The purpose of this study is to analyze the efficiency of budget utilization of science and technology by the Chinese autonomous province and to present the direction of improvement. Data were obtained from the 2013-2017 statistical yearbook of higher education published by the Ministry of Education of China, and efficiency was analyzed using the malmquist analysis method. The analysis found that the low technological progress caused changes in the productivity MPI index, and that cities affected by technological efficiency needed to improve internal factors such as internal coordination and restructuring of universities in the region to increase efficiency. And it was found that areas affected by technological change needed proper response to external factors such as government policy, economic environment, social environment or technological development. This study is meaningful in that it presented reference data in enhancing efficiency of budget utilization of science and technology by autonomy of China, and it is necessary to establish strategies and study essential factors to increase efficiency of inefficient areas in the future.

The increase in the number of ships entering and leaving the port and the creation of various cargo volumes can promote local economy and lead to regional development, attracting businesses, and influx of local residents. The port area of Dangjin consists of the limited cargo and most private docks, making it increasingly weak in meeting the local economic development and the expectations of local residents. Therefore, in order to promote regional development and revitalize the local economy, and to reduce the sense of alienation of local residents, it is necessary to make it easier to access and water to ports through the development of all areas of Eumseompo-gu, and to make active changes in the marine and port logistics environment. As seen through various cases of port development at home and abroad and the redevelopment of the ports at Gohyeon Port in Geoje, Dangjin Port should be able to quickly demonstrate the development of the Dangjin Port area and improve the quality of life for the residents of the metropolitan area. This is the time when the government's drive is highly requested.

This study focuses on the path planning algorithm for large-scale autonomous delivery using drones and robots in urban environments. When generating delivery routes in urban environments, it is essential that avoid obstacles such as buildings, parking lots, or any other obstacles that could cause property damage. A commonly used method for obstacle avoidance is the grid-based A* algorithm. However, in large-scale urban environments, it is not feasible to set the resolution of the grid too high. If the grid cells are not sufficiently small during path planning, inefficient paths might be generated when avoiding obstacles, and smaller obstacles might be overlooked. To solve these issues, this study proposes a method that initially creates a low-resolution wide-area grid and then progressively reduces the grid cell size in areas containing registered obstacles to maintain real-time efficiency in generating paths. To implement this, obstacles in the operational area must first be registered on the map. When obstacle information is updated, the cells containing obstacles are processed as a primary subdivision, and cells closer to the obstacles are processed as a secondary subdivision. This approach is validated in a simulation environment and compared with the previous research according to the computing time and the path distance.

With the recent increasing interest in sustainability management, the latest environmental report tends to be substituted by the expanded sustainability management report. In this work, I would like to introduce the management pattern of a global enterprise that values environmental soundness (environmental friendly) and implements eco-friendly measures. The enterprise chosen in this study is FedEx. In this article, FedEx case is presented how companies can adopt environmental friendly management in their businesses. FedEx has maintained an eco-friendly management since the introduction of the company's eco-friendly transport trucks in 2003, following its development in 2000. In 2005, it installed a solar power plant that can supply up to 80% of the electricity consumed by Oakland Logistics Center in California, USA. FedEx has published the "Global Enterprise Citizenship Report," which contains its business developments in 2009. FedEx has worked hard to minimize the influence caused by packaging of goods to the environment and appealed to customers to use recycled products as much as they can. FedEx also encourages customers to use packaging materials efficiently. A considerable amount of energy has been expended in the eco-friendly programs of FedEx. Although thousands of FedEx vehicles and aircraft operate daily with using large amounts of electricity and fuel, FedEx focuses on energy savings and global environment protection.

In this study, we analyzed the working environment of wholesale market distribution workers and suggested policy directions for the maintenance, operation, and development of sustainable wholesale market functions in response to changes in agricultural product distribution environment and working environment. The results of the analysis showed that there is a large gap in the working environment between wholesale corporation workers and middle wholesalers, and overall, the level of satisfaction with the working environment was low. In order to maintain sustainable wholesale market functions in the future, various policies and support should be established to improve the working environment of wholesale market distribution workers. The directions are as follows. First, wholesale market corporations should expand support for improving working environments by introducing systems such as rotational work by investing a portion of their profits in expanding manpower in response to changes in agricultural product distribution environment and working environment. Some Corporation of Garak-dong Wholesale Market is making great efforts to improve the working environment by introducing a rotational work system by expanding the workforce of auctioneers and providing a practical 5-day work week. In addition, in the case of wholesalers, it is expected that most of them will have difficulty in increasing their workforce as they are small businesses. However, it is judged that consolidation of businesses among wholesalers can be an alternative to increasing their workforce through expanding their management scale.

Recently, import and export companies have been using T/T remittance and Surrender B/L more frequently than L/C when selecting the process and method of trade payment settlement. The new trade and logistics environment is thriving in the era of the Fourth Industrial Revolution (4IR). Document-based trade transactions are undergoing a digitalization as bills of lading or smart contracts are being developed. The purpose of this study is to verify whether exporters choose export payment types based on negotiating factors. In addition, we would like to discuss the application of the characteristics of the new trade and logistics environment. Data for analysis was collected through surveys. The collection method consisted of direct visits to the company, e-mail, fax, and online surveys. The survey distribution period is from February 1, 2023, to April 30, 2023. The questionnaire was distributed in 2,000 copies, and 447 copies were collected. The final 336 copies were used for analysis, excluding 111 copies that were deemed inappropriate for the purpose of this study. The results of the study are shown below. First, among the negotiating factors, the product differentiation of exporters did not significantly affect the selection of export payment types. Second, among the negotiating factors, the greater the purchasing advantage recognized by exporters, the higher the possibility of using the post-transfer method. In addition to analyzing the results, this study suggests that exporters should consider adopting new payment methods, such as blockchain technology-based bills of lading and trade finance platforms, to adapt to the characteristics of the evolving trade and logistics environment. Therefore, exporters should continue to show interest in initiatives aimed at digitizing trade documents as a response to the challenges posed by bills of lading. In future studies, it is necessary to address the lack of social awareness in Korea by conducting advanced research abroad.

Recently, the change of shipping and port environment has required the new strategy from the liners, terminal operators, ports. The ports of call in the North American and European line also has changed as the Chinese ports made rapid advance. This seems to result from the fact that the trend of the container transportation by sea has developed the traditional concept, called port-to-port system that directly links between a port and another port into the network with complicated hierarchical structure reflecting costs, efficiency, and strategy of the Mega Carrier. This paper suggests the factors for Busan port to become the hub port of northeast Asia by analyzing the change of the liners' strategy along the change of the shipping and port environment, the global management of the operator of container port, and the amount of containers flowing in the northeast Asia.
