Safety Aspects of Sodium-Ion Batteries: Prospective Analysis from First Generation Towards More Advanced Systems

After an introductory reminder of safety concerns pertaining to early rechargeable battery technologies, this review discusses current understandings and challenges of advanced sodium-ion batteries. Sodium-ion technology is now being marketed by industrial promoters who are advocating its workable capacity, as well as its use of readily accessible and cheaper key cell components. Often claimed to be safer than lithium-ion cells, currently only limited scientifically sound safety assessments of sodium-ion cells have been performed. However, the predicted sodium-ion development roadmap reveals that significant variants of sodium-ion batteries have entered or will potentially enter the market soon. With recent experiences of lithium-ion battery failures, sodium-ion battery safety management will constitute a key aspect of successful market penetration. As such, this review discusses the safety issues of sodium-ion batteries, presenting a twofold innovative perspective: (i) in terms of comparison with the parent lithium-ion technology making use of the same working principle and similar flammable non-aqueous solvent basis, and (ii) anticipating the arrival of innovative sub-chemistries at least partially inspired from successive generations of lithium-ion cells. The authors hope that the analysis provided will assist concerned stakeholders in the quest for safe marketing of sodium-ion batteries.

Protection of Seafarers' Rights and Interests by International Treaties

In 2006, the ILO adopted the Maritime Labour Convention, which has had an important impact on the rights of seafarers worldwide and the promotion of the international maritime industry. In recent years, China's labor and social security legal system has been gradually improved, and legal norms such as the Regulations on Seafarers and the Maritime Traffic Safety Law have been promulgated and implemented successively, laying a certain foundation for the system of labor norms for seafarers. However, these special legislation has some limitations, such as not strong operability and not identical with the international treaty system. This paper mainly studies the framework structure and implementation mechanism of maritime labor conventions, finds out China's application method of international law, and puts forward the shortcomings of China's implementation process and corresponding countermeasures and suggestions suitable for the current situation of Chinese seafarers. By combining theory with practice, this paper uses literature analysis and analysis deduction to find out the strategies that can optimize the implementation mechanism in China. At present, China has made a lot of preparations for the implementation of maritime labor conventions, carried out a lot of legislative activities, and has already acquired relevant legislative experience and technology. Improving the labor supervision system and making full use of the tripartite mechanism platform and industry associations are the top priorities for China to better implement international conventions and protect the rights and interests of seafarers in the next stage.

Study on Optimization of Land Use Structure in Fujian Province Based on Low-Carbon Perspective

Carbon peaking and carbon neutrality strategies are pivotal in addressing climate change. Optimizing land use structure is a fundamental approach to achieving low-carbon development within a given territory. This study focuses on Fujian Province as the research subject, predicting carbon emissions for the next decade by analyzing the correlation between land use types and carbon emissions using the gray model. This analysis is based on land use panel data spanning from 2007 to 2021. The study applies the FLUS-Markov model to simulate Fujian’s land use in 2030. A multi-objective optimization model is developed from a low-carbon perspective, integrating carbon emissions, economic, and ecological factors. The study explores land use under three scenarios: natural development scenario (NS), low carbon scenario (LCS), and comprehensive scenario (CS). Findings highlight the relationship between land use-related carbon emissions, urbanization, and relevant policies in Fujian. The FLUS-Markov simulations suggest that under the NS scenario, carbon emissions in 2030 will reach 77.829 million tons, an increase of 11.013 million tons from 2020. In contrast, the LCS demonstrates that optimizing land use structures can effectively balance carbon reduction, economic growth, and ecological preservation. Under the CS, 2030 emissions could be reduced by 7.2854 million tons while maintaining economic and ecological benefits. Despite variations in construction land expansion across these scenarios, all follow a “one belt, one core” development pattern. The study concludes with policy recommendations, including industrial layout optimization and clean energy promotion. These findings support the alignment of land use optimization with Fujian’s future development needs, offering guidance for land-use planning and policies focused on low-carbon objectives.

