대중교통 이용자 만족도의 최대 도달 가능 만족도에 관한 연구

윤재웅 대한교통학회 2018 대한교통학회 학술대회지 Vol.78 No.-

본 연구는 대중교통 이용자 만족도가 물리적으로 도달 가능한 최대 수치에 관한 연구이다. 대부분의 선행연구들에선 이용자 만족도를 리커트 척도로 조사하여, 만점에 해당하는 수치를 최대 만족도로 정의하고 있다. 그러나 실제적으로 대중교통 사업자나 정부가 물리적으로 공급할 수 있는 서비스의 최대 수준과 각 개인이 리커트 척도 만점을 부여하는 서비스수준인 기대수준 간엔 차이가 존재한다. 즉, 물리적으로 가능한 최대 만족도 수치에 도달했음에도, 절대적인 리커트 척도점수가 낮은 경우 정책적으로 과도한 추가 투자가 발생할 가능성이 존재한다. 이러한 문제점에 대해 최대 도달 가능 만족도 (Maximum Satisfaction) 지표를 제안하며, 이용자 만족도를 새로운 관점에서 볼 것을 제안한다. 본 연구에 사용된 자료는 대중교통 환승실태 및 이용자 만족도 조사를 통해 수집된 자료이며, 리커트 척도 자료에 대한 분석 모형인 Ordered Logit과 그 변형 형태인 Hierarchical Ordered Logit을 적용하여 분석을 수행하였다.

This Study is to analize the transfiguration of the domestic architecture in the process of modernization. Thirty two houses which were located in Taegu province and constructed during the period from 1886 to 1945, were surveyed and analized about the characteristic and their transfiguration. The modern domestic architecture of Taