A comparative study of different radial basis function interpolation algorithms in the reconstruction and path planning of γ radiation fields

Accurate reconstruction of radiation field and path planning are very important for the safety of operators in the process of dismantling nuclear facilities. Based on radial basis function (RBF) interpolation algorithm, this paper discussed the application of inverse multiquadric radial basis Function (IMRBF) interpolation method to the reconstruction of gamma radiation field, and proved the feasibility of reconstructing a radiation field with multiple γ sources. The average relative errors of IMRBF interpolation results were 4.28% and 8.76%, respectively, for the experimental scenarios with single and double gamma sources. After comparing the consistency between the simulated scene and the experimental scene, IMRBF method and Cubic Spline method were respectively used to reconstruct the gamma radiation field by Geant4 simulation data. The results showed that the interpolation accuracy of IMRBF method was superior to that of Cubic Spline method. Further, more RBF interpolation algorithms were used to reconstruct the multi-γ source radiation field, and then the Probabilistic Roadmap (PRM) algorithm was used to optimize the human walking path in the radiation field reconstructed by different interpolation methods. The optimal paths in radiation fields generated by multiple interpolation methods were compared. The results herein contribute to a comprehensive understanding of RBF interpolation methods in reconstructing γ radiation fields and their application in optimizing paths in radiation environments. The insights may provide valuable information for decision-making in radiation protection during the decommissioning of nuclear facilities.

PERFORMANCE ANALYSIS OF PEDESTRIAN PATHS IN THE COLONIAL HISTORICAL AREA OF KOTA LAMA CIREBON

Pedestrian path conditions are one of the factors that affect willingness to walk and play an important role in supporting historical tourism activities. This study analyzes the performance of pedestrian paths expressed by Pedestrian Level of Service (PLOS) in the colonial historical area of Kota Lama Cirebon. The method used in this study was to conduct a geometric survey of pedestrian paths, pedestrian flow surveys, and pedestrian travel time surveys in 10 segments scattered throughout the study area. The survey results were analyzed regarding the 1985 Highway Capacity Manual (HCM) and PLOS values generated based on available walking space. The study shows that in terms of walking space availability, most of the segments in the study area have a PLOS A score, which means they are performing well. In comparison, some segments have poor PLOS, such as Merdeka Street, Yos Sudarso Street, TJ Street, and Kebumen Street, due to the unavailability of sufficient walking paths to serve pedestrians or the presence of side obstacles that reduce the effective width of the pedestrian path. To overcome these problems, several things need to be done, such as: 1) issue a policy prohibiting selling on pedestrian paths to reduce side obstacles so that the effective width of the pedestrian path can increase; 2) widen the pedestrian path at least according to the applicable standards; and 3) provide pedestrian paths on segments that do not yet have pedestrian paths.

Does Texting While Walking Affect Gait's Plantar Pressure Parameters?

This study aims to examine the possible effects of mobile phone use on plantar pressure and spatiotemporal parameters during walking. Thirty volunteers (18 males and 12 females) participated in the study. A 10-m walking path was prepared, and a messaging connection was established. They were asked to write three posts without word or character mistakes and participants walked on the path walk as much as they wanted on the trail to make sure they were walking at their own pace. The gait's spatiotemporal parameters and plantar pressure parameters were recorded while walking. A paired samples t-test was used to determine whether there was a difference between normal walking and walking while texting. While walking and writing a message, cadence, speed, and step length decreased significantly (P < 0.05). In the plantar pressure parameters, the fore- and midfoot load and pressure were significantly increased (P < 0.05). Compared to normal walking, the forces on the forefoot and midfoot and the pressure per unit area increased in walking while texting. It is thought that the pace of walking slows down, and focus and attention shift to the front of the body.

