The volume of transfer passengers now faces a crisis because the number of Chinese and Japanese passengers, the majority of transfer through Korea, is decreasing. This paper is analyzing the their air travel behaviors as well as characteristics of their transfer behaviors at airport. According to the research, it is suggested that transfer passengers perceive the importance of duty-free stores but their satisfaction of using duty-free stores during their transfer at Icheon airport was proven to be low. Considering the characteristics of transfer service quality at Incheon airport, waiting time of transfer is important but not satisfactory for them. Moreover, information of free transfer tour to city downtown and paid-in transfer tour for medical tourism is not known very well among North East Asian passengers. Thus, it is necessary to do detailed research of North East Asian transfer passengers, who have transferred through Incheon airport more than twice a year, to find out their exact needs of transfer tour in Korea.

인터넷 및 방송서비스의 QoS 보장을 위한 10Gbps급 스트리밍 패킷 스케줄러 구조 및 제어방법

본 논문에서는 초고속 패킷 스위치 네트워크에서 VoD나 HDTV, VoIP같은 고품질 스트리밍 서비스의 QoS를 보장하는 패킷 스케줄러의 구조 및 제어방법을 제시한다. 스트리밍 서비스는 버스트 데이터 응용서비스보다 더욱 엄격한 QoS(jitter, delay, packet loss)보장을 요구한다 또한 스트리밍 서비스는 다른 플로우들의 동작에 상관없이 끊김 없는 서비스를 제공하기 위해 각 플로우별로 최소 대역 보장과 종단간 지연조건을 보장해야 한다. 이들 요구조건들을 만족하기 위해, 패킷 스케줄러는 플로우들이 다른 플로우의 영향을 받지 않도록 분리하고, 각 플로우들에게 종단간 지연 보장을 제공해야 한다. 그리고 각 플로우들에게 요구되는 최소 대역폭을 할당해야한다 지금까지 많은 벤더들이 10Gbps급 트래픽 관리기 칩을 개발하였지만 대부분 칩들은 고품질 스트리밍 서비스를 지원하지 못하는 단점이 있다. 따라서 본 논문에서는 상용 TM칩들의 단점 및 스트리밍서비스의 트래픽 특성을 조사하고, 제안한 패킷 스케줄러의 하드웨어 구조를 제시한다. 그리고 마지막으로 제안한 스케줄러의 시물레이션 결과를 분석하였다. This paper presents architecture and control method of packet scheduler to guarantee QoS of high quality streaming services in high-speed packet-switched networks. Since streaming services need far more stringent QoS requirements than the typical sort of burst data applications, they should be guaranteed minimum bandwidth and end-to-end delay bound to each flow, regardless of the behavior of other flows. To meet these requirements, a packet scheduler isolate a flow from the undesirable effects of other flows and provides end-to-end delay guarantees for individual flow and divides stringently the available link bandwidth among flows sharing the link. Until now, many vendors are developing traffic management chips running at 10Gbps, but most of chips have drawbacks to support high quality streaming services. In this paper, we investigate the drawbacks of commercial TM chips and traffic characteristic of streaming services and present implementation frameworks of the proposed packet scheduler. Finally, we analyze the simulation results of the proposed scheduler.

Korea meteorological administration(KMA) has started to levy air meteorological service charge on both national and foreign carriers since 2005. The charge has grown on 2010 and 2014 twice. However, KMA has still kept asking airlines to agree with another increase in the charge due to the low cost of goods recovery ratio of 7%. The air meteorological charge has changed from 2,210 KRW at the beginning to 11,400 KRW as of June 2018. According to ARIMA intervention time series analysis, it was proven national carriers would make a payment of 831 million KRW 2018 and 1,024 million KRW 2019, showing 186.2% and 123.2% increase compared to last year respectively. The total amount of charge for both national LCC and foreign airlines was aggregated up to 1,952 million KRW 2019, 227% bigger than the charge paid at 2017. Considering the 50% increase of consumer price index last decade, the increased charge would impair the global competitiveness of national carriers. It could be suggested that current air meteorological charge scheme be improved to apply overseas trend and for national carriers to have a competitive advantage in global aviation market.

