To support the International Maritime Organization’s (IMO) 2050 greenhouse gas reduction targets, hybrid propulsion energy management systems (EMS)—which integrate multi-energy coordination and dynamic scheduling—have become a critical pathway for enabling low-carbon transitions and improving energy efficiency in the maritime sector. This paper conducts a comprehensive and structured analysis of EMS technologies applied to ship hybrid propulsion systems. It evaluates the functional roles of EMS under varying system architectures, synthesizes mainstream energy management strategies, and identifies current technological bottlenecks, thereby contributing theoretical foundations for the green transformation of the shipping industry. The study first examines representative hybrid propulsion architectures, detailing their technical characteristics to clarify the functional positioning and optimization priorities of EMS in each configuration. It then reviews prevailing energy management and control strategies, with a focus on their integration with artificial intelligence (AI) and the emergence of adaptive and data-driven approaches. Finally, the paper identifies key challenges in hybrid propulsion EMS, proposes future research directions, and offers practical recommendations to support the advancement and implementation of intelligent energy management technologies in maritime applications.

This paper is devoted to synthesizing a new type of CDs (carbon dots) with excellent NIR (near-infrared) emission in a biological water environment synthesized from small molecules. Citric acid was adopted as the precursor and treated by one-pot hydrothermal process in DMF solution with the assistance of a microwave. Urea (MH) and ammonium fluoride (MF) were adopted as nitrogen sources to synthesize two types of CDs, respectively. These conditions contributed to generate nanostructured carbon with a higher content of Pyrrolic-N, enrich the functional groups, and exfoliate the ordered layerstacking structure, which finally contributed to the higher NIR absorption band at 808 nm. The physicochemical properties and photothermal conversion ability were fully evaluated by UV–Vis-NIR (ultraviolet–visible light-NIR) absorption and photothermal experiments. MF possessed stronger absorption property and temperature-rising effect in the NIR region than MH, but both exhibited desirable photothermal stability. Next, the in vitro and in vivo experiments demonstrated that both MF and MH exhibited no significant toxicity for cells. NIR irradiation on CDs solution displayed an excellent killing effect on HeLa (breast cancer) and MCF7 (cervical cancer) cells but strongly depended on the concentration of CDs. MH had a weaker killing effect on MCF7 cells compared with MF in the same concentration. But HeLa cells suffered death from lower concentration of MH under NIR irradiation. Both MH and MF exhibited excellent therapy effects and no obvious tissue damage for these major organs of nude mice and BALB/C mice. Above all, both MF and MH with excellent photothermal effect under NIR irradiation had desirable NIR-triggered therapeutic effect on MCF7 and HeLa cells, while they also exhibited good biocompatibility without NIR irradiation.

Hydraulic turbines can convert tidal current energy into electric energy, and the addition of a deflector cover to the turbine can improve the efficiency of the turbine's energy harvesting. The angle of the inlet section and the angle of the outlet section of the deflector will further affect the final energy-acquisition efficiency.A threedimensional numerical model for turbine flow field analysis is established, and the RNG k-ε turbulence model is selected by CFD method, and the best angles of inlet section and outlet section are analysed by the method of sliding mesh to obtain the best angle of inlet section and outlet section separately, and then three groups of angles are selected near the best angle of inlet section and outlet section to make orthogonal comparisons. The energy acquisition efficiency of the turbine is calculated at different angles of the inlet and outlet sections of the deflector, and the turbine streamline distribution, velocity and pressure maps are analysed with and without the deflector.The study shows that the deflector can play the role of convergence of the downstream flow, which can improve the efficiency of the turbine energy acquisition, and the maximum energy acquisition efficiency is at the inlet angle of 29° and the outlet angle of 40 °, and the maximum energy acquisition efficiency can be improved by about 32 percent.

PURPOSES : There has been increasing interest in South Korea on warm-mix asphalt (WMA) and cold-mix asphalt (CMA) technologies that allow production of asphalt pavement mixtures at comparatively lower temperatures than those of hot-mix asphalt (HMA) for use in pavement engineering. This study aims to evaluate the feasibility of replacing HMA pavement with WMA pavement with the goal of reducing CO2 emissions associated with asphalt production for road construction. METHODS : Changes in the dynamic modulus characteristics of WMA and HMA according to short-term and long-term aging were evaluated. In addition, the effects of water damage were evaluated for short- and long-term aging stages. RESULTS : For WMA, in the process of mixing and short-term aging, early-age dynamic modulus decreased owing to low temperature and reduced short-term aging (STA) time. This could result in early damage to the asphalt pavement depending on the applied traffic load and environmental load. CONCLUSIONS : Mastercurves of the dynamic modulus were used for comparative analysis of WMA and HMA. Compared to the dynamic modulus after STA of HMA, the estimated aging time determined by experiments for WMA to achieve the required stiffness was more than 48 hours, which is equiva-lent to approximately 4 to 5 years real service life when converted. It is considered that further studies are needed for performance optimization to achieve early-age performance of the asphalt mixes.

With the dramatic advance in artificial intelligence, the use of an AI anchor in the news industry is a subject of great interest. An AI anchor is a computer-generated news anchor that mimics the human voice, appearance, and facial expressions to present the news. As the focus of this study is to investigate how the news media utilize an AI anchor in the news program, the research questions are as follows: (1) What are the differences in news topics between AI and human anchors? (2) How does the viewership differ based on these topic choices, with a focus on the emotional impact?

In response to the increasing deployment of brand chatbots in the service sector, this study developed a conceptual framework to examine the psychological processes through which brand chatbots contribute to relationship building efforts. A 2 (interactivity: high vs. low) X 2 (anthropomorphic conversation style: warm vs. competent) between-subject design was conducted in the context of the coffee service business. The levels of interactivity in the chatbots were operationalized by altering the subdimensions of interactivity: modality (i.e., media richness, response latency), message (i.e., interdependency in message exchanges), and source (i.e., customization of content flow). Different linguistic elements (e.g., terms of address, vocabulary, punctuation, emoticons) were used to construct two sets of scripts that emphasized either warmth or competence of the chatbots. Based on the results of the pretests, four brand chatbots via Facebook Messenger were developed using the platform provided by GoSky AI Inc.

In this study, waste corrugated paper was used as carbon precursor with KOH-NaOH mixture (mole ratio was 51:49 and the melting point is 170 °C) as activator to prepare porous carbon at different reaction temperature and different mass ratio of KOH-NaOH mixture/waste corrugate paper fiber. The micro-morphology, pore structure information and composition of porous carbon were analyzed, and the formation mechanism of pores was investigated. The effect of activator amount and pyrolysis temperature on the morphology and structure of porous carbon were studied. The adsorption capacity of porous carbon was evaluated with the methylene blue as model pollutant. The effect of adsorbent amount, adsorption time and temperature on the adsorption performance of the porous carbon were analyzed. The maximum specific surface area is 1493.30 m2 ·g−1 and the maximum adsorption capacity of methylene blue is 518 mg·g−1. This study provides a new idea for efficient conversion and utilization of waste paper.

In recent years, globalisation has fostered ever more frequent and intimate interactions between states and societies in the Asia-Pacific region. Unfortunately, this has also increased the potential for disputes, particularly regarding international trade and human rights. The Asia-Pacific Dispute Resolution Program, which is run jointly by the Institute of Asian Research and the Peter A. Allard School of Law at the University of British Columbia, seeks to better understand, explain and predict when such disputes will arise, combining stateof- the-art approaches from law, political science, communications, sociology, international relations, economics and business. To manage-and ideally preventsuch disputes, the world is in urgent need of resolution approaches that meet the needs and expectations of the different cultures involved. The objective of the Program is to propose innovative interdisciplinary approaches to dispute resolution that international communities of scholars and policymakers can use to promote intercultural communication and reconciliation.

Although there are many international treaties and conventions offering protection for generic human rights that implicitly refer to older persons, these relevant provisions are scattered, porous and lack of practical operability, which fail to provide explicit, tailored, comprehensive and binding protection to older persons. In addition, there are some soft law provisions that guide the application of law and add to the overall protection of older people. However none of the documents contains legally binding obligations. Therefore, the protection of the rights of the elderly must be formulated as the “hard law” which defines the responsibilities of the state and clarifies the implementation mechanism at the international and domestic level. In other words, a legal system ought to be established to comprehensively protect the rights of the elderly, which is just the Convention on the Rights of the Elderly. This article attempts to present a proposal to create the right system of the Convention, which represents the core of this potential international treaty.

