Literature suggests post-secondary students felt disengaged and socially isolated while learning virtually, especially during the COVID-19 pandemic. Here we explored whether a sense of belonging is differentially achieved in an inquiry-based course between two different delivery formats: virtual and blended (combination of virtual and in-person). Our primary measurement instrument was a modified version of the 26-item Sense of Belonging-Revised Scale, which we distributed to all first-year health sciences students enrolled in an Inquiry course at [institution name removed for blinding purposes] University during the 2021-2022 school year. Data analyses revealed no statistically significant difference between the two groups across the four subscales of the Sense of Belonging-Revised Scale: perceived peer support, perceived classroom comfort, perceived isolation, and perceived faculty support. As promoting community is a core skill in our Inquiry course, this may have reduced the perceived difference between the two groups. Future directions include exploring facilitators’ perceptions and experiences across course delivery formats.

Designing a Resilient Building Maintenance Program: Integrating Preventive and Predictive Maintenance at the U.S. Navy
Authors: Pluméy Nathan , Kim Amy 
Published: April 2024

ABSTRACT
Building equipment failure can have drastic effects on a company's operations and budget. This paper presents two types of maintenance approaches that if done effectively, can prevent or significantly reduce the failure of building equipment assets. The first is traditional time-based preventive maintenance (PM), which conducts prefailure inspections and tasks in a cyclic time-based approach. The second, is predictive maintenance (PdM), which conducts maintenance functions based on the condition of the equipment found through continuous or cyclic measurements and analysis during machine operation.
The purpose of investigating these maintenance approaches is to determine whether we can improve on the U.S. Navy's (Navy) existing facility maintenance program, helping to reduce overall costs while improving sustainability, equipment resiliency, and efficiency. By presenting each maintenance program and leveraging today's technologies we show that these advancements in technology can directly improve the Navy's operational mission and warfighter readiness.
Research was conducted through the following methods: interviews, books, third party reports, journal articles, industry websites and articles that focus on equipment maintenance. The Navy, the National Aeronautics and Space Administration (NASA), and the University of Washington provided case studies, existing facility/utility maintenance data, and budget information used in this research. The results show that PdM approaches using advanced analytics are more effective in diagnosing equipment, prescribing equipment problems, and predicting equipment failure. It will also show that when a PdM model is used, building tenants have less operational impacts as equipment operates longer with less downtime between maintenance events. By changing to a PdM program, facility managers and owners can improve asset efficiency and resilience, directly improving environmental sustainability and lowering overall longterm costs. It highlights the significant capital costs of a fully online PdM program and the benefits of using a hybrid model of PM and PdM.
This research concludes with an overview of how building maintenance is currently being conducted on Navy bases by Naval Facilities Engineering Systems Command (NAVFAC), and how they are transitioning to a more sustainable maintenance program leveraging existing advanced metering infrastructure (AMI), building control systems (BCS), and utility control systems (UCS) with Smart Grid (SG), OSI Pi, and advanced analytics. In addition, major gaps in this transition are identified, and solutions are proposed to optimize these building system investments.
Factors Influencing Energy-Efficiency Retrofits in Commercial and Institutional Buildings: A Systematic Literature Review
Authors: Kim Amy A. , Medal Lysandra 
Published: April 2024

ABSTRACT
Renovating existing buildings to render them more energy efficient is critical. However, current energy-efficiency efforts in the building sector remain insufficient. Despite the growing literature related to energy efficiency in buildings, context-driven reasons for stakeholders to undertake energy-efficiency retrofits remain less understood. The researchers conducted a systematic literature review to synthesize and consolidate the results of studies worldwide from 2009 to 2020, examining factors and associated contexts that influence building stakeholders’ decisions to implement energy-efficiency retrofits. The review involved searching databases and topic-specific journals using multiple keywords and synonyms for energy-efficiency retrofits and decision-making. The initial search yielded 25,093 articles, and 134 were further assessed for inclusion and exclusion. Forty-two of those articles met the criteria for inclusion and were examined to evaluate the factors and context associated with the decisions related to energy-efficiency retrofits. Recent relevant research was analyzed, considering methodologies, regions, economic development, building types, participant characteristics, and study size. Based on the extensive review of the literature, this study identified 30 factors that can be categorized under seven decision criteria involved in determining retrofits: economic feasibility, team process, technical practicality, institutional characteristic, governmental policy, occupant impact, and environmental impact. The main factors that influenced energy retrofit decisions included life cycle cost, coordination and collaboration, system compatibility, internal value, government commitment, satisfaction and well-being, and eco-friendly installation. Variations regarding factors influencing stakeholders’ perceptions among different regions and building types were also examined. The study found that risk management, technology readiness, and standards and regulations were more significant in countries with developing economies. Conversely, system compatibility, reputation, and political influence were more important in developed economies. The findings from this study provide insights into future research that may guide the development of more context-appropriate strategies that drive stakeholders to implement energy-efficiency retrofits in their buildings.
Senior Management Succession Challenges for U.S. Healthcare Facility Operations
Authors: Call Steven , Smithwick Jake 
Published: April 2024

