The purpose of this paper is to make research on causing mechanism of meteorological disaster as well as the components of meteorological disaster system and their semantic relationships. It has important practical significance due to the urgent need of further providing support for pre-assessment of influences of disastrous weather/climate events and promoting the level of emergency management.

This paper analyses the occurrence regulations and components of meteorological disasters and proposes the concept of meta-action. Ontology modelling method is adopted to describe the components and relationships among different parts comprising meteorological disaster system, and semantic web rule language is selected to identify the implicit relationships among the domain knowledge explicitly defined in ontology model. Besides, a case is studied to elaborate how to provide logic and semantic information support for comprehensive risk assessment of disastrous weather/climate events based on rule-based ontology reasoning method. It proves that ontology modelling and reasoning method is effective in providing decision makings.

This paper provides deep analyses about causing mechanisms of meteorological disasters, and implements information fusion of the components of meteorological disaster system and acquisition of potential semantic relations among ontology components and their individuals.

In this paper, on the basis of analysing the disaster-causing mechanisms, the meteorological disaster ontology (MDO) model is proposed by using the ontology modelling and reasoning method. MDO can be applied to provide decision makings for meteorological departments.

This paper aims to explore a structural optimization method to achieve the lightweight design of an aviation control stick part manufactured by laser powder bed fusion (LPBF) additive manufacturing (AM). The utilization of LPBF for the fabrication of the part provides great freedom to its structure optimization, further reduces its weight and improves its portability.

The stress distribution of the model was analyzed by finite element analysis. The material distribution path of the model was optimized through topology optimization. The structure and size of the parts were designed by applying honeycomb structures for weight reduction. The lightweight designed control stick part model was printed by LPBF using AlSi10Mg.

The weight of the control stick model was reduced by 32.64% through the optimization method using honeycomb structures with various geometries. The similar stress concentrations of the control stick model indicate that weight reduction has negligible effect on its mechanical strength. The maximum stress of the lightweight designed model under loading is 230.85 MPa, which is 61.81% larger than that of the original model. The lightweight control stick part manufactured by LPBF has good printability and service performance.

A structural optimization method integrating topology, shape and size optimization was proposed for a lightweight AlSi10Mg control stick printed by LPBF. The effectiveness of the optimization method, the printability of the lightweight model and the service performance of LPBF-printed AlSi10Mg control stick was verified, which provided practical references for the lightweight design of AM.

We performed a bibiometric analysis on urbanization research based on the 3,058 peer-reviewed articles in the SCI and SSCI database from 1984 to 2013. Our analysis revealed document types, scientific outputs, subject categories, major journals and major authors, geographic distribution, highly cited papers and citation networks and temporal trends in keywords burst. Growth of article output has emerged since 1990, and went through two development stages. Environmental sciences, urban studies and ecology came out the most urbanization articles and Landscape and Urban Planning was the most productive journal in urbanization studies. Tothmeresz B was the most prolific author. USA was the most productive country, but Chinese Academy of Sciences was the most high-producing institution. Three streams were identified among the 65 most cited articles in the LCS historiography, and Schueler’s (1994) article has the strongest bursts. A keyword analysis revealed that the “China”, “city” and “globalization” are the research hotspots in the future.

To accelerate the development of low-carbon industry in Zhaoqing City, transform the mode of economic growth, and promote industrial transformation and upgrading, the SWOT analysis method was applied.

While science has researched the impact of air pollution on human health, the economic dimension of it has been less researched so far. Renewable energy consumption is an important factor in determining the level of life expectancy and reducing health expenditure. Thus, this study aims to investigate the impact of renewable energy, carbon emissions, health expenditure and urbanization on life expectancy in G-7 countries over the period of 2000–2019.

This study has adopted a novel Method of Moments Quantile Regression (MMQR). Furthermore, as a robustness check for MMQR, the fully modified ordinary least square, dynamic ordinary least squares and fixed effect ordinary least square estimators have been used.

The results indicated that renewable energy consumption, health expenditure and urbanization lead to an increase in life expectancy across all quantiles (5th to 95th), whereas higher carbon dioxide emissions reduce life expectancy at birth across all the quantiles (5th to 95th).

The empirical findings conclude that governments should recognize their potential in renewable energy sources and devise policies such as tax-related regulations, or relevant incentives to encourage further investments in this field.

This paper in comparison to the other research studies used MMQR to investigate the impact of factors affecting life expectancy. Also, to the best of the authors’ knowledge, so far no study has investigated the impact of renewable energy on life expectancy in G-7 countries.

Industrial land renewal is a significant constituent of urban environment and sustainable development. Most implementation in planning of renewal of industrial land has been mainly conducted at the site level of industrial zones or parks and the larger scale of township planning deserve further attention in China. To fill this gap, this paper aims to investigate the implementation of industrial land renewal for a whole urbanized area under the township master planning.

