Full textAbstract:
The aim of this thesis was to investigate obesity and weight change in two English prisons using both qualitative and quantitative methods. The research incorporated the first study to assess UK male prisoners’ weight change during imprisonment, as well as the first study to take into consideration factors associated with weight change specific to the prison setting. Data collection, for both qualitative and quantitative components of the study, started in May 2013 and ceased in November 2015. Qualitative interviews were undertaken with prison nurses (17 interviewees) and prisoners (19 interviewees) to obtain an understanding of how imprisonment and the prison setting can influence a prisoner’s weight. These interviews showed similar findings with both groups identifying food and physical activity as important factors that might influence a prisoner’s weight. These opinions were similar to views that might be expressed in a community setting. However, in addition, both groups identified how imprisonment and the prison environment created a unique setting for weight management. These contextual factors influenced health related behaviours and provided a greater understanding of the determinants of prisoners’ health. Power was a key theme, shown to exist in many different forms and having a positive and negative influence on prisoners’ health related behaviours. These were shown to be influenced by three main sources of power: the prison, other prisoners and impact of the outside world. Time, in various forms, was also found to play an important role in dictating prisoners’ health-related behaviours. The quantitative study demonstrated the complex relationship between imprisonment and weight and the influence of age on weight change. Findings from the quantitative study supported the results from the two qualitative studies showing how prison culture impacted on weight and weight change. The final discussion utilises various models of embodiment, including those specific to men’s health, to understand the results of this research project. The final conclusion challenges some commonly held perceptions of prisoners’ health related behaviour and provides a theoretical model that could be developed to provide more appropriate care for prisoners in the future.

This thesis studies several problems dealing with weighted inequalities and vector-valued operators. A weight is a nonnegative locally integrable function, and weighted inequalities refers to studying a given operator's continuity from one weighted Lebesgue space to another. The case where the underlying measure of both Lebesgue spaces is given by the same weight is known as a one weight inequality and the case where the weights are different is called a two weight inequality. These types of inequalities appear naturally in harmonic analysis from attempts to extend classical results to function spaces where the underlying measure is not necessarily Lebesgue measure. For most operators from harmonic analysis, Muckenhoupt weights represent the class of weights for which a one weight inequality holds. Chapters II and III study questions involving these weights. In particular, Chapter II focuses on determining the sharp dependence of a vector-valued singular integral operator's norm on a Muckenhoupt weight's characteristic; we determine that the vector-valued operator recovers the scalar dependence. Chapter III presents material from a joint work with M. Lacey. Specifically, in this chapter we estimate the weak-type norms of a simple class of vector-valued operators, but are unable to obtain a sharp result. The final two chapters consider two weight inequalities. Chapter IV characterizes the two weight inequality for a subset of the vector-valued operators considered in Chapter III. The final chapter presents examples to argue there is no relationship between the Hilbert transform and the Hardy-Littlewood maximal operator in the two weight setting; the material is taken from a joint work with M. Reguera.

Full textAbstract:
The Hilbert transform has become increasingly popular over the years due to its wide ranging applications not only in mathematics, but also in many other applied areas. In a quest for more applications, studying various aspects of its two weight forms has been a subject of high interest as early as the 1970’s. Of special interest is the interface of the Hilbert transform with the notions of Carleson measures and the system of reproducing kernels in spaces of analytic functions. Though these notions have proved to be of fundamental importance and ubiquitous in the development of function theoretic spaces, their properties for many significant spaces, including the model subspace of the Hardy spaces H2 ;have not yet been well understood. The present thesis focuses on this interface and provides answers to several problems encompassing them. The thesis consists of five chapters. The first chapter provides an up-to-date review of the relevant background literature. The remaining chapters contain results that have been published by, or intended for, international journals. The work in chapter two covers the problems of unitarity, invertibility, boundedness, and surjective mapping properties of the two weight discrete Hilbert transforms, and a complete solution is obtained for the first one. Our solutions for the remaining problems are complete under a sparsity priori growth condition. Under such a condition, we describe bounded two weight Hilbert transforms in terms of a relatively simple A2 conditions. As a consequence, computable geometric criteria have been established for invertibility of such maps. Chapter two also provides all the basic underpinnings for the materials presented in Chapter three and Chapter four, where links have been established to interpolate all our results on the weighted transforms into statements about Carleson measures and systems of reproducing kernels in certain Hilbert spaces, of which de Branges spaces and model subspaces of H2; are prime examples. As an application, a connection to the Feichtinger conjecture, which is known to be equivalent to dozens of other conjectures including the famous Kadison–Singer problem, is pointed out and verified for certain classes of spaces. Chapter five deals again with normalized reproducing kernel Riesz bases in model subspaces of H2 generated by the class of meromorphic inner functions. In this chapter, the approach to studying such bases digresses somewhat from the methods used in the preceding chapters. Here, we study the normalized kernel bases from an equality of spaces perspective. It is known that such bases can be described in terms of equality of spaces whenever the kernels are associated with points all from the real line. When the points are from the upper half-plane, it is now proved that the analogous conditions may still be sufficient while failing to be necessary.

Kerr, Robert. "Toeplitz products and two-weight inequalities on spaces of vector-valued functions." Thesis, University of Glasgow, 2011. http://theses.gla.ac.uk/2469/.
Full textAbstract:
This thesis is concerned with operators on certain vector-valued function spaces. Namely, Bergman spaces of \mathbb{C}^n$-valued functions and L^2(\mathbb{R},\mathbb{C}^n,V)$, where $V$ is a matrix weight. We will study products of Toeplitz operators on the vector Bergman space $L^2_a(\mathbb{C}^n)$. We also study various operators, including the dyadic shift and the Hilbert transform, between $L^2(\mathbb{R},\mathbb{C}^n,V)$ and $L^2(\mathbb{R},\mathbb{C}^n,U)$. These function spaces are generalizations of normed vector spaces of functions which take values in $\mathbb{C}$. The thesis is split into two distinct areas of function space theory: analytic function spaces and harmonic analysis. There is, however, a common theme of matrix weights, particularly the reverse Hölder condition on matrix weights and a generalization of the $A_p$ conditions on matrix weights for $p=2$ and $p=\infty$.

