A numerical simulation of passenger evacuation in a subway station was performed by coupling the passenger flow analysis and the fire simulation. The algorithm of the passenger flow analysis was based on a DEM (Discrete Element Method) using the potential map of the direction vector for each passenger. This algorithm was improved in the present study as to use finer grid smaller than a passenger in order to resolve detailed geometry of the station and to resolve the behavior of passengers in the bottleneck at the ticket gate considering the collision of passengers to a wall or with other passengers. In the fire simulation, the CO distribution predicted by using CFD was used to take into account the effect of toxic gases on the passengers' mobility. The methodology proposed in the present study could be used in designing safer subway station in case of fire occurrence.

The purpose of this study is to grasp position of Sachon airport-local airport-especially the characteristics of it's air passengers, the distribution of passengers hinterland on their purposes of the travel and on the day of the week, and the spatial structure of hinterland The results is as follows The distribution of the hinterland on the purposes of a passenger's travel shows the hunterland of friend and acquauntance visit is wider than that of business, And the middle level of its size is sightseeing The hinterland of commuting includes only Chinju, so the range of passengers' social activities is wider than that of passenger' economic activities In the distribution of the hunterland on the day of the week, the distnbution of the weekday is wider than that of the holidays, but the passenger travel to Chinju is concentrated on the holidays. As rnentioned adove, the hinterland centenng around Sachon airport is Chinju sity field. Tongyoung. Sachon and Koje city field, Kwangyang city and Namhae, Sanchong, Kosung, Hadong, Uiryoung county field. It is a little different result from the area of reverse commuting of the elementray, middle and high school Leachers living in Chinju That's because air passenger travel mainly occurs in industrial and sighrseeing cities

This paper reviews the Interpretative Guidelines on EU passenger rights regulations in the context of the developing situation with COVID-19 of EU commission. To enlighten the obscurity and to mitigate the economic impacts of the COVID-19, European Commission has published "Interpretative Guidelines on EU passenger rights regulations in the context of the developing situation with Covid-19" on March 18, 2020. The Guideline essentially aims to create a coherent system of rules to assist the passengers, industry and national authorities overall under the unprecedented circumstances across the European Union. To do so, the Guideline is drafted to cover the rights of passengers travelling by air, rail, ship or bus/coach, maritime and inland waterways, as well as the corresponding obligations for carriers. From an aviation industry focused perspective, by referencing the Regulation (EC) numbered 261/2004, the Guideline specifically applies to cancellation and delay in flights which are seen as the dark spots for the air carriers concerning potential burdens.

The summary of the case is as follows: a Korean passenger booked and purchased a business class ticket from Air France that was scheduled to depart from Paris and arrive in Seoul. When the passenger arrived at the check-in counter, he was told that all business class seats were occupied. It was because the flight was overbooked by Air France. The passenger cancelled the Air France flight and took another air carrier. After arriving in Korea, he brought suit against Air France for damages. The purpose of this article is to discuss the governing law when interpreting the contract of international air carriage in accordance with the Korean Private International Act (2001) and to analyze air carrier's civil liability for the bumped passenger in the overbooking case. If the parties have not chosen the applicable law the contract shall be governed by the law of the habitual residence of the consumer in the following situations: prior to the conclusion of the contract, the opposite party of the consumer conducted solicitation of transactions and other occupational or business activities by an advertisement in that country or conducted solicitation of transactions and other occupational or business activities by an advertisement into that country from the areas outside that country and the consumer took all the steps necessary for the conclusion of the contract in that country or in case the opposite party of the consumer received an order of the consumer in that country [Article 27 (1), (2) of the Private International Act]. Since the contract of international carriage falls into the consumer contract, the Supreme Court viewed that the governing law of the contract in this case would be the law of the habitual residence of the consumer (Supreme Court Decision 2013Da8410 decided on Aug. 28, 2014). This interpretation differs from the article 5 (4) of Rome Convention(80/934/EEC) which declares that the consumer contract article shall not apply to neither a contract of carriage nor a contract for the supply of services where the services are to be supplied to the consumer exclusively in a country other than that in which he has his habitual residence. Even though overbooking can be considered as a common industry practice, an air carrier must burden civil liability in case of breach of contract for the involuntary bumped passenger(Seoul Central District Court Decision 2014Na48391 decided on Jan. 29, 2015). In case of involuntary bumping, an air carrier must offer re-routing to passenger's final destination by an alternative flight. If an air carrier fails to effect performance in accordance with the tenor and purport of the obligation, the involuntary bumped passenger may claim damages(Article 390 of the Civil Code).

The South Korean Ministry of the Environment has revised the laws relating to the management of interior air quality for multiple use facilities, and recommends maintaining carbon dioxide ($CO_2$) concentration in passenger vehicles below 1000 ppm during operation in urban areas of large cities. However, the interior $CO_2$ concentration of passenger vehicles can rapidly increase and exceed 5000 ppm within 30 min, as observed when two passengers are traveling in urban areas of the South Korean city of Jeonju with the air conditioner blower turned off and the actuator mode set to internal circulation mode. With four passengers, $CO_2$ concentration can reach up to 6000 ppm within 10 min. To counter this, when the actuator is set to external mode, $CO_2$ concentration can be maintained below 1000 ppm, even after a long period of running time. As part of the air conditioning system, alkali-treated activated carbon fiber filters are considered to be far superior to the commercial non-woven filters or combination filters currently commonly in use.

This study aims to forecast of Air Passenger Demand between South Korea and North Korea using the system dynamics analysis methodology that is based on the system thinking. System dynamics is not only a tool that makes the systematic thought to a model but also a computer program-based analysis methodology that mathematically models the system varying according to time variation. This study analyzed the causal relationship based on the interrelation among variables and structured them by considering various variables that affect aviation cooperation from the perspective of Air passenger demand forecasting. In addition, based on the causal relationship between variables, this study also completed the causal loop diagram that forms a feedback loop, constructed the stock-flow diagram of Inter-Korean model using Vensim program. In this study, Air passenger demand was using by the simulation variable value into System Dynamics. This study was difficult to reflect the various variables constituting the North Korea environment, and there is a limit to the occurrence of events in North Korea.

The passenger cabin of train is generally insulated from exterior environment to ensure the safety of passengers and to enhance the heating and cooling efficiency. Therefore, the IAQ management of passenger cabin is very important in aspect of amenity and health of passengers. In this study, we measured some IAQ factors influencing on the indoor air quality of passenger cabin. The measurement was carried out to investigate the PM-10, PM-2.5, PM-1.0, temperature, relative humidity, carbon monoxide, carbon dioxide leves of KTX. The results showed that the air quality of the cabin was largely satisfactory, but carbon dioxide level was relatively higher. The control of carbon dioxide levels need the extensive research in the future.