This study introduces a progressive approach to identify and evaluate the renewal of industrial land in township master planning to move toward a more practical understanding of industrial transition. The authors chose a typical industrialized town, Lijia in Changzhou City, under the development model of “Southern Jiangsu” to explain the measurement and assessment framework to identify and evaluate the renewable industrial land. Synthesizing the idea of sustainable development, the authors investigated the renewable industrial land with an econometric model including multiple-indexes of economic, social and ecological aspects, field observations and depth interviews.

The analysis demonstrated the spatial heterogeneity and complex generous structure of industrial land renewal in developing countries. It pointed out the major responsibility of enterprises as main industrial land users and indispensable responsibility of government and society. Following the idea of organic concentration and avoiding one-size-fits-all kind of deal, the master planning of Lijia emphasized the connection of industrial land and the combination of market force, social force and government regulation.

With original data and discussion, the authors provide more scientific renewal strategies for planners in sustainable development.

Satisfying the gastronomy experience of tourists becomes the most important strategic aim in the hospitality and tourism industries. This study attempts to prove that there is a distinct and specific market segment related to gastronomy from the overall number of tourist arrival of Jeonju City. Furthermore, this study investigates the different factors that affect the overall experience of tourists. The focus of the study is Jeonju City, a popular gastronomy destination in South Korea.

Survey questionnaires were distributed to 680 tourists in Jeonju City during two survey periods. Descriptive statistics and regressions were utilized to treat the data. The predictors that affect the overall experience of tourists were identified through the different literature. The hypotheses were formulated and tested to examine the relationship between the assessments of the distinct gastronomy-tourist market and tourists' overall experience.

The results indicate that there are 17.20% of the respondents indicated that their main reason for traveling was for the food. Descriptive statistics revealed that local food satisfaction, destination image perceived quality, perceived value, tourist expectations, and costs and risks have a positive and significant influence on tourist overall experience.

The findings of this study could provide guidelines for both the hospitality and tourism industries of the country, and tourist destination operators to further positioned approaches to satisfy gastronomy tourists in the “new normal”.

Tourism researchers proposed that service quality dimensions of tourist destinations can contribute in developing a favorable or unfavorable image among travelers which affect visitors’ loyalty or disloyalty as well as destination image. However, such claims are seldom evaluated into in avitourism locations, which are a niche tourism, but fast growing. The purpose of this study is to examine the relationship between service quality, visitor satisfaction and destination image and destination loyalty among avian tourists.

Following a positivist research philosophy with a quantitative, cross-sectional descriptive study design, the study addressed five direct and two indirect relationships in the model. The research followed expectation dis-confirmation theory of Gartner to test the theoretical model. Following purposive sampling, a sample of 384 international avitourists was collected from five avitourism locations of Malaysia. The study applied SmartPLS SEM to analyze the data.

The results show that the service quality provided by the park management has a positive impact on visitor satisfaction, destination image and destination loyalty. The study also shows partial mediation effect of visitor satisfaction on destination image and destination loyalty among avitourists. The study extends practical, policy and theoretical implications to the stakeholders of avitourism.

The study limits the possibility for generalization of the findings into five avitourism sites located in three states of Malaysia. Hence, the scope of the study needs to be augmented with samples from more regions to meet the expected generalization. Add to the point, this study lacks qualitative data observations to get an in-depth understanding of the issues pertaining to visitor’s expectations on serviced quality, satisfaction, destination image and loyalty. Hence, it is suggested that more qualitative research interventions need to be made with the tools of in-depth interviews, content analysis and with the method of focus group discussions and Delphi applications.

This study provides the park management a clearer understanding on service quality critical factors in enhancing the satisfaction of avian tourists and building a better avitourism destination image and destination loyalty. The avitourism park management may look into the services for these niche tourists, as these resources are directly linked to nature-based tourism with its diverse requirements to keep visitors satisfied. Park authorities require a sound understanding and skills in managing the biodiversity of the natural resources, birds and animals, to match their services with tourists’ expectations.

Biodiversity is important in supporting vital ecosystem services (ES) for human as well as animals. The study has its social implications in generating a greater number of employment opportunity for people surrounding the area of avian destinations preserving the biodiverse area. The people in the surroundings area of avitourism locations will get better employment opportunity as guides and nature trail experts, if the avian tourism develops in its real principle.

Avitourism is a niche tourism. The expectations of the visitors of avitourism locations are entirely varied in comparison with general tourism. Very less studies focused into expectations of the visitors linking human factor of service quality, emotional intelligence, visitor satisfaction, etc. like dimensions that will contribute into dynamic destination image and destination loyalty among avitourists. With the support of quantitative research tools, representative sampling and theoretical selection, the study findings are original in their form, ensuring external validity further to generalize into other birdwatching locations across the countries. The study observations are highly valuable to all stakeholders of avitourism.