〈웃찾사〉의 웃음의 형식적 특성

김광옥(Kwang-Ok Kim),서규하(Kyu-Ha Seo) 동서언론학회 2006 동서언론 Vol.10 No.-

본 연구는 SBS TV의 코미디 프로그램 〈웃음을 찾는 사람들〉 중 〈행님아〉의 웃음의 형식에 대해 분석하였다. 코미디프로그램은 사회적 유행어를 만들어 내는 산실이기도 하다. 2005년 방송되어 2006년 5월 종영되기까지 1년 반 동안 큰 인기를 끌었다. 웃음의 형식에 대해 분석해 본다. 서사구조로는 김신영과 그의 형 김태현이 주축이 되고 중간에 노부부가 등장한다. 키가 작고 뚱뚱하고 당당한 동생과 키가 크고 잘 생기고 약하고 비굴한 형은 동생을 골탕 먹이는 구도를 갖는다. 유형은 콩트 퍼포먼스다. 계열체 분석으로는 대립적 측면에서 동생과 형은 이항적 대립구조(binary opposition)의 속성으로 정리된다. 노부부는 다시 이 형제에게 짓궂음으로 참여한다. 유사적(resemblance) 측면에서는 동생이나 형도 모두 고아이고 촌스럽고 사투리를 쓰고 외로운 존재다. 이런 성질에 수용자가 일부 감성적으로 참여하며 즐기고 만족한다. 중반부분에서 캐릭터의 등장 시, 부모를 그리워 할 때, 끝나는 때 정해진 BGM을 통하여 극적 분위기를 살려 긴장을 지속시켜 나간다. 〈행님아〉는 잊어버린 고향과 어려운 시절의 향수를 고아 출신의 대립적 두 형제를 통해 수용자들에게 따뜻하게 다가가는 형식을 통해 인기를 얻을 수 있었다. 사회 풍자 혹은 여운이 남는 메시지가 없는 즐거운 가족에 대한 향수 코미디라 하겠다. Recently TV comedy program keeps its firm footing in each TV broadcasting station, increasing its attractions to the audience. It creates social vogue words. One example is "Oh! Brother" in PSL produced by SBS TV. This program has been on the air for one and half years from 2005 till in May 2006. This paper aims to look into the qualities of laughter in PSL. 1. Narrative Structure: Kim Shin-young and his elder brother, Kim Tae-hyun play the major roles with the aged couple showing up in the middle part. Kim Shin-young is disappointed to see his teacher in trousers instead of her skirt into which he wanted to look through his looking glass. His next door grandma says she will let him look into her own skirt while he feels sad about his mother's death. His elder brother tells a lie to him that he will show the younger brother a picture of his mother at the end(on the air on May 4, 2006). 2. The younger brother is short, rather fat, and is overpowering while the elder brother is tall, handsome, weak and mean. The basic plot here is that the elder brother is giving hard times to the younger brother. 3. The show pattern is format conte performance. 4. The Paradigmatic Analysis: ?Oppositional Perspective: The two brothers are in binary opposition. The aged couple is involved with scolding at them. ?Resemblance: The two brothers, younger and elder, are all orphan. They take a rustic air, speak dialects, and are lonely. On top of that, the audience emotionally participates in the show in amusement and in satisfaction. 5. The middle part of the show introduces characters, describes their longing for parents, and the closing part retains dramatic tension by creating dramatic atmosphere through BGM fixed. "Oh! Brother" was able to gain its attraction through its warm approaches to the audience by means of binary opposition between two orphan brothers who are home-sick and nostalgic for their hard times. This is a social satire or a nostalgic family comedy for amusement with reverberations but without a message.

근대 일본의 豊臣秀吉ㆍ임진왜란에 대한 인식

김광옥(Kim Kwang-Ok) 부산경남사학회 2007 역사와 경계 Vol.64 No.-

It is well known that Toyotomi Hideyoshi had brought great damage to the Korea during the Japanese invasion to Korea in 1592. In Korea, however, it has not been introduced enough about his life story or the meaning of his roll in Japanese history. In the middle of the nineteenth century, the new Meiji government estimated his achievement highly and restored his shrine. Toyotomi Hideyoshi became popular especially through the Sino-Japanese War, because the government accomplished Hideyoshi's failure of invasion to Korea at 300 years ago. Until the surrender of Japan in 1945, he had been the most popular hero. Toyotomi Hideyoshi is important to understand unification process of Japan in the late sixteenth century, what is more, in Edo periods. It can be said that there are many studies about his biography in Edo period. Still, there are few studies of how Toyotomi Hideyoshi has been appreciated since modern period in Japan. Toyotomi Hideyoshi was considered more important in modern periods compared to Edo periods. In this paper, I want to survey Japanese consciousness about Toyotomi Hideyoshi and his invasion of Korea thoroughly. Various media would be examined such as songs, plays, festivals, not to speak of literary works. Since modern period, Japanese consciousness about him has been changed by several times. That is the Sino-Japanese War, the invasion of the continent, and the Pacific War. After the Sino-Japanese War and Three Hundred Yerar's Anniversary of Toyotomi Hideyoshi's Death (豊臣秀吉三百年祭), The image of Toyotomi Hideyoshi has been ‘invented' as a character who is a devoted retainer of the Emperor of Japan, and the best model of humanity and greatness. This image has been engraved on Japanese people through educations, movies, plays, novels, and so on. Moreover, due to the Japanese invasion to the South East Asia and the invasion to the continent after 1930s, his image changed from a pioneer of the invasion of Korea, to that of the continent and the South. It is necessary to understand accurately that the historical remains of Toyotomi Hideyoshi have been restored too exaggeratively.
