Has Container Shipping Industry been Fixing Prices in Collusion?: A Korean Market Case

윤재웅,허윤석 한국무역학회 2023 Journal of Korea trade Vol.27 No.1

Purpose – The purpose of this study is to analyze the market power of the Korea Container Shipping Market (Intra Asia, Korea-Europe, and Korea-U.S.) to verify the existence of collusion empirically, and to answer whether the joint actions of liner market participants in Korea have formed market dominance for each route. Precisely, it will be verified through the Lerner index as to whether the regional market of Asia is a monopoly, oligopoly, or perfect competition. Design/methodology – This study used a Lerner index adjusted with elasticity presented in the New Imperial Organization (NEIO) studies. NEIO refers to a series of empirical studies that estimate parameters to judge market power from industrial data. This study uses B-L empirical models by Bresnahan (1982) and Lau (1982). In addition, NEIO research data statistically contain self-regression and stability problems as price and time series data. A dynamic model following Steen and Salvanes' Error Correction Model was used to solve this problem. Findings – The empirical results are as follows. First, λ, representing market power, is nearly zero in all three markets. Second, the Korean shipping market shows low demand elasticity on average. Nevertheless, the markup is low, a characteristic that is difficult to see in other industries. Third, the Korean shipping market generally remains close to perfect competition from 2014 to 2022, but extreme market power appears in a specific period, such as COVID-19. Fourth, there was no market power in the Intra Asia market from 2008 to 2014. Originality/value – Doubts about perfect competition in the liner market continued, but there were few empirical cases. This paper confirmed that the Korea liner market is a perfect competition market. This paper is the first to implement dynamics using ECM and recursive regression to demonstrate market power in the Korean liner market by dividing the shipping market into Deep Sea and Intra Asia separately. It is also the first to prove the most controversial problems in the current shipping industry numerically and academically.

윤재웅 한국주거학회 1994 한국주거학회 논문집 Vol.5 No.2

This study is to analyze the transfiguration of the plan of the Japanese-Western eclectic houses in the process of the change in the living style and modernization. Twenty four Japanese-Western eclectic houses. which were located in Teagu Province and constructed during the period from the end of 19th century to the year 1945. were surveyed and analized about the original plans and the process of their spatial tranfituration. The results of this study are as follews 1) In the original plans. the bathroom, toilet and entrance hall in the residential space and HUSMA(wooden sliding doors) for separation of the rooms had been installed. 2) After the Liberation. the rooms of the residential space had been transfigured from TADAMI. JASHIKI. kitchen and toilet etc. to ONDOL. ANBANG. kitchen and toilet etc of the Korean traditional style. From 1980's they composed of living room, dining room and entrance hall of the Western-style. 3) From the liberation to 1960's. each room of residential space had been transtigured greatly form the Japanese style into the Korean style. Thus as the entrance hall. bathroom and TADAMI has been disappeared. DNDOL and MARU reappeared. Since 1980's bathroom diningroom and entrance hall ef the Western-style have recomposed in their residential space. But ANBANG is still used as a major living space in the surveyed houses.

