This study explores the digital transformation and public value created through the target city’s smart city Mobile Payment APP and digital city token system within the context of sustainable governance in Taiwan. Adopting a convergent mixed-methods research design, this research integrates quantitative Importance–Performance Analysis (IPA) surveys of 632 users with qualitative in-depth semi-structured interviews involving eight key stakeholders (namely, government officials, system developers, affiliated merchants, and citizen representatives). This methodology assesses service quality, user satisfaction, and cross-sector collaboration effects. The findings reveal that the mobile payment platform significantly enhances digital service delivery; fosters user engagement; and supports sustainable urban development goals, particularly net-zero carbon emissions. However, the IPA results highlight critical service gaps in the “Priority Improvement Zone,” specifically regarding the insufficient number of affiliated merchants and inconvenient information search functions. Qualitative findings attribute these gaps to cross-departmental administrative barriers and security-focused design trade-offs. This study contributes empirical evidence on the integration of financial technology and public service innovation as a means to advance smart governance and sustainable urban ecosystems. The results provide actionable insights for policymakers, city planners, and service designers focused on promoting digital public services that facilitate economic vitality, environmental sustainability, and collaborative governance.

Background and Aims: Little is known about metabolic dysfunction-associated steatotic liver disease (MASLD) as a risk factor for hepatocellular carcinoma (HCC) in non-cirrhotic (HCC-NC) patients. In-house developed mouse models with defective lipid-metabolizing enzyme long-chain 3-hydroxy acyl-CoA dehydrogenase (LCHAD), coded by hydroxyacyl-CoA dehydrogenase trifunctional multienzyme complex subunit alpha (HADHA) gene, result in MASLD (steatosis) without cirrhosis leading to HCC-NC. The aims of the current investigations are to assess molecular markers and the associated molecular events that may lead to HCC-NC. Methods: cDNA array study of HCC patients was conducted to assess the expression of HADHA transcripts. Differentially expressed proteins identified between wild-type (WT) and heterozygous mice with no cancer (HT) from a previous study were subjected to Ingenuity Pathway Analysis (IPA). Western blotting was performed to assess the expression of proteins. Results: IPA of the differentially expressed proteins between WT and HT mice results in two biological networks (network 1 and network 2), which pointed to an important role of p53 in HCC-NC. Validation of the levels of MDM2 and p53 also highlights the role of MDM2-p53 axis in HCC-NC. All the focus molecules in network 1 and network 2 are either presented as tumor suppressor/promoter of carcinogenesis or serum markers for early HCC diagnosis. The hepatotoxicity report from IPA further identified four functional groups including liver steatosis, glutathione depletion, hepatocellular carcinoma, and liver hyperplasia/hyperproliferation. Conclusions: This study suggests that impaired fatty oxidation may play a role in the development of HCC associated with steatosis but without cirrhosis (HCC-NC). Defective LCHAD is a novel etiology for HCC. Full article

The global construction industry is facing pressure to reduce environmental impact by improving energy efficiency amid rising energy demands and growing concerns about climate change. Consequently, sustainable building practices, like the Passive House (PH) design, prioritize minimizing building energy demand. In Saudi Arabia, where cooling loads dominate electricity use, implementing PH could significantly lower energy demand. However, research on PH challenges in the Saudi climate is limited, which highlights the importance of investigating the barriers and potential solutions for PH adoption in this context. This study investigates barriers to PH adoption and proposes context-specific solutions for Saudi Arabia. A mixed-methods approach, including a literature review and structured questionnaires among construction professionals, was used. Thematic analysis and importance–performance analysis (IPA) helped prioritize barriers and identify strategies. By combining evidence from the literature and practitioner surveys, this study uniquely prioritizes PH adoption barriers and proposes tailored solutions for Saudi Arabia’s hot climate. The results showed that the most critical barriers include a lack of supportive building codes, the absence of government incentives, low awareness, contractor resistance, and limited material availability. At the same time, key strategies were identified, such as revising building regulations, offering tax incentives, and adapting PH design with improved shading and HVAC systems. Overall, these findings indicate that removing the identified barriers and implementing the suggested strategies can reduce energy demand and demonstrate the feasibility of PH in Saudi Arabia’s hot climate, thereby supporting the Kingdom’s broader sustainability goals.