Experimental study on fundamental frequency and human‐induced vibration characteristics of light steel foam concrete composite floor

SummaryIn order to study the dynamic characteristics and human‐induced vibration response of light steel foamed concrete composite floor (LCSF), the vibration characteristics of 4.2 m × 5 m LCSF model were tested under the condition of opposite side support, and the natural vibration frequency of LCSF was obtained. The orthogonal anisotropic elastic plate and the simulated beam element were used, respectively, to compute the natural vibration frequency of the LCSF, and the estimated findings were compared with those obtained from measurements. The discrepancy between the calculated results and the measured results of the approximate beam element using the natural vibration frequency calculation technique is around 13%, but the error for the plate element using the calculated results and the tested results is about 23%. To examine the floor's vibration response under the factors of step frequency, walking path, pedestrian density, and load distribution, the LCSF underwent a human‐induced vibration test. The test results show that the fundamental frequency of the LCSF specimen is about 11 Hz, which can meet the requirements of the specification. However, the vibration response of the LCSF specimen under different conditions of pedestrian load is significantly different. With the acceleration of step frequency and the increase and concentration of load, the floor's vibration response becomes more visible. In the route test, it is established that LCSF has the attribute of a unidirectional plate. The natural vibration frequency of similar floor slab can be calculated by the method of simulating the natural vibration frequency of beam element. The findings can serve as a guide for LCSF research and implementation.

Public support for proposed government policies to optimise the social benefits of autonomous vehicles

Governments will have a key role in establishing the policy environment needed to optimise the social outcomes associated with the evolution of autonomous vehicles (AVs). However, little is known about the extent to which the general public would support the diverse range of policies that could be implemented across human transport and product delivery AV applications. To address this deficit, the aim of the present study was to explore public support for a range of human transport and product delivery AV policies. In total, 1078 adult Australians completed an online survey that assessed transport-related attitudes and behaviours, including support for 11 AV policies pertaining to human transport and product delivery AV applications. Results suggest policies that ensure walking and cycling paths are prioritised for active transport (supported by 65%), limit the numbers of personal flying passenger AVs in the airspace (62%) and delivery bots on streets (64%), and ensure that those with mobility limitations have priority access to autonomous product deliveries (60%) are likely to be acceptable to the general community. To a somewhat lesser extent, limiting the operating hours for AV delivery services (51%) and banning the advertising of unhealthy foods and beverages on the surface areas of delivery AVs (50%) are also likely to be broadly accepted.

The Escarpão Plateau (South of Portugal)—a Study Case of Nested Geosites from the Aspiring Algarvensis Geopark

Located along the southern limit of the Algarvensis aspiring UNESCO Global Geopark (aUGGp), the Escarpão Plateau is a singular geomorphological structure sculpted by fluvial, karst, and tectonic processes. The plateau is deeply scarved by the Quarteira Rivulet, forming a valley that crosses the most complete Upper Jurassic sedimentary sequence of the Eastern Algarve (Southern Portugal). This sequence includes five geological formations representing different depths of carbonate ramp deposition from the Tethys Sea: Peral Formation, Jordana Formation, Cerro da Cabeça Formation, Escarpão Formation, and the upper Limestone Formation with Anchispirocyclina lusitanica (foraminifera), respectively from the oldest formation to the most recent at the top. Throughout the Quaternary Period, the karst processes shaped a landscape of sparse and poor soils, based on which successive generations adapted their subsistence agriculture and way of life. The geomorphology of the plateau and the rivulet valley, the sequence of the carbonated formations, and the diversity of sedimentary and paleontological records can be considered possible sites of diverse geological interest and with different scales that are embedded in each other, forming thus nested sites. To promote and preserve these sites, the Algarvensis aUGGp shaped an 8-km-long interpretative walking path, passing through 11 points of interest, including biosites and geosites. Their interpretative boards highlight not only the different spatial and temporal geological diversity but also its relationship with surrounding cultural and historical heritage. Finally, this work allowed the creation of new products for outreach and public awareness towards an effective geoconservation.

