Noise produced by surface transportation vehicles affects our daily lives, penetrating wherver man lives or works. In this paper, a theoretical model has been studied to describe the sound radiation by the surface vibration of in-service tires and studied about an experiment on sound radiation characteristic due to tire vibration. When a tire is analyzed, it has been modeled as a curved beams with distributed sprongs and dash-pots which represent the radial, tangential stiffnes and damping of tire, respectively. The experimental investigation for the sound radiation of a radial tire has been made. Based on the sound intensity and STSF(Spatial Transformation of Sound Field) techniques. the sound pressure and the sound radiation are measured. The comparison of numerically analyzed results with experimental results was made seperately for the tire in rotation. As a result of this study, a program for the prediction of the tire vibration sound radiation was intended to by developed which enables a designer of a tire to foresee the influence of the various design factors on the tire vibration sound radiation.

타이어와 노면의 상호작용에 의해 발생하는 소음에 대한 이론적인 모델에 대하여 연구하였다. 모델은 레디얼 타이어의 벨트 운동을 얇은 셀 방정식들로 가정하고 Bohm이 유도한 운동방정식을 기초로 하였으며 이들 방정식에 요구되는 구조적인량은 타이어의 재질적인 특성을 기초로 유도하였다. 타이어의 회전형태는 이들 방정식들의 정상상태로 부터 계산되고 진통 응답은 전체 종속적인 셀 방정식에 의해 구하였다. 타이어 노면 접지면에서의 힘은 타이어 트레드의 기하학적인 형상과 접지압의 분포를 기초로 계산하였고 소음방사는 심프슨 적분에 의해 계산된다. 여러가지 설계인자의 변화에 대한 효과를 조사하여 저소음 타이어 설계의 기초자료를 확보하는데 목적이 있다.

This paper traces the trajectory of a variety of complicated economic and political developments between China and India - the world's most ancient civilizations connected by rich history. These recent developments, which are heavily acrimonious and include military clashes involving loss of lives, have greatly damaged bilateral relations. The paper examines the reasons behind the bilateral relations dipping to new lows. Aside from specific bilateral disputes like outstanding border problems, China-India relations have been affected by global and regional developments. The paper identifies rising tensions between the U.S. and China, the evolution of the Belt and Road Initiative, and the growth of the Indo-Pacific construct, as the reasons that have expanded distance and mistrust between the two countries. Both China and India are now part of country coalitions aiming to marginalize each other's strategic influences. The paper argues that such efforts by them are going to impact countries in their neighbourhood - such as in Central Asia - by forcing them to make complex choices in the areas of trade engagement and technological development.

Recent research shows that since the early 2000s, the Chinese Communist Party has increasingly used various cultural heritage sites, including Buddhist sites, as soft power agents. Furthermore, in the context of the Belt and Road Initiative, launched by the People's Republic of China, Buddhist temples, representatives, and practices have been harnessed to play a role in the state's agenda. In this context, White Horse Temple, as a feature of cultural tourism in Henan Province, is facing new opportunities and challenges. The article examines the material particularities of reconstructing the temple in light of this trajectory, building on materials retrieved at the site, and online representations of the temple. The author explores how the temple's unique spatiality and characteristics stress the use of soft power which harnesses online and offline cultural and popular trends for state agenda.

Purpose - This research mainly studied with the promotion of "one belt and one road "initiative's strategy and the construction of China, Japan and South Korea Free Trade Zone, China exports urgently needed industrial products to Japan and South Korea, which will not only help digest excess industrial capacity, optimize China's industrial structure, but also promote the economic development of Japan and South Korea. Research design, data, and Methodology - The study conducted a survey on 2018 year new revision of China-Korea Japan's data. Results -This study shows that In this process, multinational enterprises, as pioneers of economic development, play an irreplaceable role. However, due to the differences between laws of different countries and their own corporate culture concepts, enterprises in different countries will inevitably encounter various conflicts in the process of development. Conclusions -This requires our enterprises to have awareness of legal risk prevention in the process of development, and to study the corporate culture of relevant enterprises to truly achieve win-win cooperation.

The Chinese government portrays the One Belt One Road Initiative (BRI) and South Korea President Park Geun-hae's Eurasia Initiative as a win-win opportunity which will hurt nobody's interests, but some South Korean commentators have interpreted it as much more than just a trade and development deal: they focus on the geopolitical implications and the possibility that the balance of power in Asia will be disturbed. South Korea depends upon its maritime-oriented Sea Lanes of Communication (SLOC) in focusing on its alliance with the US to deter North Korean threats and explore its export-based economic growth and development, and yet cannot afford to be left out of these initiatives which could transform the economic and logistical linkage between South Korea and Europe. Given its negative reception by the some pundits, however, South Korea should be more precautious for expressing only full-fledged supports for the BRI and Eurasia Initiative. Opponents of these two initiatives doubt that its putative benefits can be realized, at least in the short term, arguing that creating the necessary rail interconnections may be too costly.

Purpose: This study aimed to provide basic data for the improvement of the standards related to the performance improvement of the firefighting equipment standards for special ambulances. Methods: Among the domestic firefighting equipment standards, the special ambulance standard was compared with the NFPA 1917 standard for the United States automobile ambulance 2019 and European Union European standard EN 1789 medical vehicle and its equipment, a road ambulance. Results: Anti-skid performance based on indoor noise standards, performance standards for interior lights, seat belt warning device, child car seat fixing device, safety handle, auxiliary footrest, and flooring materials should be supplemented. Conclusion: It is necessary to strengthen the production and performance standards for improvement to a level corresponding to the national standards, such as the United States and European Union.

The case where a drain cannot flow backwards, a sewer institution can be unmanageable in this, and a mad is under water momentarily by local heavy nin by the climate phenomenon in spite of not being a lowlands belt has occurred well more than recently. By the flooded mea since it is in the state which has some human bodies at hand, when a short circuit occurs in street lighting pole which is the electric institution thing of a road, the danger of an electric shock accident becomes higher. In this paper, it was going to show improvement plan for grasping the brittle factor of street lighting pole electricity facilities through the on-site survey of street lighting pole electricity facilities, and improving this.

A series of wind tunnel test were conducted on Korean high speed train model to understand the flow physics around the vehicle related to the aerodynamic drag. For the wind tunnel test on high-speed ground vehicle, a moving ground simulation is necessary to predict the aerodynamic drag accurately. So, the models were tested in three wind tunnels with various ground simulation facility including moving belt ground plane system and tangential blowing system. The test results including measured aerodynamic drag and flow visualization showed that a tangential blowing method can be an alternative ground simulation method in short time using conventional wind tunnel.
