This work aims to demonstrate the use of electrochemical chloride extraction (ECE) to remove chloride ions away from the steel rebar in chloride-contaminated mortar and to mitigate the corrosion of the embedded steel.

To simulate salt contamination in concrete, sodium chloride was added at 0.5 per cent by weight of cement in the fresh mortar featuring a water-to-cement ratio of 0.45. The ECE treatments were varied at two electrical current densities (1 and 5 A/m²), using two electrolytes (0.1M NaOH and 0.1M Na₃BO₃ solutions) and for two periods (2 and 4 weeks). The average free chloride concentration in cement mortars before and after ECE treatment was quantified using a customized chloride sensor, whereas the spatial distribution of relevant elements was obtained using energy-dispersive X-ray spectroscopy. The effect of ECE treatment on the electric resistivity of mortar and the corrosion resistance of steel rebar was investigated by electrochemical impedance spectroscopy and potentiodynamic polarization measurements, respectively.

The experimental results reveal that the ECE treatment was effective in removing chlorides and in improving electric resistivity and compressive strength of the mortar, when using the sodium borate solution as the electrolyte. In this case, a 4-week ECE treatment at 1 A/m² decreased the free chloride content in the mortar by 70 per cent, significantly increased the Ca/Si ratio in the mortar near rebar, led to a more refined and less permeable microstructure of the mortar and significantly improved its compressive strength. The ECE treatment was able to halt the chloride-induced corrosion of steel rebar by passivation. A 4-week ECE treatment at 1 A/m² using sodium hydroxide and sodium borate solutions decreased the corrosion rate of rebar by 36 and 34 per cent, respectively.

This electrochemical rehabilitation of steel-reinforced concrete under chloride-contaminated condition is very effective in prolonging its service life.

Wine as a research topic continues to address a plethora of diverse contexts. In consideration of this scope and abundance of wine literature, this study aims to provide guidance for future meaningful contributions to this existing body of wine knowledge through a comprehensive scholarly review.

A total of 22 wine business, hospitality and tourism journals were selected and used to identify 739 refereed articles addressing wine-related topics over a 26-year period from 1990 to 2015. This was segmented using five wine research time frames, which were then separately investigated using content analysis and keyword network analysis.

Results support the importance for continued refinement of certain research areas to add understanding to wine research. In particular, the topics of marketing and tourism pertaining to wine research have fragmented into much more specialized sub-segments over this 26-year period.

Limitations include generalizability of findings because of the study’s use of 22 journals, along with the selected 26-year period. Future research should examine other time periods using other publications in peripheral and in non-related areas to seek topics potentially and inadvertently overlooked by this process. Significant topics and trends regarding wine research were identified and classified according to time periods. Information has been provided for future directions and new research agendas.

Based upon an examination of time periods segmented by half-decades, keyword network analysis was used to explore wine research trends. Using keyword network analytics, this method for identifying networks between key words produced findings that have brought the literature regarding wine research to a current status allowing academics to gain insights into potential direction for future research needs.

In view of the influences of online videos on the cultural tourism industry, this study aims to explore the mechanisms triggered by watching online video behaviors of fans. This study examines how fans who have watched celebrities’ online videos become tourists who attend concerts held at destinations based on celebrity and destination endorsements.

This study builds for celebrity and destination endorsements on online videos by combining media richness and source model theory. This research adopts partial least squares structural equation modeling to analyze the mechanism triggered by online media.

Watching online media influences celebrity and destination endorsements, which, in turn, affects the concert experience and intention to return to the destination. Results reveal less intertwined relationships between celebrity and destination endorsements and the complex mechanisms between the two endorsements.

With the rise in popularity of online media, online content has become a major source of information in the tourism industry and a means of enjoying travel seamlessly. This study highlights not only the role of “watching online videos” as one of the richest media but also the role of live concerts in cultural tourism for understanding complex cultural tourism.