Exploiting Flat Namespace to Improve File System Metadata Performance on Ultra-Fast, Byte-Addressable NVMs

The conventional file system provides a hierarchical namespace by structuring it as a directory tree. Tree-based namespace structure leads to inefficient file path walk and expensive namespace tree traversal, underutilizing ultra-low access latency and superior sequential performance provided by non-volatile memories (NVMs). This article proposes FlatFS+, an NVM file system that features a flat namespace architecture while providing a compatible hierarchical namespace view. FlatFS+ incorporates three novel techniques: the direct file path walk model, range-optimized B r tree, and compressed index key design with scan and write dual optimization, to fully exploit flat namespace to improve file system metadata performance on ultra-fast, byte-addressable NVMs. Evaluation results demonstrate that FlatFS+ achieves significant performance improvements for metadata-intensive benchmarks and real-world applications compared to other file systems.

Real-walk modelling: deep learning model for user mobility in virtual reality

This paper presents a study on modelling user free walk mobility in virtual reality (VR) art exhibition. The main objective is to investigate and model users’ mobility sequences during interactions with artwork in VR. We employ a range of machine learning (ML) techniques to define scenes of interest in VR, capturing user mobility patterns. Our approach utilises a long short-term memory (LSTM) model to effectively model and predict users’ future movements in VR environments, particularly in scenarios where clear walking paths and directions are not provided to participants. The DL model demonstrates high accuracy in predicting user movements, enabling a better understanding of audience interactions with the artwork. It opens avenues for developing new VR applications, such as community-based navigation, virtual art guides, and enhanced virtual audience engagement. The results highlight the potential for improved user engagement and effective navigation within virtual environments.

Capabilities for Physical Activity in Older People: Development and Testing of a Measurement Tool

Based on Sen's capability approach, this study addresses the operationalization of capabilities for leading an active lifestyle. By assessing capabilities, processes of change can be mapped and the development of interventions to promote physical activity in different population groups, e. g., older adults, can be supported. However, no standardized German-language instrument for measuring physical activity-related capabilities is available to date. Building on an exploratory interview study (Sauter et al., 2019) that identified relevant physical activity-related capabilities in older adults, a standardized questionnaire with 41 items was designed. Two different question formulations were designed to query perceived capabilities for physical activity. The "think-aloud" method was conducted to validate the instrument. This involved recording all verbal comments made by participants while completing the questionnaire and conducting supplementary interviews for comprehensibility and applicability. The sample included 16 older adults (w=9, MW=66.3 years). Overall, respondents rated the instrument's usability and comprehensibility as good. For the questioning of perceived capabilities, the formulation "I have the possibility to..." was favored instead of "I perceive my personal opportunities as…". Difficulties in understanding and ambiguities were found in a few items. Thus, further changes were made to specify these questions with regard to unclear terms such as "walking paths". The questionnaire seems to be suitable to asses perceived capabilities for leading an active lifestyle in older adults. The final questionnaire is available in English and in German. Further research is needed to test the applicability of the instrument in other population groups and verify objectivity, reliability and validity.