Comparative analysis of the growth differences between hybrid Ningdu Yellow chickens and their parentals

Although the local high quality chicken breed in China has excellent flavor, its growth rate is inferior to that of foreign breeds. To improve the growth rate of local chicken breeds, it is crucial to study the mechanism of chicken muscle development. Herein, Ningdu Yellow chicken was used as the research object, and a new hybrid breed (W) was obtained by crossing the G, H and D lines, which combined the excellent physiological characteristics of its parents. Combined analysis of Ningdu Yellow chickens and their parents was carried out. Chickens from 105-day-old lines (W, G, H) were selected, and breast meat and serum were extracted for transcriptome sequencing and metabolome determination to study their growth differences. The live weight, carcass weight, half-eviscerated weight, eviscerated weight, and breast muscle weight of W were significantly higher than those of G and H. Differential expression analysis identified 1700 differentially expressed genes (DEG), and gene ontology and kyoto encyclopedia of genes and genomes (KEGG) analyses identified 33 and 1 pathways related to growth and development and steroid biosynthesis, respectively. Next, pairwise analysis identified 57 KEGG pathways, among which the MAPK signaling, steroid hormone biosynthesis, tight junction, and PPAR signaling pathways were involved in growth and development. Cluster analysis found that genes highly expressed in the W group were associated with regulation of the actin cytoskeleton, riboflavin metabolism, steroid biosynthesis, and glycerophospholipid metabolism. The top 2 clusters obtained by protein-protein interaction analysis were important for the growth and development of chickens. Finally, the metabolomic analysis found key differentially accumulated metabolites (DAM) that might be account for the growth differences. Further integrated analysis identified key DEGs and DAMs that might be responsible for the observed growth differences. This study identified genes governing growth traits in Ningdu Yellow chickens, laying a theoretical foundation for the development of chicken breeding, the utilization of hybrid supporting lines, and promotion of the Chinese chicken industry.

General characteristics of investment law in India

The aim of the work is a comprehensive analysis of investment law in India. The methodological basis of the study are official websites of specialized institutions, laws, analytical reports, articles by other scientists, etc. According to the results of the conducted research, it was found that two main legislative acts regulate investment activities in India. The first piece of legislation is the Foreign Exchange Management Act, 1999, the main objective of which is to promote foreign trade and foreign exchange and to develop and maintain the foreign exchange market in India. According to Section 5 and 6 of the Law, operations with a current currency account are allowed only on the condition that they do not have any restrictions (criminal, state, etc.). Capital account transactions mean transactions during which changes in assets or liabilities occur (referring to liabilities of resident and non-resident persons in relation to assets). The second act – Consolidated Policy on Attracting FDI in India by the Department of Trade and Industry Promotion 2020 – includes clarification of all investment norms. The policy update is in line with the policy of need to attract FDI to India, as per the plans of the Department. In conclusion, it was found that the legal system of India is based on common law, which is based on English law. According to the Constitution of India, a quasi-federal structure has been approved, which provides for the division of legislative power between the central government and the individual states. Foreign direct investment in India is governed by two main pieces of legislation. The first is the Foreign Exchange Management Act of 1999, its main objective is to facilitate foreign trade and foreign exchange and to develop and maintain the Indian foreign exchange market. The second – Consolidated policy on attracting FDI to India. Attracting foreign direct investment in India is possible in two ways: automatic investment of FDI and obtaining permission for FDI.

Protective Effects of an Octapeptide Identified from Riceberry™ (Oryza sativa) Protein Hydrolysate on Oxidative and Endoplasmic Reticulum (ER) Stress in L929 Cells.

Reactive oxygen species (ROS) play a critical role in oxidative stress and cellular damage, underscoring the importance of identifying potent antioxidants. This research focuses on the antioxidant capabilities of Riceberry™-derived peptides and their protective effects against oxidative and endoplasmic reticulum (ER) stress in L929 cells. By simulating human digestion, Riceberry™ protein hydrolysate was generated, from which antioxidant peptides were isolated using OFFGEL electrophoresis and LC-MS/MS. Notably, an octapeptide (VPAGVAHW) from the hydrolysate demonstrated significant antioxidant activity, particularly against oxidative stress induced by iodoacetic acid (IAA) or hydrogen peroxide (H2O2) and ER stress caused by tunicamycin (TM) in L929 cells. This peptide's effectiveness was evident in its dose-dependent ability to enhance cell viability and mitigate stress effects, although its efficiency varied with the stress inducer. Our study suggests that Riceberry™-derived peptides could serve as a promising natural antioxidant with potential benefits for health promotion and applications in the food industry, offering an environmentally friendly alternative to synthetic antioxidants.

Politics and dinner tables do mix! exploring the role of consumers’ political orientation in plant-based food promotion at restaurants

Plant-based food refers to a diet focused on consuming primarily plant-derived ingredients for health, environmental, and ethical reasons. Since there is a growing recognition regarding the significant correlation between sustainable consumption and consumers' political inclinations, this study aimed to identify effective ways to promote plant-based food in a restaurant setting by analyzing the relative persuasiveness of advertisements in terms of three variables: consumer political orientation (liberal vs. conservative), regulatory focus (promotion vs. prevention), and message type (health vs. taste). This study confirms that there is a significant two-way effect between political orientation and regulatory focus on consumers’ attitude and purchase intentions toward plant-based food. Additionally, this two-way effect between political orientation and regulatory focus varies depending on the type of message. The mediating role of goal relevance was confirmed as well. The study provides implications for effective marketing communication in the context of plant-based food promotion in the foodservice industry.