Full textAbstract:
Backpack weight distribution may affect economy by conserving energy and thus potentially prolonging fatigue. Research has not however examined effects of backpack weight distribution on subjective measures of intensity and comfort. Heart rate (HR) and overall and differentiated Ratings of Perceived Exertion (RPE) were examined during simulated backpacking with differentially weighted backpacks. Volunteers (n=27) completed two simulated hiking trials on a treadmill. Trials consisted of 15 minutes walking at 0% grade followed by 15 minutes walking at 10% grade at 2.5 mph (males) or 2.0 mph (females). Subjects wore an internal frame backpack packed to contain 25% of their individual body weight). In a counterbalanced order, packs were placed with either a high weight distribution (HWD) (3:1:1 ratio) placing more weight near the shoulders, and a low weight distribution (LWD) (1:1:3 ratio) placing more weight near the hips. Heart rate (HR), RPE-Overall, RPE-Legs, RPEShoulders, and RPE-Back were recorded every three minutes and compared between trials using repeated measures ANOVA. HR between HWD and LWD was similar at 0% as well as 10%. Overall and differentiated RPE's were not significantly different between (HWD vs. LWD) at 0% or 10%. Results suggest backpack weight distribution (HWD vs. LWD) does not significantly influence HR and perceptual measures during simulated hiking at a 0% or 10% grade.

Full textAbstract:
In this thesis we study the application of trace maps over Galois fields and Galois rings in the construction of non-binary linear and non-linear codes and mutually unbiased bases. Properties of the trace map over the Galois fields and Galois rings has been used very successfully in the construction of cocyclic Hadamard, complex Hadamard and Butson Hadamard matrices and consequently to construct linear codes over integers modulo prime and prime powers. These results provide motivation to extend this work to construct codes over integers modulo . The prime factorization of integers paved the way to focus our attention on the direct product of Galois rings and Galois fields of the same degree. We define a new map over the direct product of Galois rings and Galois fields by using the usual trace maps. We study the fundamental properties of the this map and notice that these are very similar to that of the trace map over Galois rings and Galois fields. As such this map called the trace-like map and is used to construct cocyclic Butson Hadamard matrices and consequently to construct linear codes over integers modulo . We notice that the codes construct in this way over the integers modulo 6 is simplex code of type . A further generalization of the trace-like map called the weighted-trace map is defined over the direct product of Galois rings and Galois fields of different degrees. We use the weighted-trace map to construct some non-linear codes and mutually unbiased bases of odd integer dimensions. Further more we study the distribution of over the Galois fields of degree 2 and use it to construct 2-dimensional, two-weight, self-orthogonal codes and constant weight codes over integers modulo prime.

Full textAbstract:
Objective: Adolescents with binge-eating disorder (BED) are suffering from weight teasing and, as found in adults with BED, are likely to internalize weight bias. Weight teasing by mothers accounts for psychopathology in overweight, but sources of stigmatization are largely unknown in BED. This study sought to address familial weight bias in adolescents with overweight and BED by examining adolescents’ perceived parental weight teasing and weight bias internalization in relation to their eating disorder psychopathology and maternal stigmatizing attitudes and beliefs.
Method: Adolescents with overweight and BED (BED; n = 40) were compared to a socio-demographically matched group with overweight only (OW) and a normal-weight control group (NW; each n = 25). They filled out the Perception of Teasing Scale, with parents as the source of teasing, the Weight Bias Internalization Scale and the Eating Disorder Examination-Questionnaire. Their mothers filled out the Attitudes Toward and Beliefs about Obese Persons Scales. Results: Significantly higher perceived parental weight teasing and weight bias internalization were found in BED compared to OW and NW. Maternal stigmatizing attitudes and beliefs did not differ between groups and were not correlated with adolescents’ perceptions of being stigmatized. Perceived parental weight teasing predicted adolescents’ eating disorder psychopathology, however, this association was fully mediated by weight bias internalization.
Discussion: These results indicate that adolescents with overweight and BED perceive weight teasing in their own families. As we found no significant association between adolescents’ perceptions of being stigmatized and maternal stigmatizing attitudes, future research should examine weight-related parent-child interaction or implicit measures of stigmatizing attitudes.

Full textAbstract:
The purpose of this study was to investigate the effects of different strength training modes on joint range of motion. The problem of the study was to compare Nautilus to free-weight training modes in terms of selected joints' ranges of motion before and after an eight-week strength training program. The hypothesis asserted was that there was no difference between pre-test and post-test scores when comparing Nautilus to free-weight training modes. Subjects were thirty college-age students enrolled in beginning weight-training classes at the University of the Pacific. The subjects were acquired from intact classes and comprised two groups of 9 males and 6 females each. Pre-test and post-test flexibility measures were acquired by use of a Leighton Flex-o-meter and sit-and-reach protocols. Single joint measures of shoulder flexion, extension and abduction, hip flexion, extension and abduction, elbow flexion, knee flexion, and low back flexion were acquired. For eight weeks, two times per week, each class completed an 8 to 12 repetitions per each exercise protocol following the principles of training asserted by Nautilus. Pre-test data for all bilateral joints were statistically analyzed with paired t-tests in order to determine any differences. No significant bilateral differences were found; consequently, these data were converted to eight single measures of average range of motion of the joints respectively. Pretest data then were analyzed with two-factor ANOV A (group x gender) in order to determine if the two intact classes initially represented the same population. The only measure in which a group difference was found was shoulder extension (p

Full textAbstract:
The birth and hospitalisation of a very low birth weight (VLBW; <1500 grams) infant is often extremely traumatic for parents. Mothers of VLBW infants experience significantly higher rates of posttraumatic stress symptoms (PTSS) than mothers of full-term infants two to three years postpartum (Åhlund, Clarke, Hill, & Thalange, 2009). A pilot study was conducted to examine self-reported PTSS in fathers of VLBW infants two to four years postpartum compared with fathers of term infants. Results were compared with the maternal data from the study by Åhlund et al. (2009). Additional data were collected on self-reported levels of anxiety and depression in fathers. Questionnaire packs containing the Impact of Events Scale-Revised, the Patient Health Questionnaire-9 and the Generalised Anxiety Disorder Seven Item Scale were posted to fathers of infants born two to four years previously. Fathers reported on PTSS relating to the birth and hospitalisation of their infant and current anxiety and depression symptoms. Perceived levels of social support at the time of the birth of their infant were also measured. Responses were received from 26 fathers of VLBW infants and 22 fathers of term infants. PTSS levels were significantly higher in fathers of VLBW infants than those of term infants U = 80.0, z = -4.31, p < .001 and PTSS levels did not significantly differ between fathers and mothers U = 222, z = -1.76, p = .079. There was a significant association between VLBW fathers’ levels of perceived social support and PTSS, but not with anxiety or depression. In conclusion, PTSS are found in fathers of VLBW infants two to four years postpartum and at similar levels to those found in mothers. Implications are discussed with particular reference to increasing psychological support for fathers following the birth of their VLBW infant and areas for further research are considered.