Accuracy validation of a wearable IMU-based gait analysis in healthy female

ObjectiveThe aim of this study was to assess the accuracy and test-retest reliability of a wearable inertial measurement unit (IMU) system for gait analysis in healthy female compared to a gold-standard optoelectronic motion capture (OMC) system.MethodsIn our study, we collected data from 5 healthy young females. Participants were attached with markers from both the OMC system and the IMU system simultaneously. Data was collected when participants walked on a 7 m walking path. Each participant performed 50 repetitions of walking on the path. To ensure the collection of complete gait cycle data, a gait cycle was considered valid only if the participant passed through the center of the walking path at the same time that the OMC system detected a valid marker signal. As a result, 5 gait cycles that met the standards of the OMC system were included in the final analysis. The stride length, cadence, velocity, stance phase and swing phase of the spatio-temporal parameters were included in the analysis. A generalized linear mixture model was used to assess the repeatability of the two systems. The Wilcoxon rank-sum test for continuous variables was used to compare the mean differences between the two systems. For evaluating the reliability of the IMU system, we calculated the Intra-class Correlation Coefficient (ICC). Additionally, Bland-Altman plots were used to compare the levels of agreement between the two systems.ResultsThe measurements of Spatio-temporal parameters, including the stance phase (P = 0.78, 0.13, L-R), swing phase (P = 0.78, 0.13, L-R), velocity (P = 0.14, 0.13, L-R), cadence (P = 0.53, 0.22, L-R), stride length (P = 0.05, 0.19, L-R), by the IMU system and OMC system were similar. Which suggested that IMU and OMC systems could be used interchangeably for gait measurements. The intra-rater reliability showed an excellent correlation for the stance phase, swing phase, velocity and cadence (Intraclass Correlation Coefficient, ICC > 0.9) for both systems. However, the correlation of stride length was poor (ICC = 0.36, P = 0.34, L) to medium (ICC = 0.56, P = 0.22, R). Additionally, the measurements of IMU systems were repeatable.ConclusionsThe results of IMU system and OMC system shown good repeatability. Wearable IMU system could analyze gait data accurately. In particular, the measurement of stance phase, swing phase, velocity and cadence showed excellent reliability. IMU system provided an alternative measurement to OMC for gait analysis. However, the measurement of stride length by IMU needs further consideration.

Improving Walking Path Generation Through Biped Constraint in Indoor Navigation System for Visually Impaired Individuals.

This paper introduces a walking path generation method specifically developed for the Smart Cane, which is a RNA (Robotic Navigation Assistance Device) aimed at enhancing indoor navigation for visually impaired individuals. The proposed approach combines the utilization of a LIPM (Linear Inverse Pendulum Model) and LFPC (Linear Foot Placement Controller) motion primitives to generate walking paths specifically designed for visually impaired individuals. The primary objective is to generate paths that conform to human motion constraints, thereby guaranteeing an efficient and natural navigation experience. Integrating autonomous navigation framework, the Smart Cane facilitates safe and effective guidance for visually impaired participants in the indoor environments. Furthermore, comparative experiments have been conducted to validate the effectiveness of the proposed method, providing evidence of its capability to generate walking paths that conform to human motion constraints. The experiment results indicate that the proposed walking path generation method is a promising solution to enhance the navigation experience of visually impaired individuals.

Gender-Based Heat Map Images of Campus Walking Settings: A Reflection of Lived Experience.

Fear of crime can influence our view of and experience with the world around us. This can be problematic for individuals seeking physical activity, including from walk commuting. Prior work shows fear is especially evident among women, who report fear of rape and sexual abuse by men as a primary concern. We present the results of a cross-sectional survey (n = 571) where participants were shown images from college campus (n = 4 campuses) depicting different lighting (daytime, nighttime), and entrapment levels (high, low; i.e., able to easily escape if needed, with high entrapment being difficult and low being easy), and using the Qualtrics heat map tool, selected features that stood out to them most. Data were segregated by gender and analyzed to determine similarity of heat maps for the same base image. Heat map images were analyzed using canonical correlation (Rc) to determine the relationship between the two groups; dispersion testing to decipher spatial uniformity within the images; the Structural Similarity Index (SSIM) to characterize the nature of image patterns differences; and, the Breslow-Day Test to specify pattern locations within images. Several heat map images are also presented in the results. Overall, female and male participants appear to "see" different things when imagining walk-commuting (as seen by poor Rc values) and the nature of what they were looking at were different (as seen by poor SSIM values). Female participants tended to focus on areas outside the walking path, such as bushes and dark areas, whereas men's focus was on the path ahead [χ2(1) = 4.29, p = 0.04]. Furthermore, women were more likely to select areas outside the walking path during high entrapment settings [χ2(1) = 15.49, p < 0.001] and at nighttime [χ2(1) = 4.98, p = 0.02]. Our study demonstrates point-of-view differences in female-male walking space assessments. Viewing walking safety through the lens of lived experience could be productive for holistic community walking safety.

