Abstract

Background: Climate change is one of the most pressing global challenges, with significant consequences for ecosystems, economies, and human societies. International environmental law plays a critical role in shaping global efforts to mitigate climate change by establishing legal frameworks for cooperation and action. However, the effectiveness of international environmental law in addressing climate change remains a subject of debate, particularly concerning the implementation of mitigation strategies at the national and global levels. Objective: This study aims to analyze the role of international environmental law in climate change mitigation efforts, with a focus on the key legal instruments and agreements that shape global climate governance. The research seeks to evaluate the effectiveness of these legal frameworks in reducing greenhouse gas emissions and promoting sustainable environmental practices. Method: A qualitative research design was employed, using case studies, legal analysis, and interviews with environmental law experts, policymakers, and practitioners. The study examined major international agreements such as the Paris Agreement and the Kyoto Protocol to assess their impact on climate change mitigation efforts. Results: The findings indicate that while international environmental law has contributed to raising awareness and setting targets for climate change mitigation, the implementation of these efforts remains uneven, with many countries struggling to meet their commitments due to domestic challenges. Conclusion: The study concludes that international environmental law has been instrumental in global climate change efforts, but enhanced implementation mechanisms and greater international cooperation are necessary to achieve meaningful progress.

Abstract

Sentiment analysis in job descriptions plays a critical role in shaping employer branding and recruitment strategies. This study investigates the sentiment of job postings in the technology sector using NLP techniques, focusing on the emotional tone of descriptions across various job types, companies, and subcategories. The analysis reveals that positive sentiment predominates in job descriptions, with a clear trend towards using optimistic language to attract candidates. The findings show that Software Development positions tend to have the most positive tone, while roles such as IT Management exhibit a more balanced sentiment. Additionally, the use of inclusive language, such as "equal opportunity" and "years of experience", is prevalent in the descriptions, highlighting the growing importance of diversity and inclusivity in recruitment. Visualization tools like word clouds and trend analysis illustrate how sentiment shifts over time, with a noticeable increase in positive sentiment from 2020 onwards. The results underscore the potential of sentiment analysis and NLP in optimizing recruitment processes, aligning job descriptions with candidate expectations, and enhancing employer branding strategies.

Abstract

The coal feeder of our company's pulverizing system adopts JGC-30 weighing metering coal feeder. The raw coal in the raw coal hopper falls onto the coal feeder belt through the coal drop port by its own gravity. The existing design of high belt skirt on both sides is 40mm. A small amount of coal blocks falls off on both sides of the belt during the falling process. Due to the wind force of the coal feeder sealing wind and the operation of the belt, a small amount of coal blocks are scattered and stuck at the coal feeder weighing device. The inaccurate coal quantity measurement leads to large fluctuations in the coal feeding quantity of the pulverizing system, that will makes inducing abnormal vibration of the coal mill, insufficient coal powder output, large amount of slag discharge from the coal mill and other problems, which seriously affect the safe and stable operation of the pulverizing system. In this regard, the coal feeding belt was modified, and the skirts on both sides of the coal feeder were increased to 60mm. After the modification, it can be ensured that the raw coal does not fall from the skirts on both sides during the operation of the coal feeder, thereby solving the problem of inaccurate coal quantity measurement caused by coal blocks stuck in the weighing device. This study aims to address the problem by modifying the coal feeder belt, namely by increasing the skirt height on both sides of the belt from 40mm to 60mm. The method applied was to adjust the belt skirt design directly on the operating coal feeder, followed by operational testing to evaluate the effectiveness of the modification in preventing coal falling from the belt side. Results show that after increasing the height of the skirt belt, there is no more coal falling during coal feeder operation. Coal measurement became more accurate, which had a positive impact on coal feeding stability, reduced vibration in the coal mill, as well as increased fine coal output and reduced the amount of slag produced.
