Hang Gao 한국유통과학회 2017 KODISA ICBE (International Conference on Business Vol.2017 No.-

These days, the traffic related problems are very common things in our life. Under the background of green, low carbon, environmental protection and sustainable development, shared bicycles have achieved a rapid development period, with remarkable achievements and many problems. Shared bicycles have solved the problem of “the last mile of city traffic”. However, this new thing still faces many problems such as lack of supervision, industry competition, high cost, low operating efficiency and hidden danger. The development of internet technology and the popularization of mobile phones provide technical support for the promotion of shared bicycles. Shared bicycle users can realize the positioning of the no-pile bike with the help of GPS positioning technology, and realize convenient and quick payment by means of mobile payment technology. It is an important part of the supply-side structural reform in public transportation to solve the short distance transportation problem. In cities, buses and subway systems have been unable to solve the “last mile” problem of people traveling. Compared with the public bikes introduced by the government, the advantages of shared bikes in fast certification and no piling are obvious. In order to solve the problems above, we need the cooperation of core stakeholders such as government, industry, enterprises and users.

日本汉诗集《敕撰三集》用韵研究

Gao Hang 중국어문논역학회 2016 中國語文論譯叢刊 Vol.0 No.38

Chizhuansanji(敕撰三集) was a Chinese poems sylloge compiled in term of the command of the emperor of Japan, including Lingyunji(凌云集)、Wenhuaxiuliji(文华秀丽集) and Jingguoji(经国集). Based on Gangyun(广韵), the rhyme of pre-Tang poems in Chizhuansanji(敕撰三集) could be analyzed into 18 rhyme groups and the rhyme of modern style poems could be analyzed into 21 rhyme groups. That almost conformed to the principle of using alone and using with others in Guangyun(广韵).All the inconformity examples could be found in poems of Tang Dynasty. The rhyme system in Chizhuangsanji(敕撰三集) was more complex than Huaifengzao(怀风藻), because its pronunciation basis was “standard language of Tang Dynasty”. 《敕撰三集 칙찬삼집》은 일본천황이 칙명 하여, 편집하게 된 한시 총집이다. 이 총집은 《冲云集 름운집》,《文化秀丽集 문화수려집》,《经国集 경국집》으로 나뉘어있다. 본문은 《敕撰三集》중에 있는 한시를 고체시와 근체시로 나누었다. 《广韵 광운》에 의하면 고체시의 용운은 18운부로 볼 수 있고, 근체시의 용운은 21운부로 볼 수 있다. 《敕撰三集》에 한시의 용운은 대체적으로 《广韵》에 독립 용법과 결합 용법에 부합하지만 예외적인 현상도 있는데 그것은 당대 시의 용운 현상에 찾아볼 수 있다. 《敕撰三集》의 용운은 《怀风藻 부풍조》보다 복잡하며, 《敕撰三集》의 용운은 《切韵》 음계의 “汉音 한음”이다.

A Research on Countermeasures of Shared Bicycles in China

Gao HANG,Shuai SU 한국유통과학회 2018 KODISA ICBE (International Conference on Business Vol.2018 No.-

Under the background of green, low carbon, environmental protection and sustainable development, shared bicycles have achieved a rapid development period, with remarkable achievements and many problems. Shared bicycles have solved the problem of the last mile of city traffic . However, this new thing still faces many problems such as lack of supervision, industry competition, high cost, low operating efficiency and hidden danger. In order to solve the problems above, we need the cooperation of core stakeholders such as government, industry, enterprises and users.The Problems in the Development of Shared Bicycles in China: Firstly,Imperfect Market Supervision Mechanism. Under the constant promotion of internet + and innovation and entrepreneurship, a large number of new business models have emerged in sharing economy. Second, Blind Expansion with Hidden Dangers.Shared bike is favored by the capital market for its convenience and greening of the last mile of travel, and the financing rhythm and the amount of funds are constantly updated. Third, High Operating Costs.The manufacturing cost of shared bicycles is high. Fourth, Disordered Parking and Malicious Damage.The number of market launches of shared bicycles is large, and there is a need for large enough space to park. Fifth, Safety Performance Needs to be Strengthened No new thing, no industry can ignore safety.

Effect of Freeze-Thaw Cycles on Dynamic Characteristics of Undisturbed Silty Clay

Gao Hang Cui,Zhuo Cheng,Daili Zhang,Shuxian Ma,Zhiqiang Liu 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.9

We conducted dynamic triaxial tests of undisturbed soil samples under different control parameters using the Global Digital Systems (GDS) dynamic triaxial instrument. We investigated the dynamic and engineering characteristics of undisturbed soil under a freeze–thaw cycle. When the dynamic load amplitude and the number of freeze–thaw cycles were adjusted, we explored the cumulative plastic strain, dynamic elastic modulus, and dynamic strength of undisturbed soil, and we then proposed appropriate fitting formulae to compute the cumulative plastic strain, dynamic elastic modulus, and dynamic strength. The findings revealed that as the number of freeze–thaw cycles increased, the cumulative plastic strain grew, the dynamic strength progressively fell, and the dynamic elastic modulus dropped first, but then increased. The critical physical and dynamic features of soil changed dramatically during one to six freeze–thaw cycles. This study’s suggested formula for the average growth ratio can directly reflect the cumulative plastic strain fluctuation of soil throughout freeze–thaw cycles. The formula has a good fitting effect on undisturbed soil, according to the test findings, and the accumulative plastic strain, dynamic elastic modulus, and dynamic strength may be computed within a specified range. The findings of this study contribute to a better understanding of the effect of the freeze–thaw cycle on the dynamic characteristics of undisturbed silty clay, as well as a theoretical foundation for the design and construction of silty clay highway subgrade in seasonally frozen regions as well as the dynamic analysis of vehicle simulation in seasonally frozen regions.