Gait variability and biomechanical distinctions in knee osteoarthritis: Insights from a 3D analysis in an adult elderly cohort

BackgroundThis study employs 3D gait analysis to investigate normal gait patterns in individuals afflicted with knee Osteoarthritis (OA). Focusing on the adult osteoarthritic population, the research aims to establish reference values for joint angles, temporospatial parameters, Gait Profile Score (GPS), and Movement Analysis Profile (MAP) collected concurrently along a standardized walking path. Furthermore, the study delves into potential variations linked to gender and OA severity, comparing gait parameters between male and female participants and among individuals with grade 3 and grade 4 OA. MethodThe study involved 34 adults with a mean age of 68.6 ± 5.75 years, all experiencing OA knees and awaiting Total Knee Arthroplasty (TKA). Utilizing Qualisys Motion capture system, 3D gait analysis was conducted. Data were processed through Visual 3D C-Motion Software. ResultsGait analysis revealed noteworthy differences between genders for various parameters, including stance time, GPS, MAP of the hip, and joint angle for the sagittal plane (ankle), coronal plane (knee), and transverse plane (hip and knee). Moreover, significant differences were observed between grade 3 and grade 4 OA knees in MAP and for the transverse plane joint angle (ankle). ConclusionThis gait analysis study sheds light on distinctive gait patterns in the adult osteoarthritic population. The identified variations in temporospatial parameters, joint angles, GPS, and MAP provide valuable reference values for individuals suffering from knee OA. The observed differences between genders and across different OA severity grades emphasize the need for personalized approaches in managing knee OA and planning interventions like TKA.

OUTDOOR ACTIVITY ENGAGEMENT PRIOR TO AND DURING THE COVID-19 PANDEMIC IN SENIOR LIVING COMMUNITIES

Abstract There is growing evidence regarding the benefits of spending time outdoors. However, it is less understood if the COVID-19 pandemic has deterred or increased older adults’ outdoor leisure activities when they reside in senior living communities. This study aimed to discover how the pandemic affects senior living community-residing older adults’ outdoor activities. Older adults 65 and older were recruited through ResearchMatch and university partnerships. A qualitative descriptive approach was taken with semi-structured individual interviews conducted over Microsoft Teams, telephone, or in-person. A conventional content analysis was employed. Interviews were conducted in 2021-2022 with 4 females and 3 males from suburban Pennsylvania. While there were indoor restrictions and regulations (e.g., mask wearing when around others), the outdoor environments were less regulated and routine outdoor activities continued during the pandemic. Facilitators to outdoor activities were: 1) senior living campus features (e.g., paved walking paths, outdoor recreational sport areas), 2) structured outdoor activities (e.g., bocce ball and golfing tournaments facilitated by staff), and 3) access to transportation (e.g., to drive or visit other locations). A barrier to outdoor activities was: needing assistance from staff to exit buildings due to decreased mobility. This study illuminates that amenities and structured activities at senior living facilities promoted mobility in outdoor activities for those who preferred going outside. Findings inform design features that encourage mobility and outdoor activities among older adults. Policy implications include supporting senior living communities with less resources for maintaining campuses and neighborhoods, which could contribute to promoting outdoor activities and health equity.

