A vertical greening system is becoming increasingly crucial in resolving the energy crisis and environmental problems in a sustainable ecosystem. Researchers have conducted a comprehensive study on vertical greening systems from technology, functional and architectural perspectives. These include ecological, economic and social functions. Most of the current studies emphasize the benefits of vertical greening systems to the environment, while vertical greening technology and its socio-economic benefits receive insufficient attention. In order to study the vertical greening field in depth, this paper comprehensively and systematically summarizes vertical greening technology and functions. Meanwhile, based on the Web of Science (WOS), CiteSpace was used to analyze the relevant literature in the vertical greening field from 2012 to 2022, to explore the hot spots, development status and future trends of vertical greening technology, and to build a knowledge map in the vertical greening field. The research shows that as a low impact development technology, the vertical greening system has received the most extensive attention in the past few years. Air quality, microclimate regulation and energy have always been the focus and hot issues of people’s attention. The future research directions are cooling effect, active system and indoor space. This study is aimed at promoting the future development of vertical greening system technology and providing reference and direction for researchers, planners and developers, as well as individuals interested in future urban and rural planning.

A large number of intangible cultural heritages (ICH), In the development process of the evolution of world history, have been born. In addition, these heritages preserve the most precious part of historical civilization and have high research value. However, in social modernization, these ICHs are gradually being destroyed, and their preservation is becoming increasingly difficult. The protection of ICH cannot be relaxed at any moment. With the progress of science and technology, digital technology has become one of the means to protect ICH, and also explored new ways for the inheritance of ICH. Therefore, it is necessary to use modern information technology to store and preserve ICH. With the rapid development of the information age, digital implantation technology has gradually entered all aspects of life. This technology was effectively applied to preserve animation in the early days effectively, later researchers found that this technology has an excellent effect on the preservation of ICH, so it has been widely used. This paper firstly summarizes the current domestic ICH protection situation and the corresponding foreign policies. On this basis, digital implantation is applied to the relevant core technologies of ICH protection. The Digital implantation technology model of ICH is analyzed to protect the current ICH effectively and will promote the sustainable development of ICH.

The theory of sustainable business process reengineering has been widely applied in various disciplines and has achieved outstanding results. The theory is used to the research of product innovation design method in this work, and the entire process of product innovation design method is reshaped, bringing new development and new direction for product innovation design. Redesign processes in line with societal trends and in a sustainable direction. Furthermore, it may effectively address the inadequacies of conventional design methodologies during the application process. Then, increase corporate efficiency in order to accomplish significant improvements in enterprise cost, quality, service, and speed. The study applies the systematic induction method, research analysis method, and other comprehensive research methods to analyze and study the existing design process and method, as well as excavate the shortcomings and limitations that exist in the process's application of the existing design method. Based on the BPR theory, the sustainable innovation design method for full chain products is divided into five design processes: scenario implantation, requirement extraction, functional determination, structural optimization, formal innovation, and material selection. In addition, the feasibility and accuracy of this method are verified through lifesaving equipment cases. Secondly, three principles for sustainable product innovation design were proposed. On the one hand, products made by designers and college students can truly meet customer needs, generate disruptive innovative designs, and improve the market competitiveness of industrial products. On the other hand, design is no longer a single stage, but a complete, systematic, and comprehensive set of design processes aimed at improving design efficiency and achieving sustainable product development.

Introduction: With the rapid advancement of digitalization and an aging population, China faces unprecedented challenges in older adults’ digital cultural adaptation. The “54th Statistical Report on China’s Internet Development” reveals that individuals aged 60 and above constitute 14.3% of total internet users. However, significant barriers persist in their digital participation, necessitating a deeper understanding of their adaptation process and needs.Methods: This study employs the KANO model to assess older adults’ digital cultural adaptation. A total of 205 respondents participated in a questionnaire survey, with data analyzed using the highest frequency method and the Better-Worse coefficient. The study categorizes digital cultural needs into three dimensions: must-be requirements, one-dimensional requirements, and attractive requirements.Results: The findings indicate that: 1. Older adults’ digital cultural needs comprise must-be requirements (basic functional design, 47.8%), one-dimensional requirements (social participation, 36.1%), and attractive requirements (innovative experiences, 66.8%). 2. Intergenerational cultural cognitive differences, digital skill levels, and the urban–rural digital divide significantly impact their adaptation process. 3. While respondents positively evaluate digital life satisfaction, personal adaptation, and digital content diversity, they express dissatisfaction and expectations regarding family guidance, age-friendly digital services, and the role of digital content in improving life quality.Discussion: The results highlight the need for targeted strategies in technical support, content design, and service provision to enhance older adults’ digital cultural adaptation. Addressing group-specific needs and preferences through coordinated measures can improve digital inclusion, foster intergenerational cultural integration, and optimize digital cultural service systems. This study offers valuable theoretical insights and practical implications for advancing policies and initiatives that support older adults in the digital era.

Digitalization and population aging are profoundly reshaping contemporary Chinese society, with 14.3% of internet users now aged 60 and above. This study examines elderly Chinese individuals' adaptation to the digital environment through a survey of 205 participants aged 60 and above. Findings reveal widespread basic digital usage (88.78% use smartphones) but limited advanced engagement. While intergenerational support is the primary learning channel (87.32%), significant barriers exist, including communication difficulties and psychological concerns. Digital services' age-friendliness (satisfaction 2.92/5) requires improvement, particularly in accessibility features. The study recommends enhancing age-friendly design and optimizing support systems to promote digital inclusion among the elderly.
