMS error decreased from 380.5% to 35.4% for the male group and from 466.9% to 71.6% for the female group. SQJ improvements were similar. </p> <p> Ankle joint position re-definition succeeded in compensating for foot segment length changes in most cases, and indicates that a single point can be located to act as a hinge joint between the foot and leg segments throughout the vertical jump motion. Improvements associated with the addition of a forefoot segment to the traditional linksegment model indicate that substantial power flow occurs through the metatarsal-phalangeal joint during vertical jump motions. </p> / Thesis / Master of Science (MSc)
