Exploring the Role of Smellscape in Enhancing Landscape Perception: A Case Study in the University History Museum

As the cultural importance of universities continues to grow, university museums have become key platforms for promoting university heritage and values. However, enhancing the visitor experience in these museums remains challenging. This study examines the effectiveness of smellscape in enhancing the visitor experience in university history museums, with a focus on how various scents impact visitors’ emotions. Using the Fuzhou University History Museum as a case study, the museum was divided into three distinct zones: the Historical Evolution Zone (HEZ), the Contemporary Development Zone (CDZ), and the Thematic Exhibition Zone (TEZ). Specific scents were selected for each area to evaluate their emotional impact, and data were gathered using electroencephalography (EEG) indicators, emotional questionnaires, and scent pleasure scales. The results indicated that calming scents like sandalwood and agarwood, used in the HEZ, convey a sense of historical depth but may also evoke negative emotions, whereas sage enhances positive feelings. In the CDZ, rosemary and mint significantly improve emotional states, while lemongrass exhibits weaker pleasantness and appears less suited for this area. In the TEZ, scents such as patchouli and orange blossom align well with future-oriented themes, demonstrating high levels of pleasantness and emotional value. Smellwalk interviews further validated the experimental results, revealing notable differences in the emotional impact of smellscape across different exhibit zones. A thoughtful selection of scents can enhance the cultural expression of spaces and effectively regulate visitors’ emotional experiences, strengthening the cultural resonance of museum environments. Future designers may consider incorporating olfactory elements into landscape design.

Randomized trial of early exercise rehabilitation and its effects on patients with acute coronary syndrome

To assess the psychological and physiological benefits of early exercise rehabilitation in patients with acute coronary syndrome (ACS). Among 559 ACS-diagnosed patients at Fuzhou University Affiliated Provincial Hospital from January to December 2021, 200 eligible participants were assigned to two groups. The control group received standard care, while the experimental group received early exercise rehabilitation in addition to standard care. The outcomes measured included changes in depression levels (PHQ-9), fasting blood glucose, and troponin I (TnI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels. Data were analyzed using SPSS, with t tests and chi-square tests for group comparisons. In comparison to the control group, the experimental group demonstrated significant improvements in PHQ-9 scores (P < 0.001) and lower fasting blood glucose levels before discharge (P = 0.046). Additionally, the experimental group had notably reduced TnI levels at 72 h after admission (P = 0.001), especially among non-diabetic NSTEMI patients over 60 years old, who showed decreased TnI levels at the 48-hour mark (P = 0.016). However, there were no significant differences in NT-ProBNP change values between the two groups (P > 0.05). Subgroup analysis revealed enhanced outcomes in the intervention group for ACS patients without smoking or drinking history and no heart failure (P = 0.025,P = 0.014,P = 0.018). Early exercise rehabilitation has notable benefits for ACS patients, including reduced depression, improved blood glucose control, and enhanced myocardial protection, especially in nondiabetic NSTEMI patients aged 60 and above.

Modeling and Causality Analysis of Human Sensorimotor Control System Based on NVAR Method

Article Modeling and Causality Analysis of Human Sensorimotor Control System Based on NVAR Method Jiyu Tan 1,2, Yurong Li 1,2,*, Qiurong Xie 3, and Xiaoling Wang 3 1 College of Electrical Engineering and Automation, Fuzhou University, Fuzhou 350108, China 2 Fujian Key Lab of Medical Instrument and Pharmaceutical Technology, Fuzhou University, Fuzhou 350116, China 3 College of Rehabilitation Medicine, Fujian University of Traditional Chinese Medicine, Fuzhou 350122, China * Correspondence: liyurong@fzu.edu.cn Received: 2 September 2023 Accepted: 19 October 2023 Published: 21 December 2023 Abstract: Neuromuscular disorders (such as stroke and spinal cord injuries) can lead to nerve damage that profoundly affects a patient's ability to control limb movements. Analyzing and modeling the human sensorimotor control system can establish a neurophysiological foundation for both fundamental research and clinical rehabilitation assessment. Electroencephalogram (EEG) signals provide insights into how the cerebral cortex regulates limb movements, while electromyogram (EMG) signals reveal how muscles respond to motor commands. Utilizing these signals, cortical-muscular models can be developed to facilitate the quantification and assessment of the human sensorimotor control system. This study proposes a method based on the nonlinear vector autoregression model and coiflets wavelet packet decomposition to perform multivariate time-frequency Granger causality analysis. The objective of this analysis is to compute the cortical-muscular causality matrix during elbow extension in stroke patients and construct a cortical-muscular causal network. The result reveals a frequency-dependent directed information flow pattern in the cortical-muscle causality matrix during elbow extension. Specifically, the GC values of EEG→EMG (down) and EMG→EEG (up) in the alpha and beta bands are significantly higher than those in the gamma band. The cortical-muscular causal network of stroke patients does not have small-world properties. The result indicates that the proposed method is able to characterize functional connections of brain myoelectric synchronization in different frequency bands within the time-frequency domain. It also uncovers the causal association that inherently exists in the human sensorimotor control system, providing a theoretical basis for further evaluation and quantification of the human sensorimotor control system.