Traditional villages are critical to preserving cultural heritage and promoting sustainable rural development. This study evaluates the development potential of 47 traditional villages in Jilin Province from the perspectives of spatial planning, architectural conservation, and rural real estate revitalization. A Development Potential Assessment (DPA) framework is constructed based on five dimensions: geographical position, cultural resources, socio-economic factors, natural ecology, and living environment. The AHP-entropy weighting method is applied to ensure objectivity in scoring, while kernel density analysis and coefficient of variation techniques identify spatial patterns and internal disparities. To further inform strategic planning and targeted investment, an Importance–Performance Analysis (IPA) model is introduced, aligning resource advantages with development performance. Key findings include the following: (1) significant spatial heterogeneity, with higher potential concentrated in the southeast and lower levels in the northwest; (2) cultural and socio-economic dimensions are the most influential factors in differentiating development types; and (3) a subset of villages shows a disconnect between resource endowment and realized potential, indicating the need for tailored design interventions and investment strategies. This research offers a visual and data-driven basis for differentiated revitalization strategies, integrating urban science methods, architectural thinking, and real estate development logic. It supports refined policy implementation, spatial design decisions, and the activation of underutilized rural assets through context-sensitive planning. Full article

The increasing development of coal mining subsidence wetland parks has led to a growing focus on assessing their ecological, economic, and social benefits following ecological restoration. This study establishes an assessment framework for the social landscape performance of coal mining subsidence wetland parks based on the landscape performance series (LPS), cultural ecosystem services (CES), and the unique characteristics of coal mining subsidence wetland parks. The framework integrates expert opinions and field research to select indicators, resulting in a comprehensive evaluation system comprising 28 indicators across five dimensions. Taking the Pan’an Lake National Wetland Park (PLNWP) in Xuzhou, China, as an example, we conducted empirical research by collecting data through questionnaires and on-site interviews. Using the fuzzy comprehensive evaluation method, the social landscape performance score of PLNWP was 3.511, which is rated as “good.” The importance–performance analysis (IPA) was applied to identify differences in the perceptions of visitors and local residents regarding the social landscape performance of the PLNWP. Local residents highlighted the need to enhance the amenity of waterside spaces, while visitors focused on the accessibility. Finally, based on the performance score and the perceptions from different stakeholders, optimization strategies were proposed in four aspects: enhancing waterside space amenity, optimizing accessibility, improving educational facilities, and addressing diverse user needs. This study could provide a feasible assessment framework and optimization guidance for other coal mining subsidence wetland parks. Full article

With continuous urbanization, cities are facing numerous challenges. In addition, the construction and effective management of urban green spaces have become essential for the sustainable development of healthy cities. In previous studies, algorithms were developed to select appropriate locations for parks with distinctive green patches. Although the suitability of urban parks has been discussed from various perspectives, the location and land use around parks have been rarely considered. Therefore, the benefits and importance of parks across various land uses were assessed in this study. Based on the assessment results, improvement strategies for future park planning and development were proposed. By highlighting and integrating the benefits of different parks, urban green spaces can be expanded to deliver diverse benefits and contribute to healthy and sustainable development. We compiled 35 items in four major types of park benefits from a literature review. Using the Delphi method, 24 important benefits of parks were identified. An importance–performance analysis (IPA) was then conducted to create matrix diagrams for parks in different land use zones to understand the key benefits and identify areas that require priority improvement. The IPA results indicated that parks in residential and industrial areas need to improve ecological benefits and environmental functions for sustainable development. Parks in districts have greening and visual appeal but need improvement in environmental education. There are excessive facilities for passive activities in parks, suggesting a need for resource optimization. The results of this study help urban planners find region-specific design solutions for different land uses and effectively manage and optimize resource allocation. Full article

This study investigates the job competencies and training needs of net-zero sustainability management personnel in Taiwan, in response to increasing climate change and ESG-related challenges. Using the Importance-Performance Analysis (IPA) method, the research surveyed 26 experts and 395 corporate sustainability professionals based on official competency standards issued by Taiwan’s Workforce Development Agency (WDA) and the Industrial Development Administration (IDA). The results indicate that training is most urgently needed in seven knowledge competencies (e.g., sustainable development concepts, GHG inventory reporting, and international sustainability standards), eight skill competencies (e.g., project planning, cross-departmental communication, cost budgeting, and benefit analysis), and one key attitude competency—proactiveness. The study also identifies discrepancies between expert evaluations and personnel self-assessments. While limited by its reliance on self-reported data, cross-sectional design, and constraints in identifying all net-zero engaged organizations, this study contributes original insights into sector-specific training priorities. The findings provide a guide for organizations to develop targeted, competency-based training programs that can enhance sustainability performance and support Taiwan’s transition toward net-zero emissions.