Sloan, Kevin C. "Examining Factors That Predict the Maintenance of Excess Weight Loss Two or More Years after Bariatric Surgery." Thesis, Northcentral University, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10807885.
Full textAbstract:
Bariatric surgery has demonstrated efficacy as a strategy to address morbid obesity and the comorbidities associated with this issue. Beyond two years there is an increased risk for weight regain and increases in Body Mass Index. Excess weight loss may impact quality of life and mental health status initially. Post-surgically, social support healthcare professional utilization is believed to influence excess weight loss success. Social contagion theory provides a model to explain and predict the impact of social networks on self-management. The purpose of this quantitative correlational study was to examine the relationships between social support quality, health quality of life, mental health status, and healthcare team support utilization on the maintenance of excess weight loss and BMI in post-bariatric patients beyond two years after surgery. A total of 34 participants completed the Multidimensional Perceived Social Support Scale, SF-36, and Depression, Anxiety, Stress Scale. The electronic health records of these patients were analyzed to determine utilization of healthcare professional support. Health quality of life was the only construct that demonstrated a statistical relationship with weight and BMI maintenance after two years (r = .46, p <.05; r =.47, p <.05). A significant negative correlation between quality of life and mental health status was found with both weight maintenance and BMI maintenance (r = -.62, p <.01; r = -.62, p <.01). There is limited research on long-term maintenance, but these findings are inconsistent with research which has found that social support, support utilization and mental health status may influence initial post surgical weight maintenance. A regression model found that the study variables are not predictive of the maintenance of weight and BMI beyond two years. These finding may contribute to research on weight maintenance in post bariatric patients beyond two years. The results should be viewed cautiously due to the low participation rate, which may have influenced statistical significance. Future research should examine the possible impact of weight gain on study participation, and may benefit from qualitative research methodology to determine themes associated with excess weight maintenance beyond two years.

Full textAbstract:
Colonies of the Big Brown Bat (Eptesicus fuscus) were located and studied in Blackford, Delaware, Grant, Henry, Jay, Madison, and Randolph Counties, Indiana, from June 12, 1988 through August 25, 1989. During the study, 24 colonies were located. Attempts were made to capture as many bats as possible during visits to the colonies. Colony sites were revisited several times during the two year study. A total of 1,846 bats were captured, banded and examined. During examinations bats were sexed, aged, weighed, and checked for wing damage and ectoparasites. The weights from the captured bats provided data on differences in bat weights for the summer of 1988 and 1989. The summer of 1988 was characterized by drier than normal precipitation, and the summer of 1989 had wetter than normal precipitation. Several comparisons were carried out on the data. The comparisons showed a correlation between increased rainfall and increased bat weights. In the wet year of 1989, adult bats were significantly heavier than they were in 1988. Juveniles were slightly heavier but not significantly. Further detailed data regarding age and sex ratios; wing damage and ectoparasite occurence are discussed briefly.Department of Biology

Full textAbstract:
Coupled two-dimensional HPLC systems were developed for the separation of complex sample matrices. Low molecular weight polystyrene oligomers were used as model compounds for the development of these systems since the sample dimensionality of oligostyrenes could be defined and classified according to two sample characteristics. That is, oligostyrenes could be classed as a two-dimensional sample, where one sample dimension is the variation in the number of monomers that make up oligomeric units determining the weight of the polymer, with a second sample dimension being the variation in stereoisomerism of each oligomer. During this study it was found that by combining two separation dimensions consisting of C18 and carbon clad zirconia (CCZ) phases separation of oligostyrenes according to molecular weight and stereochemistry was possible in coupled two-dimensional systems. The C18 phase separated the sample according to molecular weight, while the CCZ phase separated the sample according to the stereochemistry. The stereoisomer separations of the oligostyrenes reported on the CCZ surface were far superior to those previously reported in the literature. The efficiency of the separation process in a coupled two-dimensional system was then evaluated by studying the variation in band variance of a test probe. The results of the study indicated that the performance of a two-dimensional separation process was highly dependent upon the mobile phase compatibility, even when solvents were completely miscible and of similar polarities. Extracts from 17 species of Australian native plants were examined for xanthine oxidase inhibitory activity, the enzyme responsible for the formation of the disease gout. Chromatographic separation was conducted on plant extracts found to possess significant inhibitory activity against xanthine oxidase, with an extract from the species Clerodendrum floribundum R. Br. found to possess the greatest activity of the species examined. A two-dimensional separation of a crude extract from Clerodendrum floribundum R. Br. was conducted using one of the developed HPLC systems, to illustrate the use of such a system for the separation of a non-model complex sample mixtureDoctor of Philosophy (PhD)

Full textAbstract:
The objective of this study was to determine sheep production practices, constraints, flock dynamics, body condition and weight variation in two ecologically different resource-poor communal farming systems of the Eastern Cape Province of South Africa. Mean sheep flock sizes per household were not significantly different between the two ecologically different areas (villages); Gaga (19.0±3.10) and Sompondo (18.3±3.10). Shortage of feed, disease and parasite were reported the most important constraints across the two villages. In both villages, sheep housing was poorly constructed using acacia brushwoods. Fewer farmers owned rams: the rams to ewes ratio for the two villages were 1:20, 1:19 for Gaga and Sompondo, respectively. The low ram: ewe ratios reported suggest that inbreeding might have been reducing productivity of their flocks. There was also uncontrolled breeding due to undefined and mating seasons. Gall sickness, heart water and footrot caused most of the sheep mortalities. Dohne Merinos were the common genotypes in the two villages. Total entrances for each flock were higher (p < 0.05) in hot-dry season and hot-wet season than in other seasons. Most of the entrances were lambs and were born in hot-dry season (September) and cool-dry season (June) for larger flocks (10.90 ± 3.02) and for small flocks (3.65 ± 3.02). High lamb mortalities were experienced in the post-rainy (April) and hot-wet (December) season. There was a significant interaction between season and flock size. Most of the sales occurred in the hot-wet season. Ecological area had significant effect on sheep production potential (p < 0.05) in both flock classes. The average sheep production efficiency (SPE) value for Gaga and Sompondo were 0.50 ± 0.116 and 0.50 ± 0.096 respectively. The SPE for large flock was higher (p < 0.05) by season and flock size. Large flocks had a higher (p < 0.05) SPE values and the SPE ranged from 1.11 ± 0.193 in April, a post-rainy season month to 1.55 ± 0.193 in December, a hot-wet season month. Lamb mortalities constituted the greater part of outflows. High lamb mortalities occurred in hot-wet (December), hot-dry (September) and post-rainy (April) seasons. There was a significant interaction between season and age of sheep on body weight of sheep. Highest (p < 0.05) body weights were recorded in the post-rainy and autumn season in both lambs and ewes. It is therefore very important to come up with affordable interventions which take into play ecological differences of the areas for improved nutritional status of sheep in communal areas which will lead to improved sheep productivity and the poor-resourced farmer human nutritional and livelihood.