The recent fentanyl dispute between China and the US adds the academic value to the efforts to examine the respective legal regime of public international law and the WTO law on narcotics trafficking. On the one hand, public international law offers a comprehensive framework to address narcotics trafficking but as demonstrated by Chinese proofs, its function is undermined by weak enforcement. On the other hand, there exist some useful mechanisms in the WTO law to combat narcotics trafficking but their weaknesses can also be easily spotted. More importantly, the alarm of the global threat of illicit trade is ringing, which requires our raising awareness to it. Recently, the UNCTAD and the OECD have already taken the initiative to discuss the collective actions, by means of conferences or reports, to deal with illicit trade. In the long run, it will be indispensable to establish an operational governance framework on the international level to effectively curb illicit trade.

The act of refusal takes place in everyday lives, but it has been discussed to be a difficult speech act for nonnative speakers. This study seeks to investigate Korean EFL learners’ refusals in extended discourse along with their pragmatic perceptions. Sixteen college students were engaged in oral role-plays with two native English speakers and instructed to refuse the interlocutor’s request. The refusal performances were analyzed using conversation analysis framework with respect to the interlocutors’ different powers and the learners’ proficiency levels. Learners also participated in retrospective verbal reports. Findings depict different verbal and nonverbal features illustrating learners’ sensitivity towards higher status and their different linguistic abilities. Furthermore, their verbal reports revealed that despite their pragmatic awareness, learners were not fully equipped with appropriate L2 pragmatic knowledge.

Corporate social responsibility (CSR) is viewed as an internal marketing strategy (Bhattacharya, Sen, & Korschun, 2007; Shabnam, & Sarker, 2012). Research indicate that CSR implementation has a positive impact on employees, and enhance working satisfaction, corporate identity and organizational commitment （Koh and El’fred, 2001;Valentine et al., 2006; Martinez & Rodríguez del Bosque, 2013; Lee, Song, Lee, Lee, & Bernhard, 2013）. However, some studies suggest that CSR will not directly influence employee, related mediating factors and moderating factors need to be more discussed. The study apply regulatory focus theory as a framework for explaining moderator effect of promotion and prevention focus on employee perceived CSR and working satisfaction, organizational identity and trust. Promotion focus means that employees consider CSR promoting a better society and environment, and prevention focus represent CSR is for preventing falling behind industry, and public criticism. A questionnaire survey was employed in hospitality industry, questionnaire is design based on related literature (VandeWalle, 1997; Higgins et. al., 2001; Craig et.al., 2009; Huimin, & Ryan, 2011; Martínez, Pérez, & Rodríguez del Bosque, 2013; Paek, Xiao, Lee & Song, 2013; Fu, Ye & Law, 2014). And five subscales are contained in the questionnaire, including perceived CSR、regulatory focus、 working satisfaction 、organizational commitment and organizational trust. To analyse the reliability and validity of the questionnaire, a pilot study was conducted in September 2017. 120 questionnaires were collected, 105 valid questionnaires were subjected to a preliminary analysis, the official investigation was conducted during January and February in 2017. 450 questionnaires were distributed, and 389 valid questionnaires were collected, a recovery rate of 86.4%. A significant partial correlation was found between perceived CSR and working satisfaction(ΔR2=.31, p<.000)、organizational commitment (ΔR2=.22,p<.000) and organizational trust (ΔR2=.27, p<.000). Hierarchical regression analysis was further used to estimate moderation effect of regulatory focus, the study find that moderation effect on the relationship between CSR and and working satisfaction(ΔR2=.02, p<.01)、organizational commitment (ΔR2=.06, p<.01) and organizational trust (ΔR2=.06, p<.01). The research finding shows that working satisfaction, organizational commitment and organizational trust are more influenced by the organization's CSR implementation while employees have positive interpretation and recognition of CSR. Therefore, the organization should fully communicate about the purpose and value of CSR, so that employees can identify with and support the organization's CSR, and then CSR can achieve the function of internal marketing. If employees think that the organization's implementation of CSR is only an obligation or only satisfies the social perception, there may be less positive impact of CSR on employees. Regulatory focus theory is suggested to apply on future consumer study.
