China's 'One Belt and One Load' is a national development strategy that aims to develop China and Eurasian Economic Area into a single economic Area by overland and sea routes. Thus, China's 'One Belt and One Load' construction will be a new engine for China and global economic development. At the same time, expected to have a significant impact on the international economic order and the enhancement the status of the Chinese economy. First of all, 'One Belt and One Load' will contribute to China's social stability by reducing the development gap between the East and West regions to some extent, as well as solving the problems of overcapacity and overproduction in China. Moreover, with a stable supply of energy resources, it will also contribute to the stable development of the Chinese economy. China's 'One Belt and One Load' will also enhance China's status by enhancing the level of Chinese influence and RMB in the international economy, in addition to the economic development of China and 'One Belt and One Load' consecutive countries. In particular, it will weaken the influence of the US, which has dominated the hegemony in the international community. Therefore, Korea, which maintains close economic relations with China, needs to prepare for countermeasures by closely monitoring the change in China's status as a result of China's 'One Belt and One Load' construction.

China's 'One Belt and One Load' initiative is a mega-infrastructure project that connects China and the Eurasian Economies Area by overland and sea routes. Therefore, if it goes smoothly, It will be a new engine for economic development in China and the world, and It is expected to be a factor that will change the structure of the international economy. Especially, the Eurasian continent is likely to develop into the center of the global economy. But China's 'One Belt and One Load' initiative is not only macro and long-term, but also implies complexity, making it hard to be optimistic about development. China's 'One Belt and One Load' initiative is not only strongly promoted as a long-term national development strategy to be completed by 2049, but also strong economic complementarity between China and 'One Belt and One Load' consecutive countries. And many of the successive countries are expecting 'One Belt and One Load' construction. Therefore, there is no possibility at all. In particular, the possibility of development can not be completely ruled out, given the various policies of 'One Belt and One Load' currently being pursued by China. Even if it doesn't go smoothly, the process alone will have significant economic effects on China and neighboring countries, so it will be meaningful. With the help of information technology.

This study analyzed to strategy and structure of outward foreign direct investment(OFDI) by Chinese Enterprises in 'one belt, one load' countries along the line from the perspective of Dunning's OLI paradigm. Chinese enterprises' investment in 'one belt, one road' countries was largely promoted for two strategic purposes. One is an investment to secure energy resources due to the nature of resource holdings in 'one belt, one road' countries, and the other is a transfer investment to solve the problem of surplus facilities, a problem in China's domestic economy. Chinese enterprises' investments in these 'one belt, one road' countries is evaluated to have been made with Dunning's investment decision conditions in the OLI paradigm, namely, Ownership specific advantages, Location specific advantages, and Internalization specific advantages. only if there is a difference, investment country, investment method, and investment industry are different due to the structure of international relations, religious conflict and cultural heterogeneity, institutional investment environment of the region, and awareness of Chinese enterprises.

A V belt pulley is widely used in automotive industry. More than tow pulleys in one automobile are used, such items as crankshaft, water pump, air-con compressor and power steering pump. Although the shape and usage of pulleys are very simple, the design evaluation of a pulley design is difficult because the load conditions and the installation environment are complicated. So, we formulated the design evaluation for the V belt pulley by using CAE system, which enables to develop a design automation system. By using this system, an engineer can evaluate a pulley design easily without any painstaking effort, such as consideration of the complicated loads and CAE activities. Also the system helps to accumulate the design experience of a company, which guides the optimum design based on experience.

Ceramics are becoming one of the most important materials due to its good mechanical properties such as high strength, hardness, chemical safety, and high modulus of elasticity. Ceramics have been used widely as a material not only for construction, but also for vehicles, planes, and bones for the human body. Despite these advantages, ceramics have some limitations in actual use due to its brittle fracture characteristic. In order to develop ceramic belt in this study, the data regarding stiffness and strain is necessary. For this purpose, the sensitivities of maximum stress value and displacement are analyzed by applying the load change on ceramic belt with finite element method program.

Tensile and shrinkage characteristics of DTY, EDY and Macel were investigated experimentally. The drawn textured yarn(DTY) made by an existing belt type false twist and the elastic drawn textured yarn(EDY) made by non-torque false twist method modified from the belt type one. Macel was the yarn which had drawn and un-drawn arrangements. The tenacity of EDY had lower value than that of DTY. EDY had higher strethch than that of DTY. Especially Macel yarn had higher stretch than that of DTY compared with the same diameter of yarn. With time course behavior the tenacity and elongation of DTY and EDY had stabled tendency without variation. Before scouring Process, the wet and dry shrinkage patio of EDY load higher value than that of DTY. However, they decreased artier the process. At the same time, the stretch characteristic of EDY was significant as the diameter of yarn became higher.

Nowadays numerous research projects are being conducted in the field of electric motors. Non-modeling of flexible connections such as couplings and the belt-pulley do not show some real behaviors. With an increase in the number of connections and drive factors, these Non-modeled modes become more important. The coupling of two electric motors, instead of one motor, in submarine propeller force is an obvious example which shows that Non-modeled vibration modes caused by flexible connections can disturb controller operation and make undesirable vibrations in the submarine body. In this paper a dynamic model of flexible connections and a completed dynamic model of two different coupled electric models is presented. A robust controller for the completed model is also amended so that the two controlling targets of a desired speed adjustment and an appropriate load division between the two motors with sufficient accuracy are achieved.

In this study, product design and prototype manufacturing of a plastic water-pump pulley has been tried. The designed model is supposed to be made of 33 % glass reinforced resin of which the tensile strength is 180 MPa, and has 24 ribs on each side to increase its structural strength. Structural analysis under a static load of 300 kgf acting on both edges of the belt has been carried out using a commercial finite element code, MARC. The analysis result showed the maximum effective stress near a rib of designed model would be at most 35 MPa (less than 20% of the tensile strength), therefore, the plastic product would be sufficiently safe under that loading condition. On the basis of the structural analysis, a prototype of the designed model has been manufactured by using the fused deposition modelling (FDM) method which is one of the rapid prototyping (RP) methods, using ABS resin and support materials. The CAD data exported to the RP system in STL format was prepared by a commercial solid modeling software, SolidWorks. It has been proved that the plastic pulley can successfully replace the existing flow-formed steel product.

As post-harvest processes of onions are carried by a 20 kg-net package which results in high-cost and low-efficiency, especially, the insufficient drying and physical damage of onions after harvesting leads to a huge second loss in storage, we had developed a low-cost, high-efficiency post-harvest bulk handling machinery system by collecting onions on a farm using ton-bags, drying with forced air circulation, and sorting/packaging. The post-harvest bulk handling machinery system consisted of 6 devices, and this study designed an automatic feed hopper with a feeding rate control device, an inclined belt conveyor with a two-step chute, and an automatic pallet unloading device for feeding onions into the sorting/packing line. This study also analyzed the performance and control of the total system. The device had 1-ton handling capacity, but the operational condition was set to increase the capacity. The three-step filling method of pallet by the velocity control of the inclined belt conveyor was applied in the post-harvest bulk handling machinery system for the prevention of physical damage. If one worker was set to operate the total system, the time required to complete one palletized load was approximately 5 minutes and 5 seconds. The calculated daily handling capacity was approximately 94 tons, when the daily actual working time was 8 hours. When the developed system was applied to the managerial size of 2,000 ton, the processing cost per ton of the system was decreased by 19.5%, compared with the existing 20 kg-net package-based handling. The developed post-harvest bulk handling machinery system would be a good substitute for the rapid decline and aging of rural labor.