Here we present the genome-wide association study of body weight at 8 weeks of age based onthe advanced intercross pedigree of two chicken lines gone through bi-directional selection.With improved marker density (~3M SNPs) and larger sample size (2667 individuals from F2-F15), 34 loci with suggestive significance are detected, of which 18 loci are novel, and the rest17 loci are consistent with the results of previous quantitative trait locus mapping studies onthis trait with smaller number of genetic markers and fewer individuals. The component traits,referring to traits related to body weight and possibly contributing to the body weight as well,are also measured and analysed. The combined result showed that one locus with significantmarginal effect on BW8 is associated with early growth, breast muscle development and shankdevelopment, while another locus with late development and bursa development.

Full textAbstract:
There is conflict between recognized Strength and Conditioning professionals and organizations regarding the most effective methods of teaching the power clean weight training exercise. The area of greatest conflict is related to the effectiveness of whether to specifically introduce and segmentally practice the Double Knee Bend technique or not.
Sixty collegiate football players with novice power clean experience were randomly assigned to one of three groups: (1) a group in which the double knee bend technique was taught and practiced segmentally (DKB); (2) a group which was instructed in the same way as the DKB group except that the double knee bend was not specifically taught or practiced segmentally(NDKB), and (3) a control group (CG) which was exposed to an orientation session similar to the first two groups, but was not specifically instructed in the power clean technique.
Subjects in all three groups were video taped performing the power clean with a standardized weight both prior to and following a seven week training session. Each video taped trial was randomly assigned to an expert reviewer for qualitative analysis in a blind review. Reviewers rated the three upward movement phases as well as the total upward movement phase of the lift using a published check list and rated the performance from one to five with five being the best technique.
The result of the ANOVA and a Scheefe test showed that the two treatment groups both demonstrated significant improvement pre to post test in the power clean technique p<0.01. The control group did not significantly improve over the course of the same training period. In comparing the two treatment groups, the between groups analysis (DKB) and (NDKB) were not significantly different.
These results suggest that the double knee technique does not need to be specifically taught or segmentally practiced in order to improve power clean technique among college football players with novice power clean experience.Ed. D.

In this study, a biosurfactant producing culture enhancing dissolution of PAHs was isolated, to make them bioavailable. The culture was introduced to the system to improve the dissolution of PAHs and degrade the PAHs thereafter. The aim of the study was to use a strategy with a biofilm process, subsequent to a continuous stirred tank bio-reactors (CSTRs) to successfully remove PAHs from water, with microorganisms that can degrade these pollutants. The open system could easily be controlled and set to optimum conditions, stimulating the growth of PAH degraders. The feed rate and influent concentration can be controlled and the system can easily be cleaned. Biodegradation was achieved, using optimum conditions obtained from the conducted batch studies in a CSTR process ensuring a feasible biodegradation process. Two cultures, Pseudomonas aeruginosa and microbial consortia, were used during the biosurfactant production and PAHs degradation preliminary batch studies. The biosurfactants produced, were identified as Lipopeptides and degradation results indicated great degradation of fluoranthene and triphenylene with a mixed culture consortium present in the system. 90.1% of fluoranthene and 79.6% of triphenylene was degraded after 22 d of incubation in the batch system. Degradation of fluoranthene was studied using biosurfactants and microbial consortium in a three-stage continuous flow system. Reactor 2A fluoranthene influent (60.89%) was degraded, 70.02% of Reactor 2B fluoranthene influent was degraded and 77.17% of biofilm tank fluoranthene influent was degraded. Kinetic studies were conducted, using a Monod model to describe the substrates degradation for batch systems. The highest degradation rate for fluoranthene was determined to be 0.29 h-1 and for triphenylene was 0.13 h-1 with half saturation values of 991.84 mg/L and 451 mg/L respectively, indicating that fluoranthene was degraded faster than triphenylene, when incubated for 22 d. The study demonstrated that biosurfactant production and biodegradation of fluoranthene can be achieved in an open CSTR system, as much as it can be done in a batch system. The biological remediation of PAHs in wastewater plants can be introduced and applied for wastewaters rich, with PAHs.Dissertation (MSc)--University of Pretoria, 2017.

Background: There is paucity of local data on the profile of preterm very low birth weight (VLBW) infants who develop moderate to severe necrotising enterocolitis (NEC) and their outcomes. Methods: A retrospective folder review of VLBWs who developed Modified Bell’s stage II NEC or higher at Groote Schuur Hospital (GSH) nursery between January 2012 and December 2013 was performed. Outcomes were defined as requirement for surgery and mortality. Results: Forty seven infants were included (5% incidence). Gestational ages ranged from 25 to 36 weeks, 53% were 10 mg/L (60%) and subserosal gas radiologically (84%). Half the patients received mechanical ventilation, 38% required inotropes. The mortality rate was 64%. Three of the five infants that received surgery survived. Conclusion: Despite a similar incidence to global counterparts, our VLBW infants have severe NEC disease often requiring advanced life support, with a high mortality rate. HIV exposure may increase the risk of NEC development.

O objetivo deste trabalho foi desenvolver um modelo matemático que permita avaliar termodinamicamente equipamentos de secagem, por meio de balanço de massa e energia, elaborar diferentes compostos lácteos a partir da mistura de leite/soro, e avaliar o efeito de compostos de alta massa molar nas propriedades físico-químicas e de secabilidade de compostos lácteos tradicionais e sem lactose. Para a caracterização termodinâmica foi utilizado um spray dryer com atomizador de bico de pressão com capacidade de evaporação de 1 kg de água/hora (SD1) e um spray dryer com atomizador de disco, (com capacidade de secagem de 20 kg de água/hora (SD2). Para a elaboração dos compostos lácteos, foram utilizadas bases lácteas, deslactosadas ou não, elaboradas a partir de diferentes proporções de leite e soro, além de maltodextrinas 10 e 20 DE, inulina e fibra solúvel de milho. O modelo matemático foi válido para avaliação de perdas de massa e energia e permitiu comparar a eficiência entre secadores por aspersão com diferentes desenhos. O aumento no teor de soro nos compostos lácteos e principalmente a aplicação do processo de hidrólise da lactose reduziram tanto a qualidade dos pós (cor, temperatura de transição vítrea, higroscopicidade, etc..), quanto sua secabilidade (ocorrência de adesão, empedramento e maior gasto energético para evaporação da água). A adição dos compostos de alta massa molar apresentou efeito positivo sobre as propriedades físico-químicas e de secabilidade dos pós, sendo a maltodextrina, o composto mais eficiente.
The objective of this work is to develop a mathematical model that allows for thermodynamically evaluating of spray dryers through mass/energy balance, to elaborate products from mixing of the milk and whey and to evaluate the effect of compounds with high molecular weight in the physicochemical properties and drying characteristics of traditional and lactose-free dairy mixes. For the thermodynamic characterization, it has been utilized spray dryers with atomizer pressure nozzle (evaporation capacity: 1 kg of water/h) and with atomizer disc (evaporation capacity: 20 kg of water/h). For elaboration of the dairy mix, there have been used lactic bases (lactose containing and non-lactose containing bases), elaborated from different proportions of milk and whey, maltodextrin, inulin and soluble corn fiber. The mathematical model has been validated for the evaluation of mass and energy losses and allowed to compare the efficiency between spray dryers with different designs. The increase in whey content in dairy mix and, especially, the application of the lactose hydrolysis reduced both the quality of the powders (color, glass transition temperature, hygroscopy, etc) and drying properties (stickiness, caking and increased energy expenditure for water evaporation). The addition of the compounds with high molecular weight had a positive effect on the physicochemical properties and the drying of the powders, being maltodextrin the most efficient compound.

