PREDICTING CARPAL TUNNEL PRESSURE: AN ERGONOMIC TOOL TO PREDICT CARPAL TUNNEL SYNDROME RISK

Weresch, Justin A. 10 1900 (has links)
<p>A model to predict carpal tunnel syndrome (CTS) risk would improve ergonomic assessments and help reduce the incidence of occupational CTS and its associated costs. Research spanning over sixty years has shown that deviated wrist, forearm, and hand posture has on the hydrostatic pressure within the carpal tunnel (also known as carpal tunnel pressure, CTP). Elevated CTP is a mechanism of the development, or aggravation of CTS symptoms. The purpose of this thesis was to develop a model to predict CTS risk, based on CTP, and incorporate the model into an ergonomic tool for use by ergonomists. An extensive literature review identified additional studies that investigated the effects of pronation/supination, finger posture, and fingertip loading on CTP. The effect of wrist, forearm, and hand posture was then incorporated into the model via a series of regression equations developed for each plane of movement. The effect of fingertip loading (independent to the posture effects) was included using a multiplier based on the hand posture and load magnitude. To provide a user-friendly tool for ergonomists, a graphical-user-interface was developed to predict CTS risk based on the developed model. Input variables were wrist, hand, and forearm posture, and fingertip loading. CTP program estimated CTP, and compared the predicted pressure to a known threshold beyond which median nerve function has been shown to degrade. The tool was then evaluated by comparing the output of the tool (CTS risk) to the incidence of CTS in a large automotive manufacturing environment. There was no significant difference between the two groups (workers completing jobs with an incidence of CTS and workers completing jobs with no incidence of CTS). The tool marks an important first step v towards providing ergonomists with a much-needed tool to predict CTS risk based on posture, frequency, and fingertip force.</p> / Master of Science (MSc)

Salvage and de novo synthesis of nucleotides in Trypanosoma brucei and mammalian cells

Fijolek, Artur January 2008 (has links)
All living cells are dependent on nucleic acids for their survival. The genetic information stored in DNA is translated into functional proteins via a messenger molecule, the ribonucleic acid (RNA). Since DNA and RNA can be considered as polymers of nucleotides (NTPs), balanced pools of NTPs are crucial to nucleic acid synthesis and repair. The de novo reduction of ribonucleoside diphosphates (NDPs) to deoxyribonucleoside diphosphates (dNDPs), the precursors for DNA synthesis, is catalyzed by the enzyme ribonucleotide reductase (RNR). In cycling cells the dominant form of mammalian RNR consists of two proteins called R1 and R2. A proteasome-mediated degradation completely deprives postmitotic cells of R2 protein. The nonproliferating cells use instead a p53 inducible small RNR subunit, called p53R2 to synthesize dNTPs for mitochondrial DNA replication and DNA repair. To address the ongoing controversy regarding the localization and subsequently function and regulation of RNR subunits, the subcellular localization of all the mammalian RNR subunits during the cell cycle and after DNA damage was followed as a part of this thesis. Irrespective of the employed methodology, only a cytosolic localization could be observed leading to a conclusion that the dNTPs are synthesized in the cytosol and transported into the nucleus or mitochondria for DNA synthesis and repair. Thus, our data do not support the suggestion that nuclear translocation is a new additional mechanism regulating ribonucleotide reduction in mammalian cells. In an attempt to find a cure for African sleeping sickness, a lethal disease caused by a human pathogen, Trypanosoma brucei, nucleotide metabolism of the parasite was studied. The trypanosomes exhibit strikingly low CTP pools compared with mammalian cells and they also lack salvage of cytidine/cytosine making the parasite CTP synthetase a potential target for treatment of the disease. Following expression, purification and kinetic studies of the recombinant T. brucei CTP synthetase it was found that the enzyme has a higher Km value for UTP than the mammalian CTP synthetase. In combination with a lower UTP pool the high Km may account for the low CTP pool in trypanosomes. The activity of the trypanosome CTP synthetase was irreversibly inhibited by the glutamine analog acivicin, a drug extensively tested as an antitumor agent. Daily injections of acivicin to trypanosome-infected mice were sufficient to suppress the parasite infections. The drug was shown to be trypanocidal when added to cultured bloodstream T. brucei for four days at 1 uM concentration. Therefore, acivicin may qualify as a drug with “desirable” properties, i.e. cure within 7 days, according to the current Target Product Profiles of WHO and DNDi. Trypanosomes lack de novo purine biosynthesis and are therefore dependent on exogenous purines such as adenosine that is taken up from the blood by high-affinity transporters. We found that besides the cleavage-dependent pathway, where adenosine is converted to adenine by inosine-adenosine-guanosine-nucleoside hydrolase, T. brucei can also salvage adenosine by adenosine kinase (AK). The efficient adenosine transport combined with a high-affinity AK yields a strong salvage system in T. brucei, but on the other hand makes the parasites highly sensitive to adenosine analogs such as adenine arabinoside (Ara-A). The cleavage-resistant Ara-A was shown to be readily taken up by the parasites and phosphorylated by the TbAK-dependent pathway, inhibiting trypanosome proliferation and survival by incorporation into nucleic acids and by affecting nucleotide levels in the parasite.

Modely zlepšování procesů testování softwaru a zajištění kvality / Test process improvement and software quality assurance models

Došek, Tomáš January 2012 (has links)
Testing often takes between 35 and 50 percent of the total costs of software development projects. Still, the role of testing tends to be underestimated. High costs that are being spent on software testing make a reason for looking for systematical approaches for making the testing processes efficient. Test process improvement models offer such approaches. These models are subject of this thesis. Implementation of process improvement models can be an expensive, long-term activity. Therefore, reasons need to be found, why is important to use such models. Reasons and motivations for using improvement models are demonstrated in the first part of this thesis. It turned out that software testing has, by its historical development, come to the state, when it contains so much theory that companies have a problem absorbing all the knowledge to make testing processes efficient. Therefore, improvement models offer a solution to this problem. This thesis is primarily focused on Test Maturity Model Integration (TMMi), which is being analyzed thoroughly. The work searches for possibilities and limitation of using the model and it summarizes current experiences with the model. Because the TMMi model does not contain a practical assessment method, such method is proposed in this thesis. The assessment method will help organizations using the model. Beside TMMi, the thesis provides an introduction into three other models: Test Process Improvement (TPI), Capability Maturity Model Integration (CMMI) and Critical Testing Processes (CTP). All four models are subject to a comparison based on specified criteria. Results of the comparison are analyzed to identify for which situations individual models suit best. The comparison will help organizations to choose the right model for their needs.

The Evolution of Cash Programming in Nepal: Implementing Agencies' Perspectives

Sharma, Prabin 05 1900 (has links)
Cash assistance has emerged as a vital tool for supporting household recovery in Nepal after multiple disasters, including the 2015 earthquake, 2018 drought, and COVID-19 pandemic. This research engages with organizational learning theory to explore how cash programs evolved overtime and identify the challenges and opportunities encountered in program implementation. Using semi-structured interviews, I recorded the experiences of individuals from NGOs, INGOs, and donor agencies involved in managing these programs in Nepal. While initial skepticism from the government, limited resources, and beneficiaries' lack of access to financial institutions presented obstacles, cash programs empowered individuals to meet their needs and revitalized local economies. The research identifies that technological integration, use of market analysis, and collaboration with financial institutions as evidence of learning from past programs to inform new programs; however, government resistance remained a barrier. Interview participants emphasized the importance of collaboration, innovation, and adaptation to improve future cash programs and, build a more resilient Nepal that is better prepared for future disasters.