Mechanical properties and neural network prediction of cement fly ash-enhanced roadbed soil in seasonal frozen zones under short-term curing

Gao Hang Cui,Zhuo Cheng,Fanyue Sun,Shuxian Ma,Zhiqiang Liu 대한토목학회 2024 KSCE Journal of Civil Engineering Vol.28 No.1

The freezing and thawing of roadbed soils in seasonal frozen zones can cause uneven settlement and other road problems, which puts road operation at risk. This paper focuses on the rapid construction of expressways and analyzes the effects of using fly ash and cement as modifiers on the physical properties and chemical composition of subgrade soil. The study found that cement admixtures can improve soil mechanical attributes and frost resistance, while also increasing the degree of fly ash hydration.And the freeze-thaw cycle process can enhance the mechanical characteristics of soils with higher cement admixture content. This is due to the development of hydrates in cement fly ash-enhanced soils during freeze?thaw cycles, resulting in a denser interior structure. The use of neural network prediction analysis showed that using ANN4-10-3 to forecast soil mechanical property parameters can produce superior results. Therefore, it is recommended to use cement fly ash-enhanced soil for roadbed construction in seasonal freezing areas, and neural network can be used to predict soil mechanical parameters.

Study on Changes and Development Trends of the Trade Structure between Korea and China

Gao, Hang 한국유통과학회 2012 Asian Journal of Business Environment (AJBE) Vol.2 No.1

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.

Study on Reasons and Prospect of Trade Deficit of Cultural Products between Korea and China

Gao Hang 한국유통과학회 2014 한국유통과학회 학술대회 논문집 Vol.2014 No.-

The friendly relationship between China and Korea develops in full scale, meanwhile the cooperation of the cultural trade has been strengthened continuously, providing enormous benefit for people from both countries. The trade deficit of cultural products between China and Korea is expanding gradually with rapid development of Korean cultural industry and increasing growth exporting to China. The main reasons of the trade deficit of cultural products are that the two countries are different in development of cultural industry and the support policies of cultural products export are disparate. Furthermore, as the strong historical and cultural similarity between these two countries, huge market demand on Korean cultural products in China is another important factor. China should learn some advanced experience from Korea, make policies helpful for development of cultural industry and export of cultural products, and increase cultural trade to compensate for the deficit.

Comparative Analysis on Cultural Trade Development between China and South Korea

Gao Hang 한국유통과학회 2015 KODISA ICBE (International Conference on Business Vol.2015 No.-

China South Korea are both located in East Asia and belong to the culture, so they have a very cultural In recent years, friendly relationship between China and South Korea has been developing rapidly. The deepening of the cultural and trade cooperation have brought tangible benefits to the people of the two countries. Cultural trade of South Korea has good momentum of development, and has continued to enhance the international competitiveness. In contrast, the development of cultural trade of Chian is relatively backward, and there is a large deficit in cultural trade. Through a comparative analysis on different areas of cultural trade between China and South Korea, it can be conformed that which are the shortcomings in the development of cultural trade of China. Thus, Government could formulate policies and measures to promote cultural industries and reduce the deficit.

Study on the Development of Sharing Economy in China under the Background of Mobile Internet

Hang Gao 한국유통과학회 2017 한국유통과학회 학술대회 논문집 Vol.2017 No.-

With the rapid development of mobile internet technology, sharing economy has infiltrated into many areas, such as traffic, accommodation, finance, catering, housekeeping services, agriculture. Sharing economy is a new business model which is based on the sharing of idle items or excess production capacity. The development of sharing economy is of great significance for China on industrial restructuring and sustained high growth. Sharing economy has a series of advantages which traditional business model has not. At present, sharing economy of China is still in the primary stage of development with many problems. The government should deeply understand the sharing economy, strengthen supervision and take safeguard measures to support its development to help China s economic transformation.

日本汉诗集《东瀛诗选》用韵研究

高航(Hang Gao),??娟(Li-juan Chen) 중국어문논역학회 2017 中國語文論譯叢刊 Vol.0 No.40

《동영시선》은 청나라 말기, 학자 유월이 일본에서 학자들의 협조 하에 편집하고 완성했다. 정전40권, 보유4권, 총 550명 시인의 5163편시를 엄선했다. 대부분 에도시대 시인의 작품이며 약간의 메이지 시대 작품도 있다. 운각자를 발췌한 것을 통해 예속된 부분을 병합했다. 《동영시선》은 고체시로 상성과 거성이 비교적 많이 사용되었고, 근체시는 평성을 주로 사용하였고, 운부가 《광운》과 같다. 《칙찬삼집》에서 중국 시인의 압운과 비교하면, 일본 시인은 창작시 운서 규칙을 준수할 뿐 아니라 당시 중국 어음의 발전 변화를 알 수 있다. DongYing Poetry Collection (东瀛诗选) was edited by Yu Yue, a scholar in late Qing Dynasty with the help of Japanese scholar. The main part consists of 40 volumes and the addendum 4 volumes. There are totally 5163 poems selected from 550 poets. Most of them were made by poets in the period of Jianghu and some in the period of early Mingzhi. From making extracts and incorporating rhyme categories, it is thought that the rhymes of old style poets in DongYing Poetry Collection were complicated, and that the rhymes of modern style were abided by GuangYun. Comparing ChiZhuanSanJi (敕撰三集) with the rhymes of Chinese poets, it was concluded that Japanese poets when they were creating poems, not only complied with the rules of rhyme books, but also considered the development of Chinese sounds.