The purpose of this study was to assess athletic performance measures following two different loading conditions in the back squat exercise. Fourteen NCAA Division I tennis players were randomly assigned to either a low-resistance (50-60% of 1 repetition maximum [1RM]) training group or a high-resistance (65-90% 1RM) training group. The eight weeks of training consisted of 3 training sessions per week using a complete strength training program designed for sport performance enhancement. Performance in the 1RM back squat, 10 yard sprint and a countermovement vertical jump (CMJ) was assessed. There were no significant pretest to posttest differences in improving lower-body power production as measured by the 1 RM back squat, 10yd sprint and countermovement vertical jump in either group. The results of this study indicate that low-resistance, high-velocity training and high-resistance, low-velocity training is equally effective for improving lower-body power production.School of Physical Education, Sport, and Exercise Science

The purpose of this study was to examine the differences in the squat kinematics and kinetics while wearing two different types of footwear. Ten men that compete at a collegiate level of powerlifting participated in the study. The participants performed the squat in both Chuck Taylor (flat soled) and Adidas (raised heel) shoes 3 times per shoe at 80% of 1 RM. During the testing sessions, sagittal plane kinematics of the shank were measured using 2-D video analysis. A force plate was used to measure the ground reaction forces of the right foot. There was no significant difference (p>0.05) in the medial lateral ground reaction forces (raised heel 63.58 N, flat soled 65.79 N), or the shank angles (raised heel 67.4 degrees, flat soled 65.7 degrees) of the participants. In conclusion, the participants were able to accommodate for a 1 inch raised heel in their shoe without altering shank position of medial-lateral ground reaction forces.School of Physical Education, Sport, and Exercise Science

Full textAbstract:
The purpose of this study was to investigate two different plyometric training techniques for increasing vertical jumping ability. Twenty-four female high school volleyball players were matched for height and weight and distributed equally among three groups. Each subject performed a vertical jump test, Margaria power test, Wingate bicycle test, and an isokinetic leg strength test prior to and following six weeks of training. Plyometric training significantly (p<.05) improved vertical jumping ability and some indices of leg strength and power. Weighted plyometrics did not enhance performance more than plyometrics alone. These data support the view that plyometric training with or without added weights enhances vertical jumping and leg power.

Full textAbstract:
Background: Dopamine levels has been implicated in obesity, feeding behaviour, and hedonic control of appetite like olfactory cues and food palatability. Methylphenidate (MPH) is a dopamine reuptake inhibitor that increases brain dopamine levels and has been shown to reduce appetite and promote weight loss in patients with attention deficit hyperactivity disorder (ADHD). As such, the objectives of this study were to test the possible effect of MPH on appetite, olfaction, and food palatability as well as its effects on energy intake and body weight of healthy individuals with obesity.
Methods: In a randomized, double-blind study, 12 participants (age 28.9±6.7 yrs) (BMI 36.1±4.5 kg/m2) were assigned to receive MPH (0.5mg/kg) (n=5) or placebo (n=7) twice daily for two months. Appetite and palatability (Visual Analog Scale (VAS)), odour threshold (Sniffin’ Sticks®), in-lab energy intake (ad libitum buffet), free-living energy intake (3-day food boxes) and body weight (DEXA scan) were measured at baseline (day 1) and final visit (day 60).
Results: MPH intake caused significantly greater suppression of appetite sensations (desire to eat (p=0.001), hunger (p=0.008), and prospective food consumption (p=0.003)) and increase in fullness (p=0.028) over time compared to placebo. There was a significant increase in odour threshold scores in the MPH group (6.3±1.4 vs. 9.4±2.1) compared to placebo (7.9±2.3 vs. 7.8±1.9) (p=0.029). Both placebo and MPH groups showed decreases in their energy intake (p=0.021) and body weight (p=0.005) over time but with large effect sizes favouring greater reduction in the MPH group compared to placebo.
Conclusions: Compared to placebo, MPH intake over 60 days suppressed appetite and improved olfactory sensitivity in individuals with obesity. These data provide novel findings into the possible efficacy of MPH to favourably impact appetite and therefore promoting weight loss in individuals living with obesity.