Thoughtful paths of Nature Park „Ogres Zilie kalni”

In many countries around the world, urbanization has led to a disconnection from nature within major cities and this has prompted increased research into the significance of nature in the daily lives of urban residents. In the wake of COVID-19 pandemic, people began to visit the walking trails en masse and the habit has continued even after the COVID-19 pandemic. This study, which was conducted in July of 2023 is a part of a broader research initiative aimed at enhancing recreational opportunities and optimizing the physical and wellness benefits provided by walking paths. The research is centered on the "Ogres Zilie kalni" nature park, which features recreational and activity trails. For a majority of residents, these walking paths and ski tracks are vital for recreation. The research's objective is to outline the planning principles for the nature park's trail network, drawing not only from landscape architecture but also from the field of environmental psychology. This holistic approach is expected to yield better recreational outcomes and subsequently improve human health. The primary goal of this study is to investigate how different types of nature walking trails impact human attention dynamics. Using Schulte's Tables, a psychological method, the study assessed how various stimuli in trail planning and route selection influence human attention. The research results do not offer a definitive answer regarding the influence of path type on attention dynamics. However, the findings indicate that attention dynamics tend to improve after the second or third measurement, typically occurring at 20-30 minute intervals. This aligns with the theory that 20 minutes is sufficient for attention reset. Attention dynamics then diminish towards the end of the walk due to physical exhaustion. It was hypothesized that adequate rest could lead to improved dynamics. In the modelling of the walking path network and route selection, cognitive factors such as the purpose of the walk, group participation, individual walks, social interactions, and the perception of the three-dimensional spatial environment serve as the foundation for designing the layout of walking paths. The study raises intriguing and complex research questions, further complicated by the diverse groups involved, including students, families, and the elderly. Social factors play a pivotal role in determining the optimal path for both fundamental research and practical applications. Understanding the mechanisms and information sources guiding decision-making in path selection should encompass not only psychological but also social aspects. This comprehensive approach will contribute to a better understanding of path planning for psychological wellness and the cultivation of emotionally positive behavioural patterns.

An ecological network for large carnivores as a key tool for protecting landscape connectivity in the Carpathians

ABSTRACT The main aim of our study was to delineate a coherent ecological network for large carnivores, using a unified methodology, which would be flexible and serve as a basis for nature and habitat connectivity protection across the Carpathians. We applied a comprehensive methodological approach based on habitat suitability modelling followed by connectivity modelling. For the habitat suitability modelling, we used a robust set of large carnivores occurrence data, which allowed us to build a solid model. From the model, we derived a layer of patches of suitable habitat of required quality and resistance surface to express landscape permeability. Both outputs were crucial for the connectivity modelling. We applied Random Walk and Least-Cost Path models and combined them to determine feasible connections between suitable habitats. With expert discussions and editing/improvement of modelled corridors, we developed a unique ecological network consisting of various components adapted to the heterogeneity of the Carpathian landscape.

Spatial Analysis of Risk Exposure of Urban Trees: A Case Study from Bologna (Italy)

In Europe, more than two-thirds of the population live in urban areas. The management of urban green areas and trees is becoming increasingly relevant involving different players and stakeholders, as well for keeping a focus on the Sustainable Development Goals. Society and policy makers are often unaware of the disservices that neglecting these areas can cause. Appropriate monitoring interventions can protect both citizens and trees themselves. The aim of the study was to assess the risk potential in urban trees in Bologna suburbs (Italy). For each tree in the city of Bologna, three target variables identifying the number and categories of streets, buildings, and walking and cycle paths near the tree were considered and used as covariates. A multiple regression model assessing the relationship between a dependent synthetic spatial variable (digital number, DN), proxy of the likelihood of tree failure, and the three independent covariates was estimated. Both the number of streets and walking and cycle paths in the area surrounding a tree are shown to be significantly associated with the DN value. The use of open data can assist in monitoring and maintaining urban green areas. The tool supports a virtuous circle between stakeholders in urban systems through sustainability and efficiency.

Motivations Behind Dog Walking in Older Adults: Insights From Guided Walks and Interviews.