ABSTRACT

Purpose
The purpose of this research was to better understand current state of mid- and senior-level healthcare facility managers to explore potential roadblocks to FM succession related to demographics, backgrounds, and perceptions in supporting future research prioritization for healthcare facility executive leadership development.

Methodology
A survey was designed to collect information on facility managers’ gender, race, age, job level, employer industry, retirement timeframe, educational attainment, and perceptions of their employers’ recruiting and succession planning. The survey was sent electronically in February 2021 to more than 12,400 FM professionals with a 29% response rate. Only information from U.S. respondents working in healthcare facility operations was used in this study.

Findings
The healthcare industry is struggling to attract and retain senior-level facility managers. The difficulty in finding qualified facility managers to fill senior-level positions does not appear to be related to a lack of interested candidates or pay. Factors impeding recurring facility workforce development and succession to senior healthcare FM roles may be related to low succession planning adoption by healthcare organizations, an aged facility workforce, and limited undergraduate education achievement from traditional candidates.

Originality
Healthcare organizations may prioritize these factors in addressing ongoing FM workforce attrition and development challenges to ensure a sustainable pipeline of qualified facility managers prepared to successfully navigate the unique expectations of leading the healthcare built environment.

Las hojas de stevia (Stevia rebaudiana Bertoni) son consideradas edulcorantes naturales, bajos en calorías e inocuos. Por su parte, los tallos de stevia han sido menos estudiados y se consideran subproductos agroindustriales, aunque representan una buena fuente de fibra con propiedades tecnofuncionales que podría utilizarse como ingrediente alimentario. El objetivo del presente trabajo fue evaluar las propiedades químicas y tecnofuncionales de los tallos de stevia como potencial ingrediente de alimentos funcionales. Los tallos fueron obtenidos de plantaciones de stevia en Yucatán – México, y se les determinó la composición química proximal y su perfil tecnofuncional considerando la retención de agua y de aceite, la absorción y adsorción de agua y la absorción de moléculas orgánicas. Las determinaciones analíticas fueron realizadas por triplicado y se utilizó un análisis de varianza de una vía para el análisis estadístico de los datos obtenidos. Estos presentaron un alto contenido de carbohidratos (54,84 %), fibra cruda (32,33 %), cenizas (6,99 %) y proteína (4,46 %). Los tallos retuvieron cinco veces su peso en agua y en aceite (5,57 y 5,00 g/g), respectivamente. La capacidad de absorción de moléculas orgánicas fue de 2,09 g/g, la absorción de agua iguala a 4,49 g/g y la adsorción de agua de 0,29 g/g. Los tallos como subproducto agrícola de la cosecha de hojas de stevia son una alternativa funcional para usar en la elaboración de alimentos con potenciales efectos fisiológicos.

Published: April 2024

Liquid fertilizer applicator based on Variable Rate Application (VRA) is a technology that is used to fertilize in a controlled and precise manner. This study aims to improve the effectiveness and efficiency of the fertilization process of chili plants. The development carried out is esp32 cam which serves to detect chili plants that lack elements. The method used is input of the nutritional needs of chili plants, spray doses of each plant, and a microcontroller to control applicator components such as sprayer pumps, selenoid valve, and esp32 cam. In this liquid fertilizer applicator there are 2 pipes, each pipe has 4 nozzles. The results of laboratory tests show that the discharge of liquid fertilizer sprayed follows the input results of the nutritional needs of chili plants. The discharge released on the PWM sprayer motor varies from 40 to 100% resulting in very different discharge variations in each PWM spray. The efficiency of this VRA-based liquid fertilizer applicator reaches 87% or an increase of about 14.7% from the applicator before development. Regression analysis of dimmer level to spraying discharge showed a function y = 6.3016x + 18.937 with an R 2 of 0.9921. While the regression analysis of the dimmer level of the applicator speed obtained the function y = 94.075x + 20.203 with an R2 of 0.9936. Keywords: Chili plants, Liquid, Fertilizer, Applicator, VRA.