Full textAbstract:
Contexte: Le retard de croissance intra-utérin (RCIU) désigne l’incapacité du fœtus à atteindre son potentiel de croissance déterminé génétiquement en raison de diverses causes. Il est défini le plus souvent par un poids de naissance inférieur au 10ème percentile pour l’âge gestationnel sur les courbes néonatales. Ce travail de thèse a comme objectif de répondre aux questions non-résolues sur la définition et les conséquences du RCIU dans le contexte de la grande prématurité: (1) Quelle est la meilleure définition du RCIU à utiliser pour identifier les enfants à risque ? (2) Quels sont les risques de mortalité et de morbidités néonatales respiratoires et neurologiques associés au RCIU et existe-t-il des interactions avec les pathologies de la grossesse responsables de cette naissance très prématurée ? (3) Quel est l’impact du RCIU sur le devenir neuro-développemental à 2 ans, en particulier chez les enfants nés extrêmement prématurément ? Méthodes: Nous avons utilisé deux sources de données. L’étude MOSAIC (Models for OrganiSing Access to Intensive Care for Very Preterm Babies in Europe) est une étude européenne en population qui porte sur l’ensemble des naissances survenues entre 22 et 31 semaines d’aménorrhée en 2003 dans dix régions européennes. Les enfants ont été suivis jusqu’à la sortie d’hospitalisation (population d’étude : 4525 enfants). La deuxième source est une cohorte d’enfants nés avant 27SA qui ont été hospitalisés dans le service de réanimation néonatale à l'hôpital de Port-Royal de 1999 à 2008 et qui ont eu un examen pédiatrique et une évaluation selon l’échelle de Brunet-Lézine qui inclut quatre domaines du développement global de l’enfant : la motricité globale, la motricité fine, le langage et l’interaction sociale (445 enfants admis, 268 enfants suivis à 2 ans). Résultats: Dans les deux populations, les risques de décès et de dysplasie broncho-pulmonaire étaient plus élevés pour les enfants ayant un poids de naissance <10éme percentile des courbes néonatales, mais également pour des enfants avec un poids plus élevé (entre le 10éme et le 24éme percentile des courbes néonatales ou <10ème percentile des courbes fœtales). Par contre, il n’y avait pas de lien entre les complications neurologiques et le faible poids, ni d’interaction avec les pathologies de la grossesse. Le RCIU était associé à un risque élevé du retard neurocognitif à deux ans d’âge corrigé chez les extrêmes prématurés, surtout dans le domaine de la motricité fine et de l’interaction sociale mais pas dans le domaine du langage et de la motricité globale. Nous n’avons pas trouvé d’association entre le RCIU et le risque d’infirmité motrice cérébrale à deux ans d’âge corrigé. Conclusions: L’utilisation du 10ème percentile des courbes néonatales n’est pas adaptée pour identifier l’impact du RCIU chez les grands prématurés ; l’utilisation de multiples seuils ou de courbes de croissance fœtale est nécessaire. Le RCIU accroit les risques de mortalité et de dysplasie broncho-pulmonaire, mais n’est pas associé aux lésions cérébrales sévères ; ces associations sont observées dans différents contextes périnatals (pathologies vasculaires et infectieuses, et naissances à des âges gestationnels très précoces). Le RCIU représente un facteur pronostic défavorable pour le neuro-développement à moyen terme. Nos résultats soulèvent de nouvelles questions sur le suivi adapté pour les enfants ayant un RCIU après leur sortie de l’hôpital et aussi sur les éventuels mécanismes biologiques pouvant expliquer les liens entre le RCIU avec une morbidité respiratoire et certains domaines du développement neurocognitif à moyen termeBackground: Intrauterine growth restriction (IUGR) refers to the inability of the fetus to achieve its genetically determined growth potential due to various causes. Most often, it is defined by a birth weight less than the 10th percentile for gestational age using neonatal growth curves. This thesis aims to answer unresolved questions about the definition and consequences of IUGR in the context of very preterm birth: (1) what is the best definition of IUGR for identifying children at risk? (2) What are the risks of mortality and neonatal respiratory and neurological morbidity associated with IUGR and are there interactions with the underlying pregnancy complications responsible for the very preterm birth? (3) What is the impact of IUGR on neurodevelopmental at 2 years, especially for children born extremely preterm ? Methods: We used two data sources. The MOSAIC study (Models for Organising Access to Intensive Care for Very Preterm Babies in Europe) is a European population-based study that included all births occurring between 22 and 31 weeks of gestation in 2003 in ten European regions. The children were followed until hospital discharge (study population = 4525 infants). The second source is a cohort of children born before 27 weeks of GA who were hospitalized in the neonatal intensive care unit at the Port Royal Hospital from 1999 to 2008 and had a pediatric examination and Brunet-Lézine (BL) neurodevelopmental assessment at 2 years of corrected age (445 children in the cohort, 268children followed at 2 years). The BL assessment includes four areas of child development: gross motor, fine motor, language and social interaction skills. Results: In both populations, the risk of death and bronchopulmonary dysplasia were higher for children with a birth weight <10th percentile of neonatal growth curves but also for children with a higher birth weight (between the 10th and the 24th percentile of neonatal growth curves or <10th percentile of fetal growth curves). In contrast, there was no link between neurological complications and low birth weight and no interactions with pregnancy complications. IUGR was associated with neurocognitive delay among extremely preterm children evaluated at two years of corrected age, especially for fine motor and social interaction skills, but not for language and gross motor skills. We did not find any association between IUGR and the risk of cerebral palsy at two years of corrected age. Conclusions: The use of the 10th percentile of neonatal growth curves is not suitable for identifying the impact of IUGR in very preterm infants; using higher thresholds or fetal growth curves is necessary. IUGR increased the risks of mortality and bronchopulmonary dysplasia, but was not associated with severe brain damage; these associations are observed in multiple clinical contexts (vascular and infectious pregnancy complications, and births at very early gestational ages). IUGR is a risk factor for poor medium-term neuro-development. Our results raise new questions about the appropriate surveillance for children with IUGR after discharge from the hospital and also about possible biological mechanisms that could explain the relationship between IUGR and respiratory morbidity and neurocognitive development

Full textAbstract:
Publikationen die in letzter Zeit veröffentlicht wurden zeigten den G Protein-gekoppelte Rezeptor 30 (Gpr30) als neuer potenzieller Östrogen Rezeptor. Dieser Befund wird kontrovers diskutiert, zudem wurde die physiologische Funktion von Gpr30 bisher noch nicht vollständig geklärt. Ziel der vorliegenden Arbeit war die Erforschung der Rolle von Gpr30 in vivo. In einer primären und sekundären Untersuchung wurde eine phänotypische Charakterisierung einer Gpr30-defizienten Mauslinie vorgenommen. Diese Mauslinie wurde generiert, indem eine beta-Galactosidase-Neomycin Vektorkassette in den open reading frame des Gpr30 Gens eingesetzt wurde. Im Rahmen der primären Untersuchung zeigte die immunologische Analyse eine Reduzierung der T-Zellen sowohl bei den männlichen als auch bei den weiblichen mutanten Mäusen. In einer Thymus-Genexpressionanalyse konnten einige Gene identifiziert werden, die möglicherweise in der Regulation der Anzahl an T-Zellen involviert waren. Auf der Grundlage dieser Ergebnisse wurde eine Erhöhung der Kalzium-vermittelten T-Zellen Apoptose hypothetisiert. Gegenstand der sekundären Untersuchung war die Bestimmung eines möglichen metabolischen und kardiovaskulären Phänotyps, da Gpr30 überwiegend in den Blutgefäßen verschiedener Organe, sowie in der Pankreas und im Magen exprimiert ist. Zu diesem Zweck wurden die Mäuse einer Hochfettdiät unterzogen und es wurden metabolische sowie hemodynamische Tests durchgeführt. Um den Phänotyp dieser ersten Mauslinie zu bestätigen, wurde eine zweite Mauslinie ohne Selektionsmarker generiert. Insgesamt tragen die Ergebnisse der vorliegenden Studie zu einem besseren Verständnis der Funktion von Gpr30 in vivo bei. Eine Rolle des Rezeptors bezüglich der Regulation des Körpergewichts konnte widerlegt werden, während ein Einfluss auf den Lipid- und Muskelstoffwechsel angenommen werden kann. Zudem wurde gefunden, dass Gpr30 für einige Östrogen-regulierende, physiologische Prozesse nicht erforderlich ist.Recent studies identified the G protein-coupled receptor 30 (Gpr30) as a potential new estrogen receptor. However, these findings remain still controversial and the physiological role of Gpr30 has not been clarified yet. In order to decipher the role of Gpr30 in vivo, we investigated the phenotype of a Gpr30 mutant mouse line, generated by the insertion of a beta-galactosidase-neomycin cassette into the Gpr30 open reading frame, in a primary and a secondary screen. The primary screen revealed a decrease of T cell levels in both male and female mutants. Thymus gene expression analysis allowed to detect some of the genes potentially involved in regulating T cell levels in these mice. On this basis a hypothesis of an increase in T cell calcium-mediated apoptosis was formulated. The secondary screen aimed at unraveling a potential metabolic and cardiovascular phenotype, being Gpr30 mainly expressed in the vasculature of several organs, as well as in the pancreas and in the chief gastric cells of the stomach. Therefore, mice were challenged with a defined high fat diet, and metabolic and hemodynamic tests were performed. To confirm the phenotype achieved in this first mouse line, a second one, devoid of any selection marker, was analyzed. Altogether the results achieved may contribute to a better understanding of Gpr30 function in vivo, disproving a role of Gpr30 in body weight regulation, suggesting a role in lipid and muscular metabolism, and providing evidence that Gpr30 may not be required for several estrogen-regulated physiological processes.

