The Chinese ancient accounts of timing observations of 48 lunar eclipses and the secular variation of the Earth's spin speed are discussed. A series of ΔT expressing the secular deceleration of the Earth's rotation was obtained. The average increase rate of length of the day is about 1.5 milliseconds per century.

The purpose of this thesis paper is to explore the selection of quality cost management dimension indicators, the mechanism of quality cost management on enterprise performance, the size of the impact of each component of quality cost management on enterprise performance, in order to improve the quality management cost management theory. On this basis to minimise the loss cost and achieve optimal enterprise performance. The paper analyses the impact of quality cost management on enterprise performance by designing questionnaires, collecting data through surveys and using statistical methods. The relevant theories of quality cost management and enterprise performance is compared, and the correlation between qualities cost management and enterprise performance is explored by means of a questionnaire. This paper also explores the extent to which each component of quality cost management affects firm performance, which in turn enriches the relevant theories of quality cost management. The results of this study indicate that quality cost management has an important impact on enterprise performance, and that recognising the relationship between quality cost management and enterprise performance, identifying scientific management methods, and continuously improving quality cost management are important means of enhancing enterprise competitiveness. It is expected that it can provide some references for enterprises to carry out quality cost management effectively.

Cross-cultural adaptation is a social behavior that occurs when individuals enter a foreign cultural environment. Cross-cultural adapters learn the moral norms, language customs, and other aspects of the host culture, gradually adapting to and accepting it. They integrate their inherent beliefs, thoughts, emotions, and behavioral patterns with the host culture, forming a diverse multicultural background. Since humans have engaged in cross-geographical interactions, cross-cultural adaptation has existed worldwide. With the development of science and technology and the advent of global economic integration, the world has become a global village. Nowadays, more and more people travel far from their hometowns to study, work, and engage in activities in foreign countries. Cross-cultural encounters bring novelty, mystery, and a sense of pressure, as living in a different culture means making specific changes in lifestyle and thought patterns. This change can be stressful, and not everyone can overcome it to adapt to life in a foreign country successfully. Therefore, cross-cultural adaptation is one of the most essential areas in today’s cross-cultural education. This study explores the internal and external factors that affect the cross-cultural adaptation of international students in South Korea and proposes relevant strategies to improve their cross-cultural adaptation.

Under the background of economic globalization, the trade between countries in the world is increasing rapidly. Under the rules of WTO, the tariff rate of trade barriers is decreasing, but on the other hand, nontariff barriers are increasing. especially Compared with tariff barriers, green trade barriers have a greater impact on agricultural trade. Therefore, the negative impact of green trade barriers on agricultural products trade is a problem worthy of attention and urgent response in the future agricultural products trade between China and South Korea. Firstly, this paper analyzes the meaning and characteristics of green trade barriers, introduces the current situation of agricultural products trade between China and South China, analyzes the influence of Korean trade barriers on’s agricultural products export trade, and on this basis, forms countermeasures to promote Chinese agricultural products export to South Korea. The research of this paper has certain guiding significance for promoting Chinese agricultural export trade to South Korea.

Findings – The development of China-Korea FTA has an obvious role in promoting the trade between the two countries and helps to promote the economic development of both countries. Suggestions include: China and Korea should further expand the depth of bilateral trade cooperation; use the China-Korea FTA to realize the upgrading of industrial structure of both countries; use the China-Korea FTA to expand bilateral cooperation in foreign investment services.

The purpose of this study is to analyze the efficiency of research institutes of futures companies, and to promote the development of futures market and real economy. This study employs DEA-solver software to conduct super-efficiency data envelopment analysis (SE-DEA), and also selects 40 representative futures research institutes in China as decision-making units (DMUs). For data of input and output indicators, we collect from the China Futures Association, Futures Daily, Hexun.com and Webstock.com respectively, and the time duration is the 103 trading days between from October 2019 to February 2020. Then the indicator for the strategy accuracy rate is calculated separately by analyzing the strategies published by each DMUs in public media. In conclusions, most institutes have excessive investment in human resources, and also have insufficient strategy accuracy rate and insufficient published research reports. The findings of this study suggest that Chinese futures companies need to improve the efficiency of research institutes, and better meet the demand of the financial market. In fact, the analysis of the efficiency of the futures company research institute has not been found in the literature worldwide, Application of DEA model in efficiency analysis of securities and futures research institutions and establishment of indicators are the innovations of this paper.

This research investigates the consequences of the increase in corporate use of short-term debt in China over the past decades. Using a sample of Chinese firms from 2007 to 2018, we empirically explore the effect of corporate use of short-term debt for long-term investment (SFLI) on audit pricing. We first examine the relationship between SFLI and audit pricing for different groups of firms. Then, we investigate the role of the increase in short-term debt in alleviating principal-agent conflicts and reducing agency costs. We have four primary empirical findings. First, auditors tend to charge SFLI clients higher fees. Second, the negative relationship between SFLI and audit fee is found in private firms, firms audited by Chinese domestic auditors, and firms with higher information asymmetry. Third, the time auditors spent on SFLI clients is significantly more than that spent on non-SFLI clients, suggesting that the decrease in audit fee is not due to the decrease in cost. Fourth, SFLI significantly reduces the agency costs of the firm, which auditors regard as a low risk signal and grant an audit fee discount. Our findings suggest that the decrease in debt maturity, not only influences managerial behaviors, but also influences auditors’ risk assessment and pricing decisions.

Purpose: Many studies show that promoting the development of trade facilitation has a positive role in stimulating the country's foreign trade.