Analysis of the Impact of Layout Mode on the Wind Environment of Dormitories in Coastal Universities in Southern Fujian Province

The building wind environment in coastal areas is highly complex and variable, particularly during winter when strong winds prevail. Understanding the influence of winter winds on human comfort and addressing health issues caused by wind noise in human settlements are very valuable research topics. This study focuses on developing strategies to optimize the wind environment in dormitory buildings located in the southern coastal area, where prolonged periods of strong winds have a significant impact. Specifically, we investigated the current wind in the teacher–student dormitory at Jinjiang Campus of Fuzhou University through questionnaire surveys and field measurements. Additionally, computational fluid dynamics (CFD) simulations were employed to evaluate different dormitory layouts. The research results indicate that it is preferable to position the dormitory areas downwind of large-scale buildings, adopt a staggered layout instead of a regular determinant layout to mitigate the narrow tube effect, avoid designing large-scale squares in the center of the dormitory areas, and enclose the dormitory groups with low-level corridors. These findings provide valuable guidance for the optimizing of winter windproof designs of university buildings located in the same climatic zone along the southeast coast.

The role of overstrength in welded joints for rebar substitution in damaged RC columns

Rehabilitating corroded or seismically damaged reinforced concrete (RC) bridge columns often involves replacing the longitudinal steel rebar. Welded joints offer a practical and efficient in-situ solution for connecting new rebar segments to existing undamaged rebar, even with irregularities in the steel reinforcement. However, traditional approaches to rebar joint welding have paid little attention to the overstrength of the welding seam, which can result in a brittle response. Properly designing such joints should aim for a ductile rebar failure. However, in-situ rehabilitation solutions often require reducing the seam length to save time and material costs and, not secondarily, avoiding the plastic hinge formation in the rehabilitated column. Therefore, providing the seam with adequate overstrength is crucial to achieving a ductile failure of the welded joint. This study presents an experimental investigation into the most effective methods for connecting existing and new rebar segments through welding, addressing on-site welding challenges such as limited operational space and weld orientation. Over 100 tensile tests have been conducted at Fuzhou University’s laboratory in China to understand the response of nine welded joints. Among indirect butt joints, the study identifies two performance groups based on the ductile failure rate as the welding seams reduce. The symmetry of the joint and the presence of additional direct butt welding also in asymmetric joints can significantly improve the joint performance, determining a ductile failure with minimal welding lengths. In a second step, following a probabilistic approach, the study assesses the overstrength of indirect butt joints as a function of seam length for the two identified performance groups. Empirical failure probabilities of the rebar and the seam are estimated to fit probability density functions representative of the tensile strength of the rebar and the seam. Based on a target reliability class, the overstrength factors are estimated.

The Sense of Safety and Active Leisure in Gated Enclaves: Evidence from Fuzhou University Campus

Scientific interest in how residential patterns affect both people’s subjective sense of safety and their behavior is increasing. The surge of gated communities in the world has changed the way we live to a great extent. Research on the gated development trend in postmodern cities is still limited; therefore, the purpose of this study was to analyze the relationship between residents’ attitudes toward gated enclaves and their sense of safety. At the same time, the relationship between a sense of security and active leisure behavior was also investigated. Using data collected from 350 college students in Fuzhou University Town, this study introduces a conceptual model to test the relationship between closed enclaves, campus security, and active leisure behavior while controlling population and community characteristics. The results of structural equation model analysis show that gated enclaves positively correlate with campus safety and positively correlate with active leisure behavior, and a safe campus positively correlates with active leisure behavior. The results of this study focus on the importance of gated enclaves as a living environment, and the discovery of functional characteristics of gated enclaves supports future interventions. In other words, when promoting active leisure behavior and increasing the sense of safety in the neighborhood environment, attention must be paid to the characteristics of these gated enclaves. In addition, the simultaneous measurement of these structures provides a dynamic observation of the existing environment, as well as information for future research and construction. Decision makers and urban planners can use these results to promote interaction and healthy behavior in the community under the multi-angle development of the existing access control, thereby improving residents’ sense of security, and increasing leisure participation.

Systematic mapping of DNAzymes research from 1995 to 2019

DNAzymes (catalytic DNA) have gained significant diagnostic and therapeutic applications with increasing research output over the years. Functional oligonucleotides are used as molecular recognition elements within biosensors for detection of analytes and viral infections such as SARS-CoV-2. DNAzymes are also applied for silencing and regulating cancer specific genes. However, there has not been any report on systematic analysis to track research status, reveal hotspots, and map knowledge in this field. Therefore, in the present study, research articles on DNAzymes from 1995 to 2019 were extracted from Web of Science (SCI-Expanded) after which, 1037 articles were imported into Rstudio (version 3.6.2) and analysed accordingly. The highest number of articles was published in 2019 (n = 138), while the least was in 1995 (n = 1). The articles were published across 216 journals by 2344 authors with 2337 multi-author and 7 single authors.