Essay 1: By using the data of the 2001 National Health Interview Survey of Taiwan, this study investigates the empirical association between education and effective weight control. It uses a univariate probit model to assess the difference in this relationship for young and old cohorts. Our results indicate that education has positive influence on effective weight control, but women''s education needs time precipitation absorption, and the influence of education on the decision of weight control for men is greater than that for women. It also attempts to use a bivariate probit model to assess the difference in the relationship, controlling for the potential endogeneity of overweight or education, by using genetic instrumental variables. It tests the hypothesis that overweight is exogenous and the hypothesis that education is exogenous in the equation of effective weight control,. Both hypotheses are supported. Essay 2: The economic effects of obesity on employment have received an increasing attention; nonetheless, none of the previous studies has taken the intention of weight control, which is often unobserved in many relevant data sets, into account. By using the data of the 2001 National Health Interview Survey of Taiwan, this study investigates whether the intention of weight control is a key factor for mitigating the punishment of obesity, in terms of smaller negative effect on employment, for young workers. It uses a trivariate probit model to assess the change in this relationship, controlling for the potential endogeneity of obesity, by using genetic instrumental variables, for young workers. It shows that the absolute value of negative marginal effect of obesity on employment is smaller for young workers who intend to do weight control to reduce weight than those who do not.

Since transmission technologies of variety of multimedia services, such as data, voice, video, have made great progress recently, using bandwidth efficiently and providing different transmitting rates and qualities of these multimedia services turn into an important research topic. In this thesis, we combine the methods of code-weight variation and power control in order to provide differential quality-of-service (QoS) in multimedia optical code-division multiple access. An approximation model of performance analysis is developed to investigate the interaction of both methods. For illustration, we focus our study on double-weight codes with different bit powers. Our results show that the QoS of double-weight codes can be fine-tuned by controlling both code weight and bit power. Finally, we formulate a procedure for users to select code weights and bit powers in accordance with targeted code performances or the number of transmitting codes.

Zhu, Yibo. "Two-dimensional material-based nanosensors for detection of low-molecular-weight molecules." Thesis, 2018. https://doi.org/10.7916/D8BK2QVN.
Full textAbstract:
Low-molecular-mass small molecules play important roles in biological processes and often serve as disease-related biomarkers for diagnosis. Accurate detection of small molecules remains challenging for conventional sensors due to their limited sensitivities. Two-dimensional (2D) materials, thanks to their atomic level thickness, can be extraordinarily sensitive to external perturbations and therefore well-suited for sensing applications. This dissertation explores the use of 2D materials, including primarily graphene and transition metal dichalcogenides, in the detection of low-molecular-weight and low-charge molecules.
This work starts with the study of methods that allow for efficient and clean transfer of graphene grown on Cu using chemical vapor deposition (CVD), which is a critical step for achievement of large-area and high-quality graphene for device fabrication. In addition to the conventional wet-etching transfer method, we have studied on the method of electrochemical delamination, which is more time-efficient and allows for recycling of the Cu foil. Generation of bubbles during the electrochemical reaction is minimized by tuning the experimental parameters, thereby minimizing transfer-induced damages to graphene.
We then fabricate the graphene-based field effect transistor (FET) and use the graphene FET as biosensors. First, the sensor is configured as an electrolyte-gated FET. With appropriate biochemical functionalization of the graphene, the FET sensors have been used to detect multiple small-molecule biomarkers including glucose and insulin via their affinity binding with receptors. Then, on a flexible substrate, we demonstrate real-time measurement of tumor necrosis factor alpha, a signal protein that regulates immune cells. We then simplified the sensor structure using a bottom local-gate to replace the external electrode as required in the previous electrolyte gated FET. Using the bottom local-gated FET sensor we have carried out real-time monitoring of the variation of pH in solutions.
In addition to the electrical sensors, highly sensitive and multifunctional plasmonic sensors have also been developed by combining the unique optical properties of graphene with engineered metallic metasurfaces. The plasmonic sensors operating in mid-infrared region are configured as either metallic metasurface or hybrid graphene-metallic metasurface. Using a metallic metasurface, we demonstrate simultaneous quantification and fingerprinting of protein molecules. Using a hybrid graphene-metallic metasurface, we demonstrate optical conductivity-based ultrasensitive biosensing. In contrast to refractive-index-based sensors, the sensitivity of the hybrid metasurface sensor is not limited by the molecular masses of analytes. A monolayer of the sub-nanometer chemicals can be readily detected and differentiated on the hybrid metasurface. Reversible detection of glucose is carried out via the affinity binding of glucose with boronic acid immobilized on the graphene of the hybrid metasurface. The lowest detection limit achieved in our work is 36 pg/mL, which is considerably lower than that for the existing optical sensors.
Despite the high sensitivity of graphene, the zero band-gap of graphene fundamentally impedes its use in digital electronic devices. In contrast, two-dimensional semiconductors, such as transition metal dichalcogenide (TMDC) with non-zero band gaps, holds great potential for developing practical electronic devices and sensors. Monolayers of TMDC materials are particularly attractive for development of deeply scaled devices, although the contact resistance between metal and the monolayer TMDC has been so large to significantly limit the performance of the devices. We present a high-performance monolayer MoS2 FET with a monolayer graphene as bottom local gate. The graphene gate is found to significantly improve the dielectric strength of the oxide layer compared to the lithographically patterned metal gate. This in turn allows for the use of very thin gate dielectric layer (~5 nm) and application of a strong displacement field to lower the contact resistance. Benefiting from the low contact resistance, the monolayer MoS2 FET offers a high on/off ratio (108) and low subthreshold slope (64 mV/decade). Additionally, thanks to the highly efficient electrostatic coupling through the ultrathin gate dielectric layer, short-channel (50 nm and 14 nm) devices are realized that exhibit excellent switching characteristics.
In summary, this dissertation presents significant contributions to 2D material-based electronic and optoelectronic nanosensors, especially for detection of small molecules. Perspectives are made in the end of the thesis, on future studies needed to realize practical applications of these sensors and other 2D material-based products.

