In case of C-410/11, Pedro Espada $S\acute{a}nchez$ and Others v Iberia $L\acute{i}neas$ $A\acute{e}reas$ de $Espa\tilde{n}a$ SA., ECLI:EU:C:2012:747, the passengers of a flight between Barcelona and Paris, whose baggage had been lost, lodged a claim before a Spanish court, asking for compensation. More specifically, the claimants were a family of four (two adults and two children), and had stored all their personal items in two suitcases, which had been checked in and tagged but never returned to the passengers in question. The four claimants relied on the Montreal Convention, ratified by the EU, which provides that each passenger can claim up to 1,000 SDRs in compensation (i.e. ${\euro}1,100$) in case his or her baggage is lost; thus, they sought to recover ${\euro}4,400$ (4,000 SDRs, i.e. 1,000 SDRs x4). The preliminary reference issue raised by the Spanish court to the CJEU regarded the $Montr\acute{e}al$ Convention's correct interpretation; in particular, it asked whether compensation should be available only to passengers whose lost baggage had been checked in "in their own name" or whether it is also available to passengers whose personal items had been stored in the (lost) baggage of a different passenger. The CJEU held that compensation had to be granted to all passengers whose items had been lost, regardless of whether these had been stored in baggage checked in "in their own name." In fact, it maintained that the real aim of the $Montr\acute{e}al$ convention is to provide passenger-consumers with protection for the loss of their personal belongings, so the circumstance of where these were being carried is not relevant. Nevertheless, the CJEU clarified that it is for national courts to assess the evidence regarding the actual loss of an item stored in another passenger's baggage, and maintained that the fact that a group of people were travelling together as a family is a factor that may be taken into account.

철도 신호제어장치들은 각자 고유의 기능을 수행하면서 각 장치간 통신링크를 통하여 하나의 신호제어시스템을 구성하고 있다. 특히 철도청에서 통합 CTC 시스템을 구축하면서 신호제어시스템 이외의 SCADA나 여객정보안내 시스템 등 외부설비들과의 인터페이스를 통해 기존의 열차제어 기능만을 수행하는 것에서 타 시스템과의 디지털 통신을 통한 종합적인 정보시스템으로 발전하고 있다. 이러한 CTC장치와 외부설비들간의 인터페이스는 철도정보시스템의 발달에 따라 매우 중요한 부분이 되고 있다. 또한 철도청의 주요 노선들이 전철화되어감에 따라 SCADA 장치의 중요성이 증가하고 있으며, 전차선의 가압상태를 CTC에서 파악하는 것은 열차의 안전은행에 있어서 매우 중요하다. 이에 따라 본 논문에서는 기존의 도시철도, 경부고속철도 등의 프로토콜의 분석을 바탕으로 철도청 통합 CTC와 SCADA 장치간 통신을 위한 프로토콜 구조를 제안한다.

A coastal ferries, which serve as a mode between mainland and offshore islands, are frequently used by islanders and travelers visiting islands. Therefore, it is located in a place with good accessibility to the downtown so that users can use it conveniently. However, research on the built environment and walking environment of coastal ferry terminals has not been conducted to ensure that elderly islanders and general travelers can use comfortably the coastal ferry terminal. In this study, with a focus on the coastal ferry terminal space, the walking section was set as 1)the accessibility of the coastal ferry terminal, 2)the built environment for using the coastal ferry terminal, and 3)walking environment in the ferry boarding and disembarkation at the coastal ferry terminal, and 4, 5)walking environment in the ferry. An evaluation tool was developed to measure the walking environment for each walking section, and the importance and satisfaction of users were analyzed using the IPA for the Yeosu Coastal Ferry Terminal. As a result, in the process of approaching the ferry terminal, 'convenience of using public transportation by foot' and 'convenience of using signposts guiding the location and direction of the ferry terminal' were investigated as concentrated areas. On the other hand, the built environment inside the ferry terminal and the walking environment showed that the satisfaction of the users was high. Regarding the walking environment from the ferry terminal to the ferry, the 'surface walking environment of the walking path', 'convenience of walking with luggage', 'convenience of walking in the slope section', and 'convenience of walking in the ferry ramp section' showed low satisfaction. This study can be used as basic data for improving the facilities and walking environment of Yeosu Coastal Ferry Terminal and is expected to be used as data for comparative research with other coastal ferry terminals.