Proteomic Analysis of the Characteristic Flavor Components in Bacillus subtilis BSNK-5-Fermented Soymilk.

Fermentation with Bacillus subtilis significantly enhances the physiological activity and bioavailability of soymilk, but the resulting characteristic flavor seriously affects its industrial promotion. The objective of this study was to identify key proteins associated with characteristic flavors in B. subtilis BSNK-5-fermented soymilk using tandem mass tag (TMT) proteomics. The results showed that a total of 765 differentially expressed proteins were identified. Seventy differentially expressed proteins related to characteristic flavor were screened through Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. After integrating metabolomics data, fifteen key proteases of characteristic flavor components in BSNK-5-fermented soymilk were further identified, and free ammonia was added. In addition, there were five main formation mechanisms, including the decomposition of urea to produce ammonia; the degradation of glutamate by glutamate dehydrogenase to produce ammonia; the degradation of threonine and non-enzymatic changes to form the derivative 2,5-dimethylpyrazine; the degradation of valine, leucine, and isoleucine to synthesize isovalerate and 2-methylbutyrate; and the metabolism of pyruvate and lactate to synthesize acetate. These results provide a theoretical foundation for the improvement of undesirable flavor in B. subtilis BSNK-5-fermented soy foods.

“It’s changing our lives, not for the better. It’s important that we have a say”. The role of young people in informing public health and policy decisions about gambling marketing

BackgroundMarketing has a significant impact on the normalisation of gambling for youth across the globe. This has included shaping positive attitudes towards gambling, as well as increasing the social and cultural acceptance of gambling – particularly aligned with valued activities such as sport. Because of this, public health experts argue that gambling marketing poses a significant risk to the health and wellbeing of youth. While young people are increasingly exposed to, and impacted by marketing for gambling products, they are rarely consulted about policy issues and options. This study aimed to explore young Australians’ perceptions of current policy responses to gambling advertising, whether they thought young people should be involved in discussions and decisions about gambling marketing regulations, and their perceptions of the duty of governments to protect young people from gambling industry marketing strategies.MethodsQualitative focus groups (n = 22) were held with n = 64, 12–17 year olds in the Australian states of Victoria and New South Wales. Participants were asked to reflect on current gambling policies, particularly relating to marketing, what they thought should be done about gambling marketing, and if and how young people should be included in public health responses to gambling. An interpretivist ‘Big Q’ approach to reflexive thematic analysis was used.ResultsYoung people highlighted the need for more effective regulations around the content and frequency of gambling marketing. They also wanted to see more realistic representations of the negative impacts of gambling to counter persistent positive commercial marketing messages. Most thought that young people should be given an opportunity to have a say about responses to gambling due to their unique experiences. Participants identified mechanisms to increase young people’s engagement in decision making, such as direct lines of communication to different levels of government, involvement in research, and diversifying ways of engagement. Specific recommendations included more regulatory action such as bans on gambling advertising.ConclusionsCreating formal structures that facilitate the inclusion of young people’s perspectives in decisions made about gambling can result in more innovative and effective strategies to prevent the harms from gambling industry products, promotions, and practices.

Aesthetic Transcendence: Fashion's Evolution, Philosophical Reflections, and Societal Impact

This research paper explores the evolution of fashion from its utilitarian origins over 170,000 years ago to its contemporary role as a symbol of cultural expression and individual identity. Tracing the historical trajectory through ancient civilizations, the Renaissance era, and significant societal shifts post-World War II, the study highlights the dynamic interplay between culture, external forces, and fashion. It also delves into the commodification of beauty in the contemporary era, examining the persuasive techniques used by beauty brands in advertisements, such as leveraging emotional states to connect deeply with consumers. The global impact of beauty standards and the perpetuation of white-centric ideals are scrutinized, emphasizing influential figures like Marcus Garvey, who challenged these norms. The study sheds light on the beauty industry's promotion of skin-lightening and hair-straightening products, particularly in Asian markets, and offers philosophical reflections on these beauty standards. Engaging with the works of Hume, Kant, Santayana, and Schiller, the paper dissects the subjective and objective dimensions of beauty, including Hume's emphasis on pleasure and pain, Kant's categorization of beauty, Santayana's concept of objectified pleasure, and Schiller's influence on German Idealism. It culminates with an exploration of Jean Baudrillard's "Death of the Real," examining the implications of a society immersed in creating identities detached from objective reality. This paper weaves together the historical evolution of fashion, beauty brand strategies, and philosophical reflections on beauty, offering a nuanced understanding of the complex relationship between aesthetics, identity, and societal perceptions.

