This study explores incomplete decision-making dynamics on reward-based crowdfunding platforms, focusing on temporal and social factors influencing backers' decisions. Utilizing the temporal aspect (i.e., pledging campaign phase) and social aspect (i.e., current pledged amount ratio) as stimuli within the stimulus-organism-response framework, our findings reveal that nearly 50.9% of respondents change their initial decisions, highlighting widespread incomplete information processing. Backers are more prone to altering decisions under heightened time pressure and display herding behaviors. Furthermore, backers exhibit an increased likelihood of changing decisions under heightened time pressure, coupled with a greater chance that the pledged goal amount will not be achieved. The study discusses theoretical and practical implications.

China and Southeast Asia share intimate relationships based on close spatial, temporal and human conditions. Thus, Southeast Asian studies in China boast of a long lineage of 'traditional', 'embryonic', 'closed' and 'opened' Southeast Asian studies. In the modern period the 'embryonic Southeast Asian studies,' professing conservative nationalism based on traditional Sino-centric perspectives, accumulated elementary knowledges on the history of Sino-Southeast Asian relations and Chinese communities in Southeast Asia. On the other hand, 'closed Southeast Asian studies' standing for radical Communism suffered from chronic stagnation. After the Reform and Opening, 'opened Southeast Asian studies' recorded impressive progress in the restoration and development of Southeast Asian studies. Nevertheless, 'opened Southeast Asian studies' are faced with some serious problems such as biased perspectives, traditional methods, and national subjects. Most of all, it is urgent to overcome Sino-centric perspectives on Southeast Asia. Despite the opening of Southeast Asian studies to the diverse methods of modern social sciences, descriptive studies prevail over analytical ones. Regardless of the diversification of subjects, national questions such as the overseas Chinese and cross-border nationalities are prone to excessive nationalism.

Urban air mobility (UAM) is emerging as an innovative transportation solution for cities. However, the potential noise impact on urban life must be carefully examined. Continuous exposure to UAM noise, with its unique frequency characteristics and temporal variability, may adversely affect citizens' health by causing sleep disorders, cardiovascular disease, and cognitive impairmenet, particularly in children. NASA has formed a UAM Noise Working Group to study this issue comprehensively. In Korea, the Seoul Metropolitan Government's UAM demonstration project is expected to accelerate related research and development. Scientific analysis, including noise measurement, prediction modeling, and health impact assessment, must be prioritized. Measures to minimize noise should be established based on this evidence, such as optimizing flight modes, developing noise reduction technologies, and establishing new noise management standards. Transparency and social consensus are crucial throughout this process. Expert review and open communication with civil society are necessary to address related concerns. Sharing demonstration project results and providing opportunities to experience UAM noise through digital twin simulations can help address public concerns and build social consensus. Proactively and scientifically tackling noise issues is essential for the sustainable development and successful integration of UAM into daily life.

The study reported in this paper aimed to evaluate the topics and opinions of COVID-19 discussion found on Twitter. It performed topic modeling and sentiment analysis of tweets posted during the COVID-19 outbreak, and compared these results over space and time. In addition, by covering a more recent and a longer period of the pandemic timeline, several patterns not previously reported in the literature were revealed. Author-pooled Latent Dirichlet Allocation (LDA) was used to generate twenty topics that discuss different aspects related to the pandemic. Time-series analysis of the distribution of tweets over topics was performed to explore how the discussion on each topic changed over time, and the potential reasons behind the change. In addition, spatial analysis of topics was performed by comparing the percentage of tweets in each topic among top tweeting countries. Afterward, sentiment analysis of tweets was performed at both temporal and spatial levels. Our intention was to analyze how the sentiment differs between countries and in response to certain events. The performance of the topic model was assessed by being compared with other alternative topic modeling techniques. The topic coherence was measured for the different techniques while changing the number of topics. Results showed that the pooling by author before performing LDA significantly improved the produced topic models.

