The author examined the origins, the course and the period of introduction of 94 types of vegetables and fruits mainly used in Korea. Then, based on it, the author looks into the relationship between food culture in Korea and those in the Silk Road. Among the vegetables and fruits, 57 types are not originated from Korea 17 types of stem and leaf vegetables, 9 types of root and fruit vegetables. 7 types of fruits, 6 types of seed, 6 types of pomes, 2 types of berries and grapes, and 1 type of nut. Their origins are spread in Europe, Southwest and South Asia but interestingly, they are located near or along the Silk Road. Therefore, it can be presumed that the vegetables and fruits were introduced into Korea from its neighboring countries by way of the Silk Road even before the Three Koreas Period and they were eaten widely in the Joseon Dynasty. Thus, the Silk Road helped some of the vegetables and fruits used in Korea to be introduced into Korea and eventually, contributed to diversifying Korean food culture. The cultural exchange is not one-way but two-way communication and the cultural exchange through the Silk Road is no exception. It is certain that by way of the Silk Road, foods and recipes were introduced into Korea from other countries but at the same time, Korean foods and recipes were propagated to other countries. In the future, more researches and studies should be conducted to find out how the foods and recipes are exchanged among the countries by the way of the Silk Road.

The purpose of this study is to examine the descriptions of the transmission of plague along the Silk Road in Orhan Pamuk's 2022 novel Nights of Plague. Pamuk won the Nobel Prize in Literature in 2006, the first prize for Turkish literature. Pamuk's vast knowledge of epidemiological history, which has long fascinated him, comes to life in this novel as he describes the characters' battles against the plague in the East and West and how the plague was brought to the islands and spread along the Maritime Silk Road. One of the most important trade routes in human history, the Silk Road was not only a link between East and West trade and cultures but also a route for the transmission of bubonic plague during the medieval period onwards. It was this epidemic that contributed to the decline of the Silk Road. In the novel, a plague originating in China strikes the Ottoman coastal cities of Smyrna and Mingheria on its way to Europe via India. The epidemic is contained in Smyrna but the death toll spirals out of control when the plague reaches the island of Mingheria by sea. The spatial setting of the novel is an island, which means that it communicates with the outside world by sea. The only way the plague could have spread to an isolated island was by ship. Rats from different ports and ships would have traveled to other parts of the world or even countries to spread the plague. In Nights of Plague, the fact that the plague reached Mingheria via the maritime Silk Road is also proven by the route of the ships and various narratives. The novel confirms what many scholars have argued, that the Silk Road brought various goods from the East to the Roman Empire, along with deadly diseases, and that the sea routes were an important way for the plague to travel and spread.

중국의 신(新)실크로드 구상인 일대일로(一帶一路) 전략은 중국 내륙지역을 중심으로 한 육상 실크로드와 연해지역을 중심으로 한 해상 실크로드로 나뉜다. 육상 실크로드는 대외교류 확대를 위해 주변 인접국가와의 인프라 연결 및 무역원활화 추진에 더욱 역점을 두고 있다. 해상 실크로드는 해상 인프라 구축과 해양 협력 강화를 일대일로 전략의 핵심으로 제시하고 있다. 본 연구에서는 일대일로의 오통 중에 경제협력과 가장 관련이 깊은 인프라, 자금, 무역 부문의 일대일로 진행상황에 대해 데이터를 기반으로 평가를 개괄하고, 아시아 국가와 특히 중국의 경제에 의존도가 심화되고 있는 북한의 일대일로 전략의 진행상황을 분석하였다. 중국은 일대일로 전략을 아시아 국가들과 인프라 연결을 위한 협력 체계 및 계획을 수립하고 협력 프로젝트를 추진해왔다. 그러나 아직까지 관련 프로젝트의 실행은 초기 단계에 머물러 있는 것으로 파악된다. 자금융통은 그 수준이 높지 않으며 지역별, 국가별, 항목별 격차가 크고 앞으로도 빠른 발전은 어려워 보인다. 무역창통 수준은 인프라 연결이나 자금융통보다 활발하게 무역교류와 투자협력이 이루어지고 있음을 보여주고 있다. 최근 글로벌 경기 침체에 따라 중국의 전체 무역량은 감소하였지만 일대일로 아시아 국가들과 무역규모는 크게 증가하였으며, 투자협력도 직접투자규모가 크게 증대되고 있음을 파악하였다. 아울러 일대일로 추진에 있어서 중국의 ICT 기업의 활약이 두드러지면서 중국의 디지털 일대일로가 아시아국가로 빠르게 확산되고 있다. 중국의 ICT기업은 일대일로의 인접국가인 동남아를 공략하면서 기술 수출과 콘텐츠 수출 등의 방식을 통해 현지에 서비스와 기술 지원을 제공하고, 문화 융합을 추진하는 등 디지털 트랜스포메이션을 주도하고 있다.

In this study, it was purposed to develop the new method for the prediction of pollutant concentration in road tunnels. The new method was the use of artificial neural network with the back-propagation algorithm which can model the non-linear system of tunnel environment. This network system was separated into two parts as the visibility and the CO concentration. For this study, data was collected from two highway road tunnels on Yeongdong Expressway. The tunnels have two lanes with one-way direction and adopt the longitudinal ventilation system. The actually measured data from the tunnels was used to develop the neural network system for the prediction of pollutant concentration. The output results from the newly developed neural network system were analysed and compared with the calculated values by PIARC method. Results showed that the prediction accuracy by the neural network system was approximately five times better than the one by PIARC method. ill addition, the system predicted much more accurately at the situation where the drivers have to be stayed for a while in tunnels caused by the low velocity of vehicles.
