The economic exchanges have become increasingly frequent between China and Korea and the average annual growth rate of the total trade volume has increased by 30% since the establishment of diplomatic relations between the two countries. With the rapid economic growth and industrial upgrading of China, there are changes in the investment of Korea in China and domestic demand of China, and the trade structure of Sino- Korea has changed a lot in recent years. The changes have mainly manifested in the following aspects, including the increased proportion of high-tech products, raw materials and the intra-industry trade, the decreased proportion of consumer goods, the inter-industry trade and the trade deficit of China. With the development of the situation of international economy, the scale of Korea and China trade will continue to expand and the structure of Korea and China trade will also keep on changing in the long run.

In recent years, virtual reality (VR) technology has been widely used in many industrial fields, especially in the fields of medical treatment, games, film and television, to improve the interaction between medical teaching and practical treatment. On the gaming side, the production of virtual reality gaming screens and scenes became increasingly popular, greatly expanding the form of the visual experience. But VR is no longer confined to the health care, education and entertainment industries. During this time, the news media industry has also begun to integrate virtual reality into interviews and user interactions. This study aims to analyze the development of VR technology from the perspectives of immersive VR news experience, real reporting, and prospects, and analyze and think about the interactive participation of media users, the transformation of traditional media, and the upgrading of practitioners' roles.

China and Korea are good neighbors and partners. Since the establishment of diplomatic relations in 1992, the two countries have made promising achievements in political, economic, and humanistic exchanges for over three decades. In particular, bilateral economic and trade relations have yielded fruitful results, attracting worldwide attention. There are also unavoidable issues in the rapid development of bilateral trade and economic cooperation. And it is of great significance to look back on the past and look forward to the future on the 30th anniversary of the establishment of diplomatic ties between China and the Korea. With the upgrading of China's industrial structure and technological level, the bilateral trade relationship has gradually shifted from a complementary one to a competitive one. It is essential that both countries keep in mind the mutually beneficial nature of their relationship and make due contribution to the development of the Northeast Asian region and the world economy.

This research is to investigate the effect of the improvement of investment environments with investment incentive on Korean national economy by looking into the foreign investment support system in Korea. To this end, first research model was set up based on our literary study and case study was conducted on 150 foreign companies that were located in industrial complex for foreign companies, received the tax benefit and government subsidization. And it was found that even though the foreign companies were contributing to the national economy in general such as in the area of production, export, employment, development of technology, there was no significant contributory difference between the investment incentive beneficiary and non-beneficiary foreign companies. Therefore it deemed reasonable to reconsider the way Korean government supports foreign companies in Korea and to reinforce foreign companies' relevance to national policy agenda with additional incentives to foreign companies located in comparatively less developed areas. As a way to promote foreign investment, promotion of investment infra such as improvement of follow-up services, openness to foreign investment, industrial deregulations in capital area, revitalization of free economic zone, efficient system to promote foreign investment and the reinforcement of public relations were considered necessary, especially the upgrading of economic structure and the integrated management of domestic and foreign investors deemed necessary for the optimal distribution of the industries.

Electropulsegraphy is a medical device that was invented by an orient medical physician and a few engineers to help the physicians to diagnose patients in more systematic way by analyzing waveforms generated from the device. Data generated form the device has been collected for over several decades, and undergoes functional upgrades today. The device generates 33 waveforms that reflect the states of patients. As one of those upgrading efforts, we strive to develop an intelligent algorithm that makes the diagnostic process automatically, which was previously done manually for a long period of time. The logistic regression algorithm is used for our classification problems, which is one of those well-known algorithms for various classification problems such as character recognition systems. Out of the 33 waveforms, we only use 5 waveform data (Type1 toType5) as training data sets to estimate the parameters of the logistic regression. And the parameters are used to classify waveform inputs chosen at random.

Semiconductor logistics systems are facing difficulties in increasing production as production processes become more complicated due to the upgrading of fine processes. Therefore, the purpose of the research is to design predictive models that can predict traffic during the pre-planning stage, identify the risk zones that occur during the production process, and prevent them in advance. As a solution, we build FABs using automode simulation to collect data. Then, the traffic prediction model of the areas of interest is constructed using deep learning techniques (keras - multistory conceptron structure). The design of the predictive model gave an estimate of the traffic in the area of interest with an accuracy of about 87%. The expected effect can be used as an indicator for making decisions by proactively identifying congestion risk areas during the Fab Design or Factory Expansion Planning stage, as the maximum traffic per section is predicted.
