Item Effects of Exposure to Noise on Mental Performance and Emotional Well-being of Students in a School in Kaduna, Nigeria(International Journal of Research and Scientific Innovation, 2025-05) Makun, Charles Yakubu; Lawal, Lateef AdemolaThe study investigated exposure to noise, mental performance and emotional wellbeing of students. Two simultaneous field experiments were performed each day for five days. At each experiment, 30 students performed mathematics and English language task in a quiet 38dBA classroom named, ExposureI(ExpI). Simultaneously, another 30 students performed the same mathematics and English language task in a noisy 75dBA classroom, named ExposureII (ExpII). After the tasks were performed, the students were asked to to rate their perceptions of annoyance and task dificulty with respect to the noise levels in the two expermental classrooms. Independent sample t-test and Welch’s test were used to analyse the data. Results from the data analysis showed that, in comparison to ExpI(38dBA),the performance of mental task related to mathematics was signficantly affected in ExpII (75dBA).There was no signfcant effect found in the mental performnce related to English language task between ExpI(38dBA) and ExpII(75dBA). Furthermore, the results from this study show that the students were signficantly annoyed in classroom with a noise level of 75dBA. Lastly, the results from this study suggests that mental tasks can be much difficult in noisy classrooms.The findings from this study highlight the critical need for architects and policy makers to prioritize acoustic considerations in school design and renovation.Item Impact of Biophilic Design Strategies on Wellbeing: A review(Journal of Biodiversity and Environmental Research, 2023-03) Omaga, Angela Ele-Ojo; Lawal, Lateef AdemolaIncreasing urbanization and technological development continue to have impact on people’s connection to nature and access to greenery and open spaces. Emerging from these concerns is a new set of design principles and practices where nature seems to play significant role, especially in the built environments. “Biophilic architecture.” is a design approach that suggests that humans have an innate connection with nature and could assist to create healthy living and workspace for human’s comfort and wellbeing. A significant amount of literature in environmental psychology field provides empirical evidence that nature benefits humans, and that landscape and built environments can be designed to link humans and nature. The paper is aimed at providing a narrative review on biophilic design and human health outcomes. The initial review found that elements such as natural daylight, ventilation, and living architecture (green roofs and walls) which are integrated on or within a building envelope could be useful in creating well designed buildings capable of improving users’ health and well-being. To achieve the status of a restorative-built environment, the study suggests that architects and designers need to shift focus on the value and the use of natural elements such as forest-like landscapes, natural water features, and natural light in their designs.Item Application of lean manufacturing tools and techniques for waste reduction in Nigerian bricks production process(In Engineering, Construction and Architectural Management Journal @ Emerald Publishing Limited, 2019) Aka, A.; Isah, A. D.; Eze, C. J.; Timileyin, O.Purpose – Non-value adding activities or wastes in the lean term have been the major challenge of the construction industry. Numerous studies have been conducted to investigate how such wastes can be reduced so as to improve the performance of the construction industry. However, the aspect of bricks production process (BPP) has not been extensively covered. Therefore, the purpose of this paper is to investigate the application of lean manufacturing concepts in BPP with a view to identifying the various wastes in the practice, the causes of these wastes and how such wastes can be reduced. Design/methodology/approach – Mixed methods research design was adopted by the researchers where literature review was first conducted to establish the fundamental theories and practice standards of lean manufacturing process. Thereafter, a phenomenological study was carried out in a Shelter Clay and Brick Factory located in Minna, Niger State, Nigeria. The data obtained in the phenomenological study were analyzed through content analysis. These data served as the basis for the validation survey that subsequently followed the phenomenological study. Findings – The findings in the study show that poor or inadequate supervision is the main factor responsible for wastes such as excessive drying of bricks, overheating of bricks and re-glazing of bricks in Nigerian BPP. Research limitations/implications – The study focused on