On February 18, 2019, the Chinese government officially released the Outline of the Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area, which will lead the country in a new round of reform and opening-up. The Greater Bay Area will become a dynamic world-class city cluster, an international scientific and technological innovation center with global influence, an important support for the development of the "One Belt And One Road", a demonstration area for in-depth cooperation between the mainland and Hong Kong and Macao, and a high-quality living area for living, working and traveling. Non-Pearl River Delta(Non-PRD) cities in Guangdong Province are adjacent to the Guangdong-Hong Kong-Macao Greater Bay Area, so it is of practical significance to promote the high-quality development of urban tourism from an international perspective. Based on the panel data released in Guangdong Yearbook 2019, this paper uses the envelopment data analysis (DEA) method to explore ways to promote the high-quality tourism development of Non-PRD cities in Guangdong Province based on the perspective of international development.

In the last several decades, and especially since the Chinese launching of the Belt and Road (BRI) initiative in 2013, the Chinese presence in Central Asia has intensified. Russia and Chinese leaders deny that there is any conflict of interests between them, while the standard narrative has been that the two states adhere to a functional division of tasks in which China concentrates on economic activity while Russia acts as the security guarantor for the region. This article argues that the professed equanimity between the Russian and Chinese leaderships masks the emergence of widening cracks in their relationship with regard to Central Asia. The convenient narrative of a functional division of tasks between the two states is called into question by China's increasingly active presence in the military and security sector in the region, but China's influence is growing throughout the Central Asian economic, political, and social order. China's movement into Central Asia challenges Russia's claim to act as an equal partner of China, as well as its pretensions to regional hegemony. This development reflects the widening disparity between the two states with respect to their power capabilities but it also exposes the interactions between Russia and China in Central Asia as the most vulnerable aspect of their relationship. In Central Asia, a defensive Russia encounters an ascendant China.

With WTO system starting since 1995, the international trade business has been getting more competitive and fairer especially with the agreement on subsidies and countervailing measures. The export credit insurance, as the only institution of supporting export business under WTO system, is getting more significant in major economies as an indirect means to support export business. In China, SINOSURE has been monopolizing its export credit insurance market for a long time. Since January 2013, however, the Chinese government permitted several commercial insurers to compete in the market and they include PICC, PING AN, CPIC, China Re. This study is to discuss how to improve the Chinese export credit insurance after analyzing performance of privatization of short-term credit insurance and real cases of success and failures. With the 'Go Global' and 'One Belt, One Road' policy of Chinese government, the role of export credit insurance is expected to be more significant. Thanks to the Korea-China FTA since December 2015, international trade between the two countries will be greater especially in finance and insurance area. Because Korean insurance industry is very much interested in getting into Chinese export credit insurance market, they need to study carefully the performance of privatization of Chinese short-term export credit insurance. For their policy decision makings the Korean authorities need to get lessons from the privatization of Chinese short-term export credit insurance business.

Tilt is a key indicator of structural safety. Real-time monitoring of tilt responses helps to evaluate structural condition, enable cost-effective maintenance, and enhance lifetime resilience. This paper presents a prototype wireless sensing system for structural tilt measurement. Long range (LoRa) technology is adopted by the sensing system to offer long-range wireless communication with low power consumption. The sensor integrates a gyroscope and an accelerometer as the sensing module. Although tilt can be estimated from the gyroscope or the accelerometer measurements, these estimates suffer from either drift issue or high noise. To address this challenging issue and obtain more reliable tilt results, two sensor fusion algorithms, the complementary filter and the Kalman filter, are investigated to fully exploit the advantages of both gyroscope and accelerometer measurements. Numerical simulation is carried out to validate and compare the sensor fusion algorithms. Laboratory experiment is conducted on a simply supported beam under moving vehicle load to further investigate the performance of the proposed wireless tilt sensing system.

Lao-native beef cattle are primarily Bos indicus, and most ruminant production in Laos is still dominated by small-scale or backyard producers that use traditional practices, resulting in low productivity. The cattle herd size in Laos has grown by an average of 5 percent per year from 1.52 million in 2010/11 to 1.81 million in 2014/15. In 2016, the Laos cattle population was 1.88 million head, with smallholder farmers representing 98% of production despite efforts by the Laos government to develop commercial-scale farms. There were 170 commercial cattle farms in 2016, with 56 percent in the Central region of Laos. Although, overall, ruminant meat production has tended to increase but with consumption at 7.29 kg/capita/yr in 2013, it remains insufficient to meet demand. Crop residues and agro-industrial by-products used in ruminant diets include rice straw, cassava pulp and wet brewers' grains as roughage, energy and protein sources, respectively. The Belt and Road Initiative proposed by China in 2013 will connect China closely with all countries in Southeast Asia. This initiative will change landlocked Laos to land linked for investors who will benefit from convenient transport at a lower cost, promoting agricultural production in Laos.