Agricultural systems face increasing challenges due to climate change, necessitating effective adaptation and mitigation strategies. This study investigates smallholder farmers’ perceptions of the efficacy of these strategies in The Gambia, employing a mixed-method approach that includes a perception index (PI), effectiveness score (ES), importance–performance analysis (IPA), and statistical analysis. A structured survey was conducted among 420 smallholder farmers across three agricultural regions. Farmers rated adaptation and mitigation strategies using a Likert scale, and a PI was developed to quantify their responses. The index was 0.66, indicating a moderate level of perceived effectiveness. Additionally, ES was calculated to assess the performance of various strategies, while IPA categorized strategies based on their adoption and perceived impact. Chi-square tests and factor analysis were applied to explore differences in perceptions. The findings reveal that strategies such as crop diversification, pesticide application, irrigation, and the use of inorganic fertilizers are widely adopted and perceived as effective. The IPA matrix identified key strategies needing improvement, particularly those with high importance but low performance. Barriers to adoption include limited financial resources (77%), lack of government support (64%), and insufficient knowledge (52%), with no significant gender-based differences in perceptions. This study underscores the need for policy interventions that integrate farmers’ perceptions to enhance climate resilience. Targeted investments in adaptive technologies, financial support, and knowledge-sharing platforms can improve adoption and effectiveness. This research provides valuable insights into the interplay between farmer perceptions, adaptation strategies, and agricultural sustainability in The Gambia. Full article

This study aims to explore the pivotal role of rural tourism in addressing the “three rural issues” and promoting rural revitalization. This study selects two representative villages in China that adopt different models of tourism development: Shibadong Village in Huayuan County, Hunan Province, which adopts a government-led model, and Yuanjia Village in Lixian County, Shaanxi Province, which follows a community-led model. This study evaluates the impact of rural tourism on rural revitalization using the Entropy-TOPSIS method. Utilizing the IPA (Importance–Performance Analysis) method and an independent samples t-test, a comparative analysis of the two models was conducted to reveal the differences in the effects of rural tourism in promoting rural revitalization between the different models. This study reveals that rural tourism positively impacts the revitalization of rural industries, ecology, culture, talent, and organization. However, the effects of tourism in promoting rural revitalization vary across different tourism development models. This study further suggests that the “multiple interlocking model” may be the future trend of rural tourism development as it can better integrate the resources of the government, communities, and enterprises to achieve more effective rural revitalization. This study deepens the theoretical link between rural tourism and rural revitalization, providing concrete guidance for practice, especially in strategies that drive comprehensive rural revitalization through tourism. Future research should further explore the corporate-led model and the multiple interlocking model and track the evolution of tourism development models through longitudinal comparisons to adapt to the changing needs of rural development.

Urban parks are pivotal in the sustainable development of urban ecosystems, significantly enhancing the ecological environment and residents’ quality of life. To scientifically improve urban park management and ensure long-term sustainability, this study aims to establish a framework for understanding and predicting residents’ spatial perceptions in urban parks. Overcoming the constraints of traditional empirical research, this study conducted a questionnaire survey involving 701 residents from Beijing Chaoyang Park, Shanghai Century Park, and Guangzhou Yuexiu Park from May to July 2024. By combining the semantic differential (SD) method, importance–performance analysis (IPA), and cognitive map methods, the study holistically assessed residents’ spatial perceptions and their variations in urban parks. The SD analysis highlighted perceptional differences in the three urban parks, revealing the needs for tailored planning considering personal characteristics and geographical location, which is essential for enhancing park services and overall satisfaction. Comparative analysis showed significant variations in the preferences in different resident groups, with Chaoyang Park facing a sense of deprivation due to weaker natural features, suggesting the critical role of natural elements in park design, while Century and Yuexiu Parks were highly valued for aligning park design with local needs and preferences. Cognitive maps reveal residents’ spatial perception of urban parks, particularly their significant differences in familiarity with the natural and social functions, artificial landscapes, and internal attractions of parks, which informs the integration of design elements that cater to varying preferences and foster a stronger sense of place. This study confirms the effectiveness of combining traditional methods with spatial perception analysis for quantitatively evaluating residents’ spatial perception, and provides useful references for the sustainable planning and management of urban parks.