This study is to investigate the previous cases of plural eclecticism through the works of Vivienne Westwood, who contributed to the spread of innovative and eclectic English fashion out to the world as well as to review plurality and its phenomena since the 20th century more systematically. In terms of research methodology, the phenomena of plural eclecticism were examined from social and cultural perspectives, whereas bibliographic research and case study were performed for the phenomena of eclecticism in fashion. From the perspective of plural eclecticism, the results from analyzing the works of Vivienne Westwood by the divisions of temporal eclecticism, spatial eclecticism, and contingent eclecticism are described in the following. First, Vivienne Westwood emphasized historicism tendency of temporal eclecticism. Her efforts to try to modernize history went beyond ages and social classes including men's clothing, prostitutes' costumes, craft items, and dresses for royal family. Second, her spatial eclecticism was reflected on the first collection themes inspired by the American Indians or borrowed from the names of Voodoo in the Tropics. Finally, infra-fashion as an expression of contingent eclecticism of Vivienne Westwood's works can be interpreted as plural eclecticism which shows contingent eclecticism and historic eclecticism at the same time. This study aimed at proving preceding implications concerning recent plural eclecticism through the analysis of the works of Vivienne Westwood who tried a radical design of plural eclecticism in an effort to modernize the tradition of England in the circumstances where a number of trends and styles exist together, with their own uniqueness and values.

The ephemeral and temporal nature of pavilions is the underlying motivation that led to the development of this paper. From the beginning of the industrial era through contemporary history, there have been many instances of architects attempting to rethink architectural design in the context of modern social, cultural, and technical imperatives. Today, the leading changes in humanity are accompanied by a revolutionary electronic digital medium. The pavilion has been in an amalgamation of architectural integration since the beginning of human history. World's Fairs/Expos have, since their establishment, served as international presentations of goods and achievements of particular nations. They became a popular stage wherein potential architectural achievements were showcased through the evocative architecture of pavilions. Due to the pavilion's "temporary nature," its coverage includes various perspectives: social, historical, geographical, post-colonial, iconographical, temporal, and ephemeral. It has also served as a receptacle due to its representational value at a given time. The pavilion has offered architectural designers, clients, and visitors a place to use their imaginations. Moreover, the architect's role in creating pavilions cannot be overestimated. Due to fact that they abound in symbolism, contemporary designs, and innovative solutions, pavilions often mirror modern mankind and plan for the next aesthetic revolutions and ideological architectural theories. To understand and appreciate architects' original intentions with their pavilions, this paper focuses on noteworthy pavilions that were created from the beginning of industrialization through the present. It explores and discusses the pavilion's characteristics, highlights the significance of its physical form as generated by a specific theme.

This paper reviews the future directions and perspectives on the soil environmental researches in the 21 century. Previously, the principal emphasis of soil environmental researches had put on the enhancement of food and fiber productions. Beside the basic function of soil, however, the societal needs on soil resources in the 21st century have demands for several environmental and social challenges, occurring regionally or globally. Typical global issues with which soil science should deal include food security with increasing agronomic production to meet the exploding world population growth, adaptation and mitigation of climate change, increase of the carbon sequestration, supply of the biomass and bioenergy, securing the water resource and quality, protection of environmental pollution, enhancing the biodiversity and ecosystem health, and developing the sustainable farming/cropping system that improve the use efficiency of water and agricultural resources. These challenges can be solved through the sustainable crop production intensification (SCPI) or plant welfare concept in which soil plays a key role in solving the abovementioned global issues. Through implementation of either concept, soil science can fulfill the goal of the modern agriculture which is the sustainable production of crops while maintaining or enhancing the ecosystem function, quality and health. Therefore, directions of the future soil environmental researches should lie on valuing soil as an ecosystem services, translating research across both temporal and spatial scales, sharing and using data already available for other purposes, incorporating existing and new technologies from other disciplines, collaborating across discipline, and translating soil research into information for stakeholders and end users. Through the outcomes of these approaches, soil can enhance the productivity from the same confined land, increase profitability, conserve natural resource, reduce the negative impact on environment, enhance human nutrition and health, and enhance natural capital and the flow of ecosystem services. Soil is the central dogma, final frontier and new engine for the era of sustainability development in the $21^{st}$ century and thus soil environmental researches should be carried according to this main theme.