After the deregulation of the aviation market in the United States in 1978, airlines took advantage of the possibilities of the liberalized market and reorganized their networks. Then, the hub-and-spoke networks became widely used in the aviation market. The framework of hub-and-spoke network made it feasible to amplify flight networks. Thus, a number of airlines were able to fly to more destinations than ever before through the networks. Amplification of networks can be implementing through the transfer of passengers, transshipment of cargo, or both most researches have been concentrated on the passenger aspect at airports worldwide. Air cargo, however, has become one of the most significant areas at hub airports to keep their leading position in terms of the provision of services and handling volumes. This paper investigates the connectivity of airfreight networks as the temporal concentrations in current network at Incheon International Airport. In order to evaluate airline flight schedule effects to stimulate hubbing at an airport, the indirect connectivity can be considered to be the number of direct frequencies, the minimum connecting times and the quality of the connection determine indirect connectivity. Therefore the connectivity of freight transshipment depends on both the quality of the connection at the hub airport and the quality of the indirect flight compared to the direct flight. In addressing these issues, this paper analyzes the connectivity of flight schedules using a temporal wave-system structure and estimates the degree of connectivity and quality of connectivity applying the NETSCAN model.

The air market in Asia has already entered upon the age of limitless competition. It means a very important moment in Asia air market. Each Asian country thus has put a lot of effort into a development plan and support to their hub airport. In order to achieve such a plan, first of all we should build closer cooperation system between the two countries Japan and Korea. The Korea and Japan are very fast growing in the northeast countries within the global air transport market. Air passenger and cargo traffic volumes between Korea and Japan have increased dramatically, since the 1990s. In response to such a trend, both countries have opened new airports and expanded existing facilities in the hopes of laying claims to the main international hub airport in Asia. Apart from the trend, air transportation between Korea and Japan's metropolitan areas is the only transportation in substance, even if they are located very closely in geographical position. The air transportation between the two countries shows that it is necessary to get fast and more convenient because of the economic and cultural interchange and exchange concentrated on the metropolitan areas, and that will promote the economic growth of Korea and Japan. However, within the air transportation industry field, there have no sufficient seats/slots to supply the air demand from the capital cities of each country, as well as no counterplan for some problems regarding capacityand sustain ability of metropolitan airports. Thus, it is necessary for us to consider in all aspects and solve them to improve air transportation between Korea and Japan. This paper is to try to demonstrate this matter and from all angles, that is, in legal and political aspects, facilities and given environmental conditions and cooperation between Korea and Japan. I think that it is indeed a great necessary and convenient for many Korean and Japanese tourists to conclude a new 'Open Sky Agreement' between Japan and Korea in order to the prepare the increase of the shuttle flight between Haneda-Gimpo and opening of air route newly for shuttle flight between Haneda and Cheongju as well as opening of air route for shuttle flight between Haneda-Shanghai Hongqiao International Airport and Beijing International Airport for the 2008 Beijing Olympic Games. Furthermore it is a great desirable thing for us to conclude a new 'Open Sky Agreement' in cooperation reciprocally among the Japan, China and Korea for opening the new air route by the shuttle flight.

The purpose of this study is to investigate the actual conditions of the mobility convenience facilities for pedestrians and their perception of the facilities, and thereby provide fundamental material necessary to establish a strategy of improving mobility convenience facilities. This study tried to analyze the characteristics of the mobility convenience facilities for pedestrians. Based on previous studies and "Report of Mobility Facilities of the Mobility Handicapped", this study first chose the evaluation items related to mobility convenience facilities, and then conducted a questionnaire survey and Importance-Performance Analysis (IPA). According to the study results, first, the item that needs intensive improvement was sidewalks, and the detailed indicators for sidewalks were walking safety, convenient facilities for the disabled, and pavement in order. Secondly, the items that need to be maintained were bus and crossroad. Thirdly, the low-ranking items were under-passageway and pedestrian overpass. And lastly, the items that need to be controlled were facilities for passenger terminals and bus terminals. Based on the comprehensive IPA result, this researcher judged the actual use conditions of the mobility convenience facilities in Buyeo-gun, Chungcheongnamdo. Therefore, it was found that it would be urgent to improve the direct walking environment on sidewalks. In this aspect, for future policy decision and facility maintenance, it is desirable to put the item in priority in terms of investment and come up with an improvement strategy.
