Since China put forward the Belt and Road Initiative in 2013, China has actively worked with the Initiative to revitalize relevant regional resources and encourage developing countries to participate in global social governance from a global macro strategic perspective. It should be noted that the initiative has promoted connectivity and exchanges among countries by promoting border infrastructure construction. This strategic direction is in line with Indonesia’s “global marine fulcrum” plan. Moreover, the development of infrastructure construction in Indonesia lags behind. These factors have provided more opportunities and development space for The cooperation between China and Indonesia in the field of infrastructure construction, and the economic cooperation is getting closer and deeper. This paper, based on the relevant data collected in Indonesia from 2003 to 2018, verifies the impact of China’s direct investment on Indonesia’s economic growth by using the method of mediation effect verification and explores the impact of specific approaches.The results show that China’s direct investment in Indonesia can promote local infrastructure construction and promote Indonesia’s economic growth. The two countries proposed future cooperation in areas such as electricity, Internet communication and education infrastructure

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.

Korean Wave is a very popular cultural phenomenon in China in the 21st century. Under the background of modern society, it exports various Korean cultural products to China through mass communication, and develops rapidly in China through Korean movies, pop music, variety show, food clothing and other forms. The input of these cultural products not only affects the Chinese public, but also profoundly affects contemporary Chinese college students. They have positive effects such as changing their way of life, improving their international perspective, and promoting personality shaping, but also have negative effects such as the worship of money in consumption concepts, the popularity of value orientations, and the shaking of cultural confidence. College students are the backbone of national construction. In the face of the coming Korean Wave culture, the family, school and society should correctly guide contemporary college students to treat rationally. While absorbing essence, they should adhere to cultural self-confidence and establish correct personal values.

In this study, impact of the COVID-19 outbreak on PM2.5 mass and its five chemical components (NH4 +, NO3 -, SO4 2-, OC, EC) in Busan was evaluated, and compared with that of Seoul. The study period over the recent three years was sub-divided into two periods: Pre-COVID (2018~2019) and COVID (2020) periods, and the differences in observed annual and monthly variations between the two periods were explored here. The results indicated that annual mean PM2.5 mass concentrations decreased during the COVID period by 16% in Seoul and 29% in Busan, and the satellite-observed annual average of aerosol optical depth (AOD) over the Korean Peninsula also decreased by approximately more than 10% compared with that of the Pre-COVID period. All of the five chemical components decreased but no particular changes were found in their fractions occupied during the COVID period. However, over the Lock-down period (2020-March), the sulfate fraction decreased in Seoul, mostly reflecting the recent Chinese trends of aerosol characteristics, whereas the nitrate fraction considerably decreased in Busan, which was attributable to the local emission changes and their variabilities in Busan. Other meteorological characteristics such as higher frequencies of easterly winds in the Busan area during the COVID period were also discussed in comparison with those in the Seoul area.

Over the past 40 years of reform and opening up, China’s use of foreign direct investment (FDI) has had all-round, multilevel, and wide-ranging implications. In the early stages of reform and opening up to attract foreign capital inflow to the country, relatively strong tax-preferential policies were implemented. The main purpose of this study is to analyze the impacts of FDI and foreign-related taxation on China’s total tax revenues as well as explore the direct and indirect effects of FDI on China’s taxation over the last 40 years to compare the contributions of FDI in different regions of China. Based on the results, some suggestions are proposed for the adjustment of China’s policies to promote foreign capital inflow in the future; moreover, suggestions are also provided for using foreign capital to stabilize employment and foreign trade, while promoting taxation.

With the implementation of the internationalization strategy of traditional Chinese medicine (hereinafter referred to as “TCM”) and the increasing recognition of TCM in the world, the export trade of traditional Chinese medicinal materials has shown an overall positive trend. With the rapid development of the global economy, people's pursuit of wealth has gradually accelerated, and at the same time, they have paid much more attention to pollution-free and health and green environmental protection than before. A new measure to protect the domestic ecological environment has emerged internationally - green trade barriers. Based on the analysis of the general situation of green trade barriers and the status quo of the industry, this paper expounds the performance and reality of the green trade barriers encountered in China’s export of Chinese herbal medicines, and then provides four countermeasures: firstly, spread and promote screening and classification standards of regions and material origins for medicines; secondly, resolutely promote industrial production standards to ensure the quality of traditional Chinese medicinal products; thirdly, accelerate the cultivation of international TCM trade talents to help better predicting and responding to the green trade barriers; and lastly, strengthen the overall management of the traditional Chinese medicine industry.

In this study, the prediction technology of Hydrological Quantitative Precipitation Forecast (HQPF) was improved by optimizing the weather predictors used as input data for machine learning. Results comparison was conducted using bias and Root Mean Square Error (RMSE), which are predictive accuracy verification indicators, based on the heavy rain case on August 21, 2021. By comparing the rainfall simulated using the improved HQPF and the observed accumulated rainfall, it was revealed that all HQPFs (conventional HQPF and improved HQPF 1 and HQPF 2) showed a decrease in rainfall as the lead time increased for the entire grid region. Hence, the difference from the observed rainfall increased. In the accumulated rainfall evaluation due to the reduction of input factors, compared to the existing HQPF, improved HQPF 1 and 2 predicted a larger accumulated rainfall. Furthermore, HQPF 2 used the lowest number of input factors and simulated more accumulated rainfall than that projected by conventional HQPF and HQPF 1. By improving the performance of conventional machine learning despite using lesser variables, the preprocessing period and model execution time can be reduced, thereby contributing to model optimization. As an additional advanced method of HQPF 1 and 2 mentioned above, a simulated analysis of the Local ENsemble prediction System (LENS) ensemble member and low pressure, one of the observed meteorological factors, was analyzed. Based on the results of this study, if we select for the positively performing ensemble members based on the heavy rain characteristics of Korea or apply additional weights differently for each ensemble member, the prediction accuracy is expected to increase.