The ultradrawing behavior of gel films of plain ultrahigh molecular weight polyethylene (UHMWPE) and UHMWPE / low molecular weight polyethylene (LMWPE) blends was investigated using one- and two-stage drawing processes. The drawability of these gel films was found to depend significantly on the temperatures used in the one- and two-stage drawing processes. The critical draw ratio (c) of each gel film prepared near its critical concentration was found to approach a maximum value, when the gel film was drawn at an “optimum” temperature ranging from 95 to 105℃. At each drawing temperature, the one-stage drawn gel films exhibited an abrupt change in their birefringence and thermal properties as their draw ratios reached about 40. In contrast, the critical draw ratios of the two-stage drawn gel films can be further improved to be higher than those of the corresponding single-stage drawn gel films, in which the two-stage drawn gel films were drawn at another “optimum” temperature in the second drawing stage after they had been drawn at 95℃ to a draw ratio of 40 in the first drawing stage. These interesting phenomena were investigated in terms of the reduced viscosities of the solutions, thermal analysis, birefringence and tensile properties of the drawn and undrawn gel films.

The purpose of this study was to determine the effects of following either the Curves® Fitness and Weight Management Plan or the Weight Watchers® Momentum™ Plan on body composition and markers of health and fitness in previously sedentary obese women. Fifty-one women (age 35±8 yrs; height 163±7 cm; weight 90±1 kg; BMI 34±5 kg/m2; 47±7% body fat) were randomized to participate in the Curves® (C) or Weight Watchers® (W) weight loss programs for 16-wks. Participants in the C group (n=24) followed a 1,200 kcal/d diet for 1-wk; 1,500 kcal/d diet for 3 wks (~30%:45% CHO:PRO); and 2,000 kcals/d for 2-wks (45:30) and repeated this diet while participating in a supervised Curves® with Zumba program 3-d-wk. Remaining subjects (n=27) followed the W point-based diet program, received weekly group counseling, and were encouraged to exercise. Body composition, anthropometrics, resting energy expenditure (REE), lipid biomarkers, and hormone concentrations were assessed at 0, 4, 10, and 16 weeks. Maximal cardiopulmonary exercise capacity and upper and lower body isotonic strength and endurance were assessed at 0 and 16 weeks. Data were analyzed using multivariate analysis of variance for repeated measures.
MANOVA analysis of body composition data revealed overall time (Wilks’ Lamda p=0.001) and time by diet effects (Wilks’ Lamda p=0.003). Subjects in both groups lost a similar amount of total mass (C -2.4±2.0, -4.1±3.4, -5.1±3.9; W -2.3±2.3, -4.5±3.0, -5.5±4.6 kg, p=0.78). However, subjects in the C group tended to have a greater reduction in percent body fat (C -3.3±5.2, -3.2±4.6, -4.7±5.4; W 0.6±6.7, -0.6±8.3, -1.4±8.1%, p=0.10) and body fat mass (C -3.9±5.5, -4.6±5.3, -6.4±5.9; W -0.4±5.7, -2.1±6.7, -2.9±7.8 kg, p=0.09), while maintaining FFM (C 1.5±4.3, 0.52±3.7, 1.3±4.0; W -1.8±5.4, -2.4±5.8, -2.5±5.1, p=0.01). While both groups had increases cardiovascular fitness, the C group experienced improvements in upper body muscular endurance (C 1.4±3.9; W -1.2±2.4 repetitions, p=0.006). Both groups experienced improvements in lipid biomarkers; however, only the C group experienced a moderate increase in HDL-c. Results indicate that participants following the C program experienced more favorable changes in body composition and markers of fitness and health than participants in the W program.

With the rapid growth in Taiwan’s cash card market, banks need to investigate customers’ credit histories before issuing cash cards and approving credit limits. In order for banks to make more precise judgments and better decisions, an automatic and scientific evaluation model about customers’ credit rating should be integrated into a simplified rating process, so that applications for cash cards can be processed quickly and accurately to reduce loss from bad debt. This research focuses on building up an evaluation model comprising risk variables affecting cash cards. A Genetic Algorithm characterized with multi-point searching power is employed to analyze and resolve the issue regarding two-level weight parameters of risk variables of cash card. The subjects studied are customers from a specific bank involved in the cash card business. A total of 1398 subjects were sampled in this study, 1276 of them pay on time, and the others pay after the due date. Through analyzing empirical data, it’s expected to set up an evaluation model comprising two level risk variables affecting cash cards. The higher rating scores you make, the lower risk you have. As the research shows, the first level weight parameters of risk variables affecting cash cards ranked in order of highest to lowest risk are home ownership, education background, annual income, marital status, gender, credit balance, credit records and finally age. The second level variables of low risk are: females, those are earning an annual income between 300,000 to 500,000 NT dollars, holding a high school diploma, divorced or living with a live-in boyfriend or girlfriend, being a homeowner without loans, paying by credit cards or checks for over one year, under three years and without bad credit records, as well as maintaining a credit balance over 1,000,000 NT dollars. Another important finding is that those aged 46 to 55 have the lowest credit risk, and those 55 years and older second in low credit risk. By identifying potential risks and taking preventive measures, the goal to reduce risks for cash cards can be eventually achieved. In addition, appropriate management and oversight in the application process, as well as reviews after the cash cards have been issued and follow-up improvements are also critical steps to carry out such a goal. In conclusion, this research builds up a model combining the statistical method and information technology, offering solutions to enhance efficiency, reduce costs and above all optimize profits.