Among others in South Vietnam, the Temple of Literature in Vinh Long is the only one that has preserved its original form and layout. As such in 1991, the temple was recognized by the Ministry of Culture as a national-level historical and cultural relic. Nevertheless, the temple has been neither studied nor documented to any great depth. Only a few historical descriptions for local tour guidebooks and photo catalogs exist. Therefore this paper aims to initially record heritage values, spatial characteristics and the process of major changes, while documenting the current state of the temple structure and carrying out on-site inspections to survey the buildings.

This paper outlines the collection of survey data through field survey and provides an overview of the existing significant heritage factors of the Temple of Literature in Vinh Long by comparative examination in relation to other surviving temples and analyzing its unique spatial characteristics and indigenous cultural decorations in detail.

Although the layout of the temples was influenced by the Chinese Confucius's principles and the notion of Feng Shui, it is evident from the study that the design of the temple has many architectural elements that reveal Vietnam's unique culture and local features. In particular, the Temple of Literature in Vinh Long was a symbol of feudal education, symbolizing sacred traditional values in the field of education for the people of Vinh Long province. Stone steles recorded names of all contributors related to the construction and restoration of the temple with sincere gratitude. Moreover, many of the decorative motifs contain many indigenous cultural and artistic values of Vietnam, reflecting traditional Vietnamese beliefs and ethnographic features.

By comparatively analyzing the temple with others, it reveals the unique spatial features, layouts, changes and evolutions of the temple. Unlike the oldest and the largest Temple of Literature in Hanoi, the temples in the South are much smaller in terms of complex sizes and the number of buildings. They are mostly composed of a singular structure, the Attained Talent House, with some basic gates and water features interwoven within the landscape of the site. Based on the elementary layout, some subsidiary buildings were added according to the needs and site conditions, and in accordance with the bilateral axis.

The awareness and preservation of the architectural features of the local temple are needed to protect heritage monuments and to enhance cultural resources as part of securing Vietnamese ideology for a longer period of time. While the interest in historic preservation and conservation activities of heritage buildings in Vietnam has slowly grown in attention over the last decade, it is evident that many opportunities remain. It is hoped that this research is a small step toward further research, education and advocacy in the preservation of historic buildings in Vietnam.

The introduction of Chinese Confucian thought to Vietnam was one of the most substantial influences in Vietnamese intellectual history. Despite being an important part of the nation's architectural, cultural and intellectual heritage sites, the study and documentation of the Temples of Literature have been relatively neglected or marginalized. Accordingly, this study is significant to reveal not only the values and unique heritage characteristics of the temple, but also to prioritize resources for continued study and preservation.

This study examines consumers' evaluations of product consumption values, purchase intentions and willingness to pay for fashion products designed using generative adversarial network (GAN), an artificial intelligence technology. This research investigates differences between consumers' evaluations of a GAN-generated product and a non-GAN-generated product and tests whether disclosing the use of GAN technology affects consumers' evaluations.

Sample products were developed as experimental stimuli using cycleGAN. Data were collected from 163 members of Generation Y. Participants were assigned to one of the three experimental conditions (i.e. non-GAN-generated images, GAN-generated images with disclosure and GAN-generated images without disclosure). Regression analysis and ANOVA were used to test the hypotheses.

Functional, social and epistemic consumption values positively affect willingness to pay in the GAN-generated products. Relative to non-GAN-generated products, willingness to pay is significantly higher for GAN-generated products. Moreover, evaluations of functional value, emotional value and willingness to pay are highest when GAN technology is used, but not disclosed.

This study evaluates the utility of GANs from consumers' perspective based on the perceived value of GAN-generated product designs. Findings have practical implications for firms that are considering using GANs to develop products for the retail fashion market.

This study focuses on Vietnamese international students who returned from their overseas doctoral education to home universities in Vietnam (henceforth Vietnamese overseas-trained returnees). The purpose is to explore the experience of these returnees “doing research” (i.e. being research active) when resuming a lecturing role at a Vietnamese regional university. In the context of research now receiving heightened attention in both the wider global higher education (HE) discourse and the Vietnamese HE sector, this study is timely and provides valuable insights.