Bottleneck to Success: Case Study on Scaling Up Issues of Indian Start-ups

The dynamic growth of start-up companies in India has significantly disrupted the business landscape. However, many start-ups encounter substantial setbacks during the scaling-up stage. This qualitative study explores the challenges faced by Indian start-ups as they scale their businesses. The findings reveal that the primary obstacles include the non-availability of financial resources, difficulties in acquiring the right talent, and challenges in achieving product acceptance. According to the Department for Promotion of Industry and Internal Trade (DPIIT), India is home to over 50,000 start-ups as of 2023, with a yearly growth rate of approximately 12-15%. Despite this robust growth, data shows that about 90% of Indian start-ups fail within the first five years, primarily due to scaling issues. This study highlights that limited access to financial resources remains a critical barrier, with start-ups often struggling to secure funding beyond the initial stages. Talent acquisition is another major hurdle, as start-ups compete with established companies for skilled professionals. Furthermore, gaining market acceptance for new products poses significant challenges due to high competition and market saturation. By developing a comprehensive model, the study demonstrates that government intervention can play a crucial role in addressing these challenges. Initiatives like the Startup India program, which offers tax benefits, easier compliance, and funding support, are steps in the right direction. Additionally, the results underscore the importance of clearly defining problem statements, exercising patience, and possessing a risk-taking ability as essential factors for the success of start-up companies.

Snus Use in Adolescents: A Threat to Oral Health.

Background: Snus consumption is increasingly popular, mainly among the youth, due to the promotion of the tobacco industry and the lack of knowledge regarding its adverse effects. Even though some of its systemic complications are common knowledge, the oral consequences are rarely known. Aim: Therefore, the objective of this study is to evaluate the oral health effects of snus consumption among a highly exposed group of adolescent athletes. Design: Participants received an interactive presentation, followed by interviews and dental screenings by young doctors to establish trust. They were categorized into groups based on the frequency of snus usage. The oral hygiene habits and status, snus consumption habits, and awareness about its adverse effects were evaluated. Results: Statistically significantly (p < 0.05), more regular snus users experience gum bleeding while tooth brushing than nonusers (60% and 37%, p = 0.004). Snus consumption and poor oral hygiene have a cumulative effect on oral health. Some young athletes experience ulcerous oral mucosal lesions coinciding with snus placement. Nonusers exhibit greater awareness of the adverse effects of snus than regular users (27% and 49%). Conclusions: Regular snus use negatively affects oral health, especially the gums. Early education is of the utmost importance in preventing snus usage by raising awareness.

Do government resource management policies influence green productivity? New perspectives from fintech and digital resource policy in China

Achieving sustainable development necessitates the exploration of innovative approaches towards low-carbon development and efficient resource management. By adopting the low-carbon city pilot project as a policy shock of Government Resource Management Policies (GRMP), we aim to scrutinize the nuanced impacts of GRMP on green productivity (GTFP). Using the difference-in-difference (DID) approach and panel data from 280 cities in China. Our findings reveal a significant relationship between GRMP and GTFP. In the immediate short-term, GRMP exhibits a negative effect on GTFP growth, followed by a long-term positive promoting effect. A detailed temporal analysis uncovers an “inverted N″ time-period effect of GRMP on GTFP growth. Further exploration into the mechanisms driving this influence reveals three key aspects: the reduction of natural resources consumption and the promotion of low-carbon production (LCP), low-carbon transportation (LCT), and low-carbon industries (LCI). While the regulated effect of financial technology resources on the relationship between GRMP and GTFP is positive but statistically insignificant, the regulated effect of digital resource policy emerges as positive and significant. Additionally, the regulated effect of mineral and forest resource coverage rate is positive but not statistically significant in the context of the influence of GRMP on GTFP. This comprehensive analysis contributes to our understanding of the dynamic interplay between policy interventions, resource management, and sustainable development in the Chinese urban landscape.

Can the sustainable development goal 9 support an untreated early childhood caries elimination agenda?