Intergenerational sharing promotes social cohesion within communities by encouraging dialogue and understanding across different age groups. Nevertheless, existing research has inadequately delved into the human experiences and meaning-making processes that underpin intergenerational sharing, leading to a limited grasp of effective design intervention strategies in community spaces. This study aimed to explore the environmental and social factors influencing intergenerational interactions in community public spaces in Changsha, China, addressing two primary questions: (1) What environmental factors shape intergenerational sharing behaviors? (2) What design strategies can enhance intergenerational sharing in community public spaces? This research employed a mixed-methods approach, including qualitative observation and quantitative importance–performance analysis (IPA) through a survey of 212 residents, to investigate the intergenerational sharing needs of residents. To begin with, the study conducted a detailed analysis of the characteristics and variations in Changsha’s community public spaces. The finding revealed notable disparities in intergenerational sharing behaviors among three types of community spaces: traditional, commercial housing, and integrated neighborhoods. Through environmental behavior observation and IPA, key environmental factors influencing intergenerational sharing behaviors were identified, emphasizing areas for improvement. Based on these findings, the study proposed a design framework consisting of community planning and design, spatial layout and facility construction, and community management, with nine targeted strategies to optimize environmental factors for intergenerational sharing to cater to the unique characteristics of different community types. These findings can deepen our understanding of intergenerational sharing mechanisms and offer practical recommendations for fostering stronger interactions, providing valuable insights for future community public space design.

Historic districts are an important component of urban heritage, carrying the memory of the city. The study provides objective spatial level and subjective perception level analysis regarding the evaluation of the renewal of historic districts. We selected Qianmen Street, which is located on the central axis of Beijing, as the research subject. Space syntax was used to determine the importance of the main street to the district, and a kernel density analysis revealed that it was a poor tourist attraction. We used online comment data to establish an evaluation system, based on grounded theory, for the renewal of Qianmen Street. The evaluation system consisted of four primary indicators, including space creation, architectural style conservation, locality, and business management, as well as fifteen secondary indicators. Additionally, an importance–performance analysis (IPA) was used to conduct a quadrant analysis on tourist satisfaction evaluation indicators, in order to analyze influencing factors. The results show that tourists are most concerned about the dimensions of locality and business management, but the level of tourist satisfaction is low. The renewal of the Qianmen historic district should give priority to the creation of its historicity, cultural characteristics, and uniqueness, and should use a small-scale, gradual, and sustainable renewal method.

With the advent of artificial intelligence digitization, intangible cultural heritage faces challenges in preservation and transmission. Utilizing modern technology to achieve digital protection and dissemination has become a crucial issue today. This study enhances the digital inheritance and development of Chinese intangible cultural heritage paper-cutting art through generative AI technologies, specifically Diffusion and LoRA models. The Analytic Hierarchy Process (AHP) was employed to categorize the cultural value of paper-cutting, selecting four core elements: “Spring Festival”, “Chinese Zodiac”, “Women”, and “Birds and Flowers”. Based on these, eight LoRA models were developed to generate paper-cutting-style patterns (using the FLUX.1-dev and Stable Diffusion 1.5 models). In the user satisfaction assessment, the Importance–Performance Analysis (IPA) method was used to analyze four dimensions of the model experience. The results indicate that the LoRA model excels in generating detailed paper-cutting patterns and accurately reproducing cultural elements, particularly in the generation of complex Chinese character designs. User feedback suggests that the LoRA model effectively enhances the digital representation and dissemination of paper-cutting art, though there is room for improvement in terms of generation speed and ease of operation. This study provides a new technological pathway for the digital preservation of intangible cultural heritage and promotes the modernization of paper-cutting art transmission. Full article

Rural sport events can play an important role in the sustainable development of rural areas, and bring various benefits. The atmosphere of a rural sport event covers the character and feeling of a place and situation. The aim of this article is to assess the impact of rural sport event atmosphere on participants. Research was conducted using the IPA method (Importance–Performance Analysis). On 22 January 2022, 127 respondents assessed the atmosphere of a running sport event—before the run defining “importance”, and after the run defining “performance” (a survey questionnaire with a five-point Likert scale was used). The research covers three groups of factors: event organization (rules and safety, management and hosting, sport competition class), relationships between participants (integration, sharing passion, ability to compete), and event place (attractiveness of the area, attractiveness of the sport competition place, and the will to return to the place). For both the “importance” and “performance” scales, the examined factors received high values (from 3.80 to 4.77). The conducted research shows that atmosphere is a key element when building a rural sport event. Satisfaction with a running event has a positive impact on the perception of the event and its atmospheric components. Full article