In total, 76 Vietnamese overseas-trained returnees from varied disciplinary backgrounds completed a questionnaire on their research motivation and their perceived constraints doing research. Eighteen subsequently took part in semi-structured interviews. The study draws on the notion of human agency from the sociocultural perspective to understand the coping strategies of the Vietnamese overseas-educated returnees in response to the challenges they encountered.

The results show that the returnees' motivations to conduct research varied, fuelled by passion, but constrained by multiple factors. Time constraints, heavy teaching loads, familial roles and lack of specialized equipment are key inhibiting factors in re-engaging in research for these returnees. Addressing them necessitated a great deal of readaptation, renegotiation and agentive resilience on the part of the returnees in employing different coping strategies to pursue research.

The paper argues for a subtle understanding of the returnees' experience of re-engaging in research that is both complex and contextual. Implications are drawn for research development in the regional Vietnamese HE context and perhaps in other similar settings.

There is little empirical knowledge about how Vietnamese returned graduates – university lecturers – continue doing research after their return. Also underexplored in global discourse is research on foreign-educated returnees doing research, while they are an important source of human resources. The present study, therefore, fills these research gaps.

This paper aims to examine the management status quo of archaeological heritage in Vietnam seen in the case of Vuon Chuoi, a complex of Bronze Age sites located in Central Hanoi, which has been believed to be Hanoi’s first human settlement. Like other archaeological sites located in urban areas, this site has been under threat of destruction caused by land encroachment pressure. Although researchers have long waged a campaign for preservation, the dissensus among key stakeholders and the dispute over responsibility have left this site at the heart of an interminable polemic over legislation.

This research utilises a qualitative approach, and the primary data were collected throughout multiple field trips in 2019 and 2020. Several open-ended interviews were conducted with various state and nonstate actors involved in the Vuon Chuoi Complex’s management process. The discussion was also supported by analysing related legal documents retrieved from national archives and official online directories.

This paper dissects the current legislative and administrative framework applied in governing heritage in general and archaeological sites in Vietnam, in particular. The results indicate that existing flaws in Vietnam’s legal system are detectable, and the unsystematic organisation has led to deferment of the decision-making processes. Also, there is an apparent difference found in the attitude of the bodies in charge toward the treatment of listed and unlisted sites.

This research outlines that in the wake of urbanisation and industrialisation in Vietnam, a consensus among key stakeholders and an inclusive legal system are required to help preserve archaeological sites in urgent need of attention. Although several Vietnamese laws and regulations have been put into practice, they have shown critical barriers and gaps in conserving Vietnamese cultural heritage.

The present study aims to investigate resident attendees' perceptions and attitudes towards a traditional cultural festival. It further clusters the attendees and identifies the profiles of each cluster based on its demographic, attitudinal and behavioral variables.

The Drunken Dragon Festival, a traditional cultural festival in Macao SAR, which has been embedded in the local community for about a century, is used as a case. Data collected from 378 residents on the day of the festival were factor analyzed and then grouped by using cluster analysis.

A two-cluster solution revealed that the two groups, overall, had distinct demographic characteristics and had somewhat different perceptions and attitudes towards the festival.

The results not only show the overall perceptions of the Drunken Dragon Festival among the resident attendees, but they also imply that the government and the organizers need to communicate with and involve the two resident attendee clusters differently.

This study is one of the first attempts to investigate the residents' attitudes towards the transformational development of a traditional cultural festival as an effort to ensure the viability of intangible cultural heritage and to utilize it as a tourism resource.

The purpose of this paper is to explore the critical roles of emotional intelligence, increasing job demands behaviour and subjective well-being in teachers' performance throughout their gender.

In this study, the authors used multi-group structural equation modelling and mediation analysis of a sample of 602 primary school teachers in Iran.

This study found that emotional intelligence significantly affected teachers' performance. Teachers' emotional intelligence and increasing job demands behaviour were significant predictors of teacher performance in both genders. Furthermore, increasing job demand behaviour had a stronger mediating effect than subjective well-being on the relationship between emotional intelligence and teachers' performance in both genders.

This model is an attempt to examine possible gender differences on the relationships between teachers' emotional intelligence and their job performance by mediating roles of subjective well-being and increasing job demands behaviours in a specific societal and educational context.
