Item Restricted Evaluating Factors Affecting Construction Labor Productivity in Mass Timber Building Projects(Oregon State University, 2024-07-26) Alotaibi, Nawaf Obaid L; Arocho, IngridMass timber is a sustainable building material that is gaining popularity in the US construction industry as an alternative to the conventional materials such as concrete and steel. The increasing number of mass timber projects indicates the ongoing recognition of its benefits including its structural performance, faster construction time, environmental sustainability, and aesthetic appeal. However, despite its advantages, the factors influencing construction labor productivity (CLP) in mass timber projects have not been investigated. This research aims to identify and evaluate factors affecting CLP in mass timber construction from the perspective of construction professionals in the U.S. Understanding the factors affecting productivity helps construction practitioners and researchers to enhance efficiency of projects, which in turn positively influence the construction productivity growth. To achieve the aim of this research, a literature review was conducted to identify factors affecting CLP, followed by a survey questionnaire that was distributed to construction professionals in the US construction industry to evaluate the identified factors and determine their influence on labor productivity in mass timber projects. The survey results were analyzed using the Relative Importance Index (RII) to rank the factors based on their importance. The study revealed that the degree of collaboration and communication among project parties is the most important factor influencing CLP in mass timber projects. Other important factors include the adequacy of planning and risk management, competency in labor supervision and management, design complexity, assembly system, and the need for specialized skills and training. The study also identified several challenges perceived by professionals in achieving high labor productivity including coordination and planning issues, training and experience, material and logistical challenges, design challenges, adoption of mass timber, and environmental issues. Additionally, the study identified current practices and provided recommendations for enhancing mass timber productivity. The results of this research will contribute to the construction industry by highlighting areas that need improvement to achieve better project outcomes. By addressing these factors and challenges, construction practitioners can enhance labor productivity, reduce project timelines, and improve overall project efficiency in mass timber construction. This research offers valuable insights for the current construction industry and establishes a foundation for future advancements in adopting mass timber as a mainstream building material in the U.S. construction industry.18 0Item Restricted An audit of current recall rates and contributing factors in the MRI department at a private medical facility(University of Dublin, 2023-12-14) Al safwan, Alia; Mcgee, AllisonObjective: This audit aims to improve the quality of the MRI department by determining the recall rate for MRI examinations and analysing the contributing factors. Duration and Place of Audit: This audit was conducted between September 2022 and August 2023 at a private medical facility. Material and Methods: Data were collected retrospectively for the recall of all MRI examinations. The data collected contained the total of MRI examination recall, types of MRI examination recall, the period between the initial and recall MRI examination and identified causes of recall. Results: Thirty-nine MRI examinations were recalled between September 2022 and August 2023; the recall rate was 0.68% (39/5694), averaging 3.2 MRI examinations recalled monthly. Due to recalls, there was a delay in MRI examination reports in 0.52% (30/5694) of outpatients and 0.052% (3/5694) of inpatients. The highest MRI examination recall types were the MRI brain at 20.5% (8/39), and the MRI female pelvis at 15.3% (6/39). Eight various contributing factors caused the recall with a total of 50 factors across all the MRI examination recalls. The main causes were the requirement of additional imaging post-gadolinium-based contrast agent (GBCA) administration by 42% (21/50) and further sequence types by 32% (16/50). Conclusion: The MRI examination recall rate was very low. In addition, the main MRI examination recalls cause was additional images post-GBCA administration. However, the MRI examination recall can be prevented by following certain strategies.24 0Item Restricted The Most Important Factors Influencing Customers’ Satisfaction in The Saudi Medical Insurance Sector(Saudi Digital Library, 2023-09-27) Aldofar, Abdulaziz; Garvey, JohnThis thesis studies the most critical factors influencing customers' satisfaction with Saudi medical insurance. It aims to understand the influences that affect customers' satisfaction to help Saudi insurance companies develop their medical insurance products and meet their needs. It focuses on ranking the factors (medical networks, e-services, customer services, and medical approvals) according to their impact on the client's satisfaction and examining their satisfaction level with each factor. This study assumes that there are preferences among these factors and apparent satisfaction with each factor. The data were collected by a questionnaire that included mixed methods and shared with participants through social media. The study found that the ranking of these factors is (medical networks, quick medical approvals, e-services, and customer services). Finally, the results also found a state of satisfaction with all factors except customer services, which is neutral.16 0