the various wastes in Nigerian BPP. It also focused on the various lean tools/techniques that can be adopted to reduce the wastes. Aspects such as the percentage of the wastes and their cost implication on the factory were not covered during the study and could be further investigated by prospective researchers. Practical implications – The study provides knowledge on how lean thinking can be adopted to reduce wastes in BPP. Such knowledge may be beneficial to the present and prospective bricks producers. This implies that the proposed framework in the study allows producers of bricks to identify gaps in their implementation efforts, focus attention on areas that may require improvements, and access the benefits of lean approach in their factory products. The proposed framework may also be beneficial to the academics. Originality/value – This paper first gain originality in the study context to propose for a lean framework that can be adopted to reduce wastes in BPP. Furthermore, the paper has not been previously published and all the information obtained from other sources are duly referenced.Item Evaluation of Traditional Methods in the Maintenance of Mud Houses for Environmental Sustainability in Northern Nigeria(In Journal of Architecture and Construction-Sryahwa Publication, 2018) Eze, C. J.; Obaje, J. A.; Zubairu, S. N.Over the years, one of the major problems of traditional housing provision is poor maintenance habit/technique. Building maintenance is a subject that has to be considered seriously if buildings are to live up to their expected life span. Earth has been in use in all ancient cultures, every continent, in every age and is being recorded as one of the oldest and sustainable building materials on the planet known for over 9000 years but has the highest challenge of rapid deterioration. The research evaluated the problems caused as result of negligence in regular maintenance of mud houses in Nigeria and as well proffered various traditional methods to their maintenance which consequently improves the sustainability of the built environment. Qualitative research carried out through the administering of questionnaires, interviews and observations in some villages in the northern part of Nigeria has shown that buildings are left without proper maintenance or cared for minimally not following any particular routine. This scenario has resulted to diversified problems such as rapid depreciation or deterioration; low life span and eventually building collapses. The research concludes that there should be routine and regular maintenance of structures for apt environment sustainability.Item Geotechnical Assessment of Clay Deposits in Minna, North-Central Nigeria for Use as liners in Sanitary Landfill Design and Construction(American Journal of Environmental Protection, published by Science and Education Publishing, 2015) Amadi, A. N.; Okunlola, I. A.; Eze, C. J.; Jimoh, M. O.; Unuevho, C. I.; Abubakar, F.Abstract Sanitary landfills are waste disposal method that functions without creating nuisance to the environment. It confines waste to the available area, reduce waste to the minimum practical volume. The waste in a landfill reacts to release a cocktail of contaminants called leachate, which posses treat to the surrounding environment (soil and groundwater). Therefore, barrier soils are required for the lining of a landfill to prevent seepage of leachate into the surrounding groundwater and subsequent contamination of the groundwater system. Some clay in Minna was assessed using geotechnical techniques to determine its suitability as barrier soils. Five samples of clay were subjected to grain size analysis, atterberg limits, compaction tests and mineralogy test. From the grain size analysis and the atterberg limit, the soil is classified as a clayey material. The liquid limit ranged from 45.5%-61% with a mean value of 51.8% which is an indication of high plasticity and low hydraulic conductivity, the plastic limit ranged from 29.2%-35.8% with a mean value of 32.44% and its plasticity index ranged from 13.7%-25.2% with a mean value of 19.37% which implies that the clay can withstand volumetric shrinkage on drying and exhibit a low to medium swelling potential when wet. The compaction test reveal an optimum moisture content(OMC) ranging from 17.7% to 24% with a mean value of 19.94% and a maximum dry density (MDD) that varied from 1.59g/cm3 to 1.76g/cm3 with a mean value of 1.7g/cm3. This results of these geotechnical analysis suggests that the clay in the area meets the requirement for a barrier soil. The X-ray diffraction analysis reveals the presence of kaolinite dominated clay and mixed clay (kaolinite-illite). These minerals have the capability to attenuate and contain leachates from wastes. Hence, the studied clays are good barrier soils.Collection Collection Collection Collection