For many older adults, physical activity declines with age, contributing to chronic disease and social isolation. Companionship from dogs can help mitigate isolation and promote physical activity. Outdoor environments aligned with the abilities of older adults can encourage walking habits and socialization. To understand how neighborhood features influence dog walking, we adapted a Photovoice approach and photographed 12 older adults walking their dog. Photographs were presented during in-person interviews to facilitate discussions about environmental features. Thematic coding revealed that interactions with nature were key. Participants valued choices in walking path type and conveniently placed dog waste stations. Opportunities to socialize with neighbors were also important. Safety from falling, other animals, and motorized traffic were concerns but were not enough to prevent walking. Our findings suggest that walking environments intended for older adults with dogs should include experiences with nature, diverse path designs, and dog-specific amenities.

AUTOMATIC COARSE CO-REGISTRATION OF POINT CLOUDS FROM DIVERSE SCAN GEOMETRIES: A TEST OF DETECTORS AND DESCRIPTORS

Abstract. Point clouds are collected nowadays from a plethora of sensors, some having higher accuracies and higher costs, some having lower accuracies but also lower costs. Not only there is a large choice for different sensors, but also these can be transported by different platforms, which can provide different scan geometries. In this work we test the extraction of four different keypoint detectors and three feature descriptors. We benchmark performance in terms of calculation time and we assess their performance in terms of accuracy in their ability in coarse automatic co-registration of two clouds that are collected with different sensors, platforms and scan geometries. One, which we define as having the higher accuracy, and thus will be used as reference, was surveyed via a UAV flight with a Riegl MiniVUX-3, the other on a bicycle with a Livox Horizon over a walking path with un-even ground.The novelty in this work consists in comparing several strategies for fast alignment of point clouds from very different surveying geometries, as the drone has a bird’s eye view and the bicycle a ground-based view. An added challenge is related to the lower cost of the bicycle sensor ensemble that, together with the rough terrain, reasonably results in lower accuracy of the survey. The main idea is to use range images to capture a simplified version of the geometry of the surveyed area and then find the best features to match keypoints. Results show that NARF features detected more keypoints and resulted in a faster co-registration procedure in this scenario whereas the accuracy of the co-registration is similar to all the combinations of keypoint detectors and features.

Batu Cermin Cave Labuan Bajo Development Strategy Based on Tourist Satisfaction Level

&lt;p&gt;&lt;em&gt;Tourist satisfaction is essential for the sustainability of tourism activities at tourist attractions. Batu Cermin Cave is one of the attractions in Labuan Bajo. Batu Cermin Cave underwent renovations in 2021 and reopened in 2022. Since then, no studies have shown tourist satisfaction with the services and facilities at Batu Cermin Cave. Therefore, this research aims to determine the satisfaction level and develop strategies based on the level of tourist satisfaction. This research uses a mixed-method approach with an explanatory sequential design. Quantitative data collection uses accidental random sampling techniques with survey questionnaires and qualitative data uses observation techniques. The data collected came from 124 respondents. Data was analyzed using importance-performance analysis. In the Keep Good Work Quadrant, there were nine attributes: the appearance of the tour guide, speed of service of the tour guide or staff in serving visitors, the readiness of the tour guide or staff in serving visitors, timeliness of service, reliability in service, politeness and friendliness, patience in serving, area parking, and walking paths in the Batu Cermin Cave Area. In the Low Priority Quadrant, there are four attributes: work equipment for staff and tour guides in serving visitors, trash cans, information boards, and places to eat and drink. The Overkill Quadrant is an attribute of providing exceptional services for tourists and the road to Batu Cermin Cave. In the Top Priority quadrant, namely, security when visiting Batu Cermin, toilets, and road signs to Batu Cermin Cave. The priority development strategy is based on the attributes of the Top Priority quadrant are 1) increasing visitors' sense of security when carrying out tourism activities at Batu Cermin Cave, and 2) Improving the quality of supporting facilities such as toilets and road signs to Batu Cermin Cave..&lt;strong&gt;&lt;/strong&gt;&lt;/em&gt;&lt;/p&gt;