The study was aimed to investigate the correlation between tidal effects and fog occurrence in Incheon and Mokpo, which are located in the middle and southern coasts of the West Sea of Korea, respectively. The investigation used meteorological data obtained from the automated synoptic observing systems and automatic weather stations and ocean data from tide stations from 2010 to 2019. Fog occurrence frequency was highest at high tide (Incheon, 41%; Mokpo, 45%). During fog event days at high tide, the dew-point depression was low (Incheon, 0.5 ℃; Mokpo, 0.4 ℃) and the relative humidity was high (Incheon, 97%; Mokpo, 9 8%). The w ind speed w as 2 . 4 m/s in I ncheon a nd 2 .0 m/s in M okpo, a nd t he m ain wind d irections w ere west-southwesterly from Incheon and southwesterly from Mokpo. In the fog case study, tidal flats were covered with water before and after the fog started. During the fog period, both stations experienced negative air-sea temperature differences, low dew-point depression, and high relative humidity were maintained, with weak winds forming from the tidal flats to the shore.

The purpose of this study is to extract climate element affecting coffee yield by growth period using data of production and cultivation area of coffee and climate data for 2000-2018. During the analysis period, the production of coffee in Vietnam has been consistently increasing, but Ðăk Lăk in the Central Highlands, the main cultivation area for coffee production, has recently stagnated in the trend of increasing yield. The yield of Lâm Đồng, located in the relatively highlands of the Central Highlands, is steadily increasing. Coffee yields of Ðăk Lăk is negatively correlated with the temperature during flowering period, and is also significantly negatively correlated with the maximum temperature and precipitation during the late growing period. On the other hand, Lâm Đồng, located at a relatively high altitude, has a positive correlation with temperature during the late growing period. It is analyzed that the lower the altitude, the higher the temperature, the lower the coffee productivity due to the high temperature appearance, and the lower the low temperature appearance in the high altitude region.

While Shandong Province is the largest historical and cultural and the first agricultural province in China, in recent years, due to the accelerated urbanization and modernization process, the conflict between traditional culture and modern civilization has had a serious impact on rural culture, and the ancient architecture among the villages in Shandong has also caused certain damage. These ancient buildings scattered in various villages in Shandong are important historical and cultural resources, the embodiment of Shandong traditional culture, and have an important role in the revitalization of rural culture and the enhancement of rural cohesion. However, research on the subsequent survey, conservation and restoration, and tourism development of ancient buildings in Shandong has lagged behind, and the role of these buildings in the inheritance of traditional Shandong traditional culture has not been given due attention, and their role in the construction of rural culture in the new era of Shandong has been seriously neglected. Tourism utilization is generally considered to be the preferred way to solve the conservation problems of ancient buildings. This study argues that the cultural revitalization of rural culture can be driven by the tourism and cultural industry of ancient buildings, and it can also provide a strong and sustainable power source for the rural revitalization strategy of the whole Shandong Province.

Jeju Special Self-Governing Province has implemented a self-governing environmental impact assessment system (Jeju-EIAS) in recognition of its autonomy. In this study, the institutional features of Jeju-EIAS were examined by analyzing the development projects whose consultation under Jeju-EIAS were completed from 1994 to 2019. The consultation procedure of Jeju-EIAS, such as the actual operation of Review Committee for Environmental Impact Assessment (EIA), the consent of the provincial council, and the regular follow-up activities for the implementation of EIA consultations, has been implemented differently from those of other metropolitan cities and provinces. Under Jeju-EIAS, types of development projects subject to consultation on EIA also take into account local conditions, and include the construction of aquarium basin and building. In addition, provisions concerning the scale of development projects is strengthened above the Korean Environmental Impact Assessment Act (EIA Act).

This study was initiated to isolate the microorganisms removing phosphorus (P) from domestic sewage and to investigate the effects of environmental factors on the growth and P removal of the isolated bacteria. Microorganisms isolated from the sewage were identified as Chryseobacterium sp., Stenotrophomonas maltophilia, and Bacillus licheniformis. Among them, Bacillus licheniformis was selected as the P removal microorganism. The environmental factors considered in this study included initial phosphorus concentration, temperature, pH, and carbon source. At initial P concentrations of 10, 20, and 30 mg/L, the P removal efficiencies were 100.0%, 84.0%, and 16.5%, respectively. At 20°C, 30°C, and 40°C, the P removal efficiencies were 0%, 75.8%, and 60.6%, respectively. The removal efficiencies of phosphorus according to pH were 1.6%, 91.7%, and 51.1% at pH 5, pH 7, and pH 9, respectively. Using glucose, acetate, and glucose + acetate as carbon sources yielded P removal efficiencies of 80.9%, 33.6%, and 54.1%, respectively. Therefore, the results from the study demonstrated that the P removal efficiencies of Bacillus licheniformis were the highest when the initial P concentration, temperature, pH, and carbon source were 10 mg/L, 30°C, 7, and glucose, respectively.
