Recently, the Supreme Court of Korea delivered a milestone judgment about air related multimodal transport. At there, the mattered cargo, some expensive jewellery, was transported from Qingdao, China to downtown office of consignee at Seoul via Incheon airport in Korea. As an air waybill was issued in this case, there was an air transport agreement between consignor and air courier operator. After arriving at Incheon airport, the shipment was transport by land arranged by the air courier operator, who was a defendant in this case. Upon arriving at the final destination, it was found that the jewellery was lost partly and based on circumstantial evidence, the damage presumed to be occurred during the land transport. As a subrogee, the insurance company who paid for consignee filed an action against the air courier operator for damage compensation. Defendant contended that Montreal convention should be applicable in this case mainly for limited liability. The lower court of this case confirmed that applying the limited liability clause under Montreal Convention is improper under the reason that the damage in this case was or presumed to be occurred during surface transport. It was focused on the Montreal Convention article 18 which says that the period of the carriage by air does not extend to any carriage by land, by sea or by inland waterway performed outside an airport. However, the Supreme Court overturned the lower court's decision. The delivered opinion is that the terms of condition on the air waybill including limited liability clause should be prevailed in this case. It seems that the final judgment was considered the fact that the only contract made in this case was about air transport. This article is for analysis the above decisions from the perspective that it is distinguishable between a pure multimodal transport and an expanded air transport. The main idea of this article is that under the expanded air transport, any carriage by land, sea or inland waterway only for the performance of a contract for carriage by air, for the purpose of loading, delivery or transhipment is still within the scop of air transport.

This study analyses the difference of contents and tones of arguments among three Korean major newspapers, the Kyunghyang Shinmoon, the HanKyoreh, and the Dong-A Ilbo. It is commonly accepted that newspapers in Korea explicitly deliver their own tone of arguments when they talk about some sensitive issues and topics. It could be controversial if readers of newspapers read the news without being aware of the type of tones of arguments because the contents and the tones of arguments can affect readers easily. Thus it is very desirable to have a new tool that can inform the readers of what tone of argument a newspaper has. This study presents the results of clustering and classification techniques as part of text mining analysis. We focus on six main subjects such as Culture, Politics, International, Editorial-opinion, Eco-business and National issues in newspapers, and attempt to identify differences and similarities among the newspapers. The basic unit of text mining analysis is a paragraph of news articles. This study uses a keyword-network analysis tool and visualizes relationships among keywords to make it easier to see the differences. Newspaper articles were gathered from KINDS, the Korean integrated news database system. KINDS preserves news articles of the Kyunghyang Shinmun, the HanKyoreh and the Dong-A Ilbo and these are open to the public. This study used these three Korean major newspapers from KINDS. About 3,030 articles from 2008 to 2012 were used. International, national issues and politics sections were gathered with some specific issues. The International section was collected with the keyword of 'Nuclear weapon of North Korea.' The National issues section was collected with the keyword of '4-major-river.' The Politics section was collected with the keyword of 'Tonghap-Jinbo Dang.' All of the articles from April 2012 to May 2012 of Eco-business, Culture and Editorial-opinion sections were also collected. All of the collected data were handled and edited into paragraphs. We got rid of stop-words using the Lucene Korean Module. We calculated keyword co-occurrence counts from the paired co-occurrence list of keywords in a paragraph. We made a co-occurrence matrix from the list. Once the co-occurrence matrix was built, we used the Cosine coefficient matrix as input for PFNet(Pathfinder Network). In order to analyze these three newspapers and find out the significant keywords in each paper, we analyzed the list of 10 highest frequency keywords and keyword-networks of 20 highest ranking frequency keywords to closely examine the relationships and show the detailed network map among keywords. We used NodeXL software to visualize the PFNet. After drawing all the networks, we compared the results with the classification results. Classification was firstly handled to identify how the tone of argument of a newspaper is different from others. Then, to analyze tones of arguments, all the paragraphs were divided into two types of tones, Positive tone and Negative tone. To identify and classify all of the tones of paragraphs and articles we had collected, supervised learning technique was used. The Na$\ddot{i}$ve Bayesian classifier algorithm provided in the MALLET package was used to classify all the paragraphs in articles. After classification, Precision, Recall and F-value were used to evaluate the results of classification. Based on the results of this study, three subjects such as Culture, Eco-business and Politics showed some differences in contents and tones of arguments among these three newspapers. In addition, for the National issues, tones of arguments on 4-major-rivers project were different from each other. It seems three newspapers have their own specific tone of argument in those sections. And keyword-networks showed different shapes with each other in the same period in the same section. It means that frequently appeared keywords in articles are different and their contents are comprised with different keywords. And the Positive-Negative classification showed the possibility of classifying newspapers' tones of arguments compared to others. These results indicate that the approach in this study is promising to be extended as a new tool to identify the different tones of arguments of newspapers.
