    3D printed nanocomposite parts for improved dental recovery of decayed teeth
    (Association for Industry, Engineering and Management Systems (AIEMS), 2021-12) Miller, Lateefah; Rahman, Muhammad M.; Asmatulu, Ramazan
    Bone regeneration and tooth recovery processes have been gaining much popularity and becoming a feasible process worldwide. This process is also called bone scaffolding and grafting where grafted bones are surgically placed to the section of the bone/tooth for repair. Recently, the 3D printing technology has been a great interest in research on bone and tissue repair with the use of 3D printed parts; however, research in dental repair has seen very little interest. In the U.S., adults have an average number of 3.28 decayed or missing permanent teeth and 13.65 decayed and missing permanent surfaces. Meanwhile, dental costs are a significant barrier to adults aged 20-64 maintaining good oral and dental health. Most healthcare plans will cover all basic dental exams, but typically only pay up to half of the cost of major procedures such as crowns and inlays. This research is focused on creating a means of producing permanent dental repairs using the 3D printing process. The 3D printed parts include biodegradable polymers, hydroxyapatite particles, and mechanical testing parts. It is expected that this process will drastically lower costs compared to the conventional tooth recovery processes by limiting the dental operations and dentist visits.

    The pandemic lockdown impact on employees in Saudi Arabia
    (Association for Industry, Engineering and Management Systems (AIEMS), 2021-12) Qawarish, Ali M.; Bakhsh, Ahmed A.
    Once COVID-19 lockdown was activated in most countries, people had started to suffer the consequences, among those were employees who are considered one of the important society segments as an engine of economic growth during the pandemic. In this regard, this study employs structural equation modeling (SEM) to determine the impact of COVID-19 lockdown on private sector-employees in Saudi Arabia based on a sample targeting the lockdown period using a survey consisting of three main domains to be measured: physical, psychological, and financial. The correlations between the study variables are within the acceptable range. Confirmatory Factor Analysis (CFA) was conducted using AMOS software to validate each domain construct. The results provide support for the hypothesized model with significant internal consistency reliability for each domain. The estimated model reveals that the lockdown exerted a considerable influence on various aspects of employees' life which therefore may impact their performance in their organizations later. The findings can help guide decision-makers within the business community regarding internal customers' needs and also help governments gain a better understanding of citizens' emotions, issues and, interests during critical times.

    Examining Part 141 flight training: Flight hours and days to instrument rating
    (Association for Industry, Engineering and Management Systems (AIEMS), 2021-12) Wheeler, Brooke; Mumfrey, Jessica; Dolan, Drew
    Understanding the efficiency of flight training in collegiate programs is essential as Part 141 training aims to create safe pilots with lower training times. The purpose of this study was to determine whether there is a relationship between the total flight hours and the total calendar days it takes to complete the FAA Part 141 instrument flight training course. We used a correlational design to analyze the relationship between the variables; the records used were those who had enrolled in the instrument course and successfully passed the instrument check ride. Examining the Part 141 flight school records at a collegiate program, we found a medium, positive correlation between total calendar days in the course and flight hours to instrument rating.

    Everybody wins when more women are in the transportation industry
    (Association for Industry, Engineering and Management Systems (AIEMS), 2021-12) Drawe, Kristie; Zoghi, Behbood
    The objective of this paper is to provide an analysis and evaluation of the current workplace landscape on gender equity, culture and support, career advancement opportunities, perceptions on gender demographics, and how they relate to company success and a more user-friendly transportation system. The main method of analysis compared responses collected from transportation professionals and university students with an interest in transportation. While the survey responses show that both professionals and students recognize that organizations would benefit from a more equitable workplace and that my additional literature review demonstrates the positive return on investment of a more equitable workspace, the data shows women feel that gender equity has not been achieved and that opportunities are not the same regardless of gender, while fewer men feel the same way. On the contrary, more male students than female students recognize that both employees and the organization would benefit from an increased percentage of women in the workplace.