This paper describes the launching characteristics of a passenger car using a Push-Belt type Continuously Variable Transmission(CVT) which equipped a wet type multi-plate clutch asa starting device and a solid flywheel with a torsional damper for a torsional coupling device. To reduce the torsional vibration of the drive-line , some torsional coupling devices were used for the passenger car equipped CVT having the clutch as a starting device especially . In this study, we developed the computer simulation program to investigate the launching characteristics of a passenger car equipped CVT using the mathematical models of this system. For the mathematical models of the vehicle, the CVT, the we type multi-plate clutch and the torsional damper, we obtained the specification and the necessary data through the reverse engineering of those. For the verification of our analysis, we performed the test of prototype car with different throttle positions at road and dynamometer. The launching characteristics of a passenger car considered here an acceleration performance and an ascending performance.

한국은 지속적인 성장을 위해서는 러시아, 몽골, 유라시아 등의 북방 경제권에 진출하는 것이 역대정부의 일관된 정책이다. 북방경제는 에너지 수요가 많고 산업이 발달한 우리나라와 상호보완적 경제구조로 시너지 효과를 기대할 수 있다. 또한 러시아 신동방정책, 중국 일대일로, 몽골 초원의 길 이니셔티브 등 중국-러시아-몽골 경제회랑이 가속화되는 기회가 만들어지고 있다. 한국 정부는 역대 정부가 추진하였던 북방정책을 계승하고 그간 미진하였던 북한을 포함하여 경제협력과 평화구축이라는 목표를 달성시키기 위한 신북방정책을 추진하고 있다. 국제적인 경제협력을 위해서는 필연적인 운송이 수반되기에 육로보다 유리한 해상운송의 수요가 증가되기 때문에 이에 대한 대비가 무엇보다 필요하다. 해상운송의 결절점인 항만을 보유하고 있는 한국의 항만도시는 신북방정책에 대비한 준비가 필요하다. 본 연구에서는 서해안 시대의 서산 대산항을 장기적인 발전을 기획하면서 신북방정책에 맞추어 북한의 개방발전 방안을 고민하였다. 정부간 및 지방도시간의 국제협력이 요구되기 때문에 서산시의 전향적인 태도와 함께 항만운영체와 협력이 필요하다. 이러한 대응을 적극 이행한다면 현재 액체에너지화물 중심항만의 서산 대산항이 신북방정책의 거점이 될 수 있으며 한반도에서는 서산 대산항이 명실상부한 서해안평화경제 허브로서 입지를 다지는 기회가 될 것이다.

The arbitration system has many advantages, including resilience, speed, ease of approval, and enforcement of foreign arbitration in international disputes, and it plays an important role in today's international business. As the world's economic activities increase, China's trade disputes are intensifying. In 2017, China emphasized the international cooperation and commercial expansion of foreign investment at "One Belt, One Road." Therefore, it is expected that international business will become more active, with the issue of how to recognize and enforce the foreign arbitration awards in China becoming highly important. In addition, South Korea and China maintained deep trade relations after establishing diplomatic relations in 1992 and concluding the Korea-China Free Trade Agreement, which will inevitably increase trade disputes. As far as South Korea is concerned, China is South Korea's largest trading partner, so it is important for South Korea to analyze how foreign arbitration awards are recognized and enforced in China. China's accession to the New York Convention in 1987 was the beginning of the enforcement of foreign arbitrators. However, since China has begun to recognize and enforce foreign arbitrators relatively late, there are many problems in terms of recognizing and enforcing foreign arbitral awards in China. This study introduces the concept and scope of foreign arbitral awards, as well as the legal basis and procedures for recognizing and enforcing foreign arbitral awards, and examines relevant cases and the denial of recognition and enforcement of a foreign arbitration award. In the end, some issues and remedies for the recognition and enforcement of the foreign arbitral awards system in China were concluded.