BackgroundEarly childhood caries (ECC) is a global public health challenge that requires innovation, infrastructure, and health system influences to bolster initiatives for its management and control. The aim of this scoping review was to investigate the published evidence on the association between ECC and the targets of the Sustainable Development Goal 9 (SDG9) concerned with industry, innovation, and infrastructure development.MethodsThe scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. A search was conducted in PubMed, Web of Science, and Scopus between July and August 2023 using a search strategy related to the promotion of resilient infrastructure, sustainable industries, scientific research and innovation, access to the internet and ECC. Only English language publications were included. Studies that solely examined ECC without reference to the SDG9 targets were excluded.ResultsThe search yielded 933 studies for review. After screening for the eligibility and removing duplicates, 916 unique articles remained for further screening. However, none of the identified studies provided data on the association between resilient infrastructure, sustainable industries, scientific research and innovation, access to the internet and ECC.ConclusionThere were no primary studies that assessed the association between ECC and SDG9, even though the plausibility of a potential relationship exists. Future studies are needed to generate evidence on the link between ECC and SDG9 as this link may contribute to the reduction in the proportion of children with untreated ECC.

Drivers of transportation CO2 emissions and their changing patterns: Empirical results from 18 countries

Transportation continues to be a significant contributor to CO2 emissions and may potentially be the final sector to reach its carbon peak in the future. Identifying the drivers of transportation CO2 emissions (TCE) and understanding their changing patterns is crucial to effectively control TCE. However, previous studies can only obtain fixed parameter values of TCE influencing factors throughout the study period, or although they can obtain the impacts of specific factors on TCE with accompanying changes over the years, they cannot conveniently clarify the changing patterns. Therefore, the key contribution of this study resides in providing a spatially explicit understanding of the heterogeneous primary drivers of TCE across countries, and in uncovering the temporal dynamics of these primary drivers' influences on TCE. The results show that at the country-group level (considering 18 selected countries as a group, collectively representing over 60% of global TCE), the drivers of TCE were GDP, energy intensity, and population in order of contribution. However, for developed countries, GDP and energy intensity contributed less to TCE than for developing countries. In addition, the influence of energy intensity on TCE declined faster than that of GDP, suggesting that decoupling TCE from economic growth should always be the top priority regardless of a country's development level. Policy-wise, for countries where GDP is the primary driver of TCE, measures to reduce transportation activities include industrial upgrading, coordinated planning, and accessibility promotion. For countries where energy intensity is the primary driver of TCE, measures to improve transportation efficiency consist of technology adoption, regulation/pricing, and habit improvement.

디지털 의료기기의 등장에 따른 법적 문제와 법제 개선에 관한 연구

This study aims to review and improve the current legal issues related to the emergence of Digital Therapeutics. First, we reviewed the scope of the Game Industry Promotion Act (Game Industry Act) and what regulations are made under the Game Industry Act. In particular, the scope of application of the Game Industry Act is the same as whether or not a game falls under Article 2(1) of the Game Industry Act, and we found that the concept of a game is used in a broad sense both in literature and in practice. In other words, there have been precedents in which content in the field of education and video, which has not traditionally been considered a game, that uses VR technology or has a game nature, has been considered a game under the Game Industry Act. In addition, after reviewing the concept of Digital Therapeutics and examining related laws such as the Digital Medical Products Act, we found that some of the Digital Therapeutics use VR technology or take the form of a game, so there is room for them to fall under the Game Industry Act, but there is no discussion of game products in the legal discussions related to Digital Therapeutics. Therefore, in order to ensure that Digital Therapeutics with game characteristics are appropriately regulated in the Korean legal system, it is necessary to introduce a new concept of 'Digital Therapeutics game product' in the Digital Medical Products Act, establish a classification system that considers the characteristics of both Digital Therapeutics and game products, and provide special provisions. In addition, it suggests that improvements should be made to medical treatment benefits and telemedicine related to digital medical device games.

Capacity optimization and multimode operation analysis of electric vehicle charging system powered by grid, solar and geothermal energy

The high penetration of renewable energy in electric vehicle (EV) charging system is critical for the EV industrial promotion and carbon neutrality in transportation area. In this study, an EV charging station powered by grid, solar photovoltaic (PV) and geothermal energy from abandoned wells for a highway is proposed together with novel multi-mode operation strategies. Based on the EV charging loads predicted from highway traffic information, NSGA-II algorithm is used for capacity optimization, and two control strategies (i.e., geothermal power multistep output regulation, and geothermal power multistep output + flexible control in charging load regulation) are proposed to achieve the multimode operation. The matching relationship between energy supply and charging load under the proposed and conventional control strategies are compared. The results show that the proposed control strategies allow the optimization of geothermal operation by avoiding the frequent ON/OFF of geothermal power block and increasing its full-generation duration. As a result, the corresponding shares of renewable energy can have 14.8 % and 20.2 % increases, and operation costs are reduced by 14.4 % and 20.9 %, respectively. This study helps to promote the rational configuration of renewable energy-powered charging system for EV and enhance the low-carbon transportation infrastructure.