Abstract
A 90° hybrid coupler operating at a central frequency of 5.40 GHz is introduced, offering high-performance characteristics with compact dimensions of 616.65 mm&sup2; (33.3 mm × 18.5 mm). These features are achieved while maintaining a design that makes it easy to produce. The unique aspect of this microstrip FR4 substrate-based design is the consistent S-parameters, which remain steady despite changes in structural dimensions, thereby making it adaptable to fabrication variations. The reported S-parameters measured in 5.4 GHz are as follows: |S11|= –29.46 dB, |S21|= –4.11 dB, |S31|= –3.96 dB, and |S41|= –21.23 dB. This hybrid coupler operates over a bandwidth of 0.8 GHz (16%), demonstrating remarkable performance within this spectrum. In addition to its design, the coupler exhibits robust resilience against changes in substrate parameters and structural dimensions, ensuring reliability during the fabrication process. Following thorough simulation studies, a physical prototype of the coupler was constructed and subjected to laboratory measurements. The experimental results align closely with the simulation data, validating the accuracy and predictability of the design. In comparison with other studies and designs documented in the literature, this compact, high-performance 90° hybrid coupler exhibits clear advantages in terms of size, isolation, phase deviation, and structural complexity. Therefore, the benefits and applicability of this presented structure in the context of microwave circuits and systems are underscored. It’s noteworthy to mention that the central frequency of 5.4 GHz falls within the sub-6 GHz 5G band range.

Published: April 2024

Abstract
The paper presents the performance enhancement of band-pass filter-based M-class phasor estimation. The performance of the M-class phasor estimation using a band-pass FIR filter is enhanced with a magnitude correction factor for the off-nominal frequency range. The band-pass filter is implemented for the phasor estimation with various window functions Tukey, Rife Vincent class-I order-2 (RV2), Hamming, Hanning, Blackman, and Flat-top (FT) and its performance are evaluated under the steady and dynamic state tests prescribed by the standard. A rigorous performance analysis of enhanced phasor estimation using band-pass FIR filter with various window functions is presented with the accuracy indices of total vector error (TVE), frequency error (FE), and rate of change of frequency error (RFE). The result analysis reveals that the performance enhanced phasor estimation using band-pass FIR filter offers significantly less error than reported work at the low sampling rate. The design and performance analysis of the phasor estimation using the band-pass FIR filter is performed in the MATLAB platform.
On Local Governments Ombudsman in Turkey: A Comparative Analysis with the Local Governments Ombudsman in Uk and Italy
Authors: Doğan Kadir Caner , Parlak Bekir 
Published: April 2024

Objective: The Ombudsman is essentially an independent, national-level institution that operates in response to complaints from citizens in order to steer public administrations away from bad administrative practices and behavior. However, it is impossible for an ombudsman with such a broad mandate at the national level to deal with all administrative complaints within the state. Therefore, in order to get more efficiency from the national Ombudsman, it has been divided into different sub-types.

Theoretical Framework: One of these is the Ombudsman for local governmentrs, which deals only with complaints from local administrations. Although there is a national ombudsman in Turkey, there is no ombudsman specialized in local governments.

Method: This study aims to make some suggestions for the Ombudsman for local governments envisaged to be established in Turkey in the future by analyzing the local governments ombudsman offices in the UK and Italy in terms of their structural-institutional and functional aspects. In this context, the study, with a comparative approach, provides suggestions for the basic aspects, qualities and characteristics of the Turkish local government ombudsman and, thus, for its structural-institutional and functional aspects. The method of the research is literature review.

Results and Discussion: According to the results of this research; Establishing an ombudsman for local governments in Turkey by law, cooperating with other ombudsmen in the vicinity, examining and correcting the mismanagement and bad behavior of local governments upon public demand, ensuring easy and cheap access, fulfilling their duties, and quickly and systematically addressing the faults of local governments. Warning, making suggestions, preparing reports and then reporting the situation to local decision-making boards and the public will be effective in providing public services more effectively and efficiently and strengthening local democracy.

Originality/value: In the study, original suggestions are made for local government ombudsman in Turkey, based on the examples of UK and Italy.