서정주의 새 자료 「해동사화초」 연구

윤재웅 국어국문학회 2022 국어국문학 Vol.- No.200

서정주의 유품 가운데 새로운 자료가 발견되었다. 1955년 10월부터 11월 사이에 모 일간지에 연재한 것으로 추정되는 신문 스크랩이다. 이 자료는 동국대학교 중앙도서관 미당문고 내부 창고에 보관되어 있는 「해동사화초(海東史話抄)」이다. 서장 포함 전체 17장, 34회 연재물이고 제3회분이 결락되었다. 「해동사화초」는 서정주가 1960년에 제출한 교수자격인정논문인 「신라연구」의 저본이다. 동일한 텍스트라고 할 수 있다. 「신라연구」는 국립중앙도서관에 보관된 등사판 자료여서 활자 인쇄물이 아니다. 제한적인 사람들만 볼 수 있는 경우인데 진창영이 2007년에 서정주 유족의 동의하에 자신의 저서 속에 이를 부록으로 활자화해서 소개했다. 오래된 등사판 문건을 활자화하는 과정에 판독이 어렵거나 불가한 경우, 자체 오식이 있는 경우가 많아서 보완이 필요한 상태였다. 새로 발견된 「해동사화초」가 이를 해결하는 데 도움을 준다. 이 신문 스크랩은 지면 자체의 오류까지 서정주가 직접 자기 필체로 교정하였기 때문에 서정주 감수본이라고 불러도 무방하다. 인쇄공이 잘못한 것을 필자가 직접 교정한 것이다. 그러나 『삼국사기』나 『삼국유사』 원전을 인용하는 과정에서 원문을 잘못 읽은 경우도 더러 있어서 일일이 대조하여 바로잡는 과정이 필요했다. 본 논문은 그런 점에서 서정주의 「신라연구」의 원본 확정을 위한 토대작업의 성격을 가진다. 이 바탕 위에서 한글판 정본 「신라연구」가 완성될 수 있기를 기대한다.

Recently, many companies improving their management performance by building a powerful brand value which is recognized for trademark rights. However, as growing up the size of online commerce market, the infringement of trademark rights is increasing. According to various studies and reports, cases of foreign and domestic companies infringing on their trademark rights are increased. As the manpower and the cost required for the protection of trademark are enormous, small and medium enterprises(SMEs) could not conduct preliminary investigations to protect their trademark rights. Besides, due to the trademark image search service does not exist, many domestic companies have a problem that investigating huge amounts of trademarks manually when conducting preliminary investigations to protect their rights of trademark. Therefore, we develop an intelligent similar trademark search model to reduce the manpower and cost for preliminary investigation. To measure the performance of the model which is developed in this study, test data selected by intellectual property experts was used, and the performance of ResNet V1 101 was the highest. The significance of this study is as follows. The experimental results empirically demonstrate that the image classification algorithm shows high performance not only object recognition but also image retrieval. Since the model that developed in this study was learned through actual trademark image data, it is expected that it can be applied in the real industrial environment. 전 세계적으로 온라인 상거래 시장 규모가 성장함에 따라 국제 및 국내 기업의 상표권이 침해되는 사례가 빈번하게 발생하고 있다. 다양한 연구 및 보고서에 따르면, 해외 기업 또는 개인이 국내 기업의 상표권을 침해한 사례와, 국내 기업 간 발생하는 상표권 분쟁 사례가 증가하고 있는 것으로 나타나고 있으며, 특허청의 보고서에 따르면 기업의 규모가 작을수록 상표보호를 위한 사전 예방활동을 수행하지 않는다고 응답한 비율이 높은 것으로 나타났다. 이러한 문제는 선등록 상표에 대한 사전조사 또는 자사의 상표보호를위해 소요되는 인력과 비용이 원인인 것으로 판단된다. 한편, 국내에서 선등록상표에 대한 사전조사를 위해 상용되는 서비스를 살펴보면 상표 이미지를 활용한검색 서비스를 제공하고 있지 않은 상황이다. 이로 인해 국내 대다수의 기업은 자사의 상표 보호 및 선등록 상표에 대한 사전조사 수행 시 방대한 양의 선등록된 상표를 수작업으로 조사해야하는 문제가 발생한다. 따라서 본 연구에서는 기업의 상표권 보호 및 선등록 상표에 대한 사전조사 수행 시 투입되는 인력 및비용절감과, 국내외에서 발생하고 있는 상표권 침해 문제를 해결하기 위해 합성곱 신경망 기법을 활용한지능형 유사 상표 검색 모델을 개발하고자 한다. 지적 재산권 전문가가 선정한 테스트 데이터를 활용하여지능형 유사 상표 검색 모델의 정확도를 측정한 결과 ResNet V1 101의 성능이 가장 높게 나타났다. 해당결과를 통해 이미지 분류 알고리즘이 단순한 사물 인식 분야뿐만 아니라 이미지 검색 분야에서도 높은 성능을 나타낸다는 것을 실증적으로 입증했으며, 본 연구는 실제 상표 이미지 데이터를 활용했다는 측면에서실제 산업 환경에서 활용성이 높을 것으로 사료된다.
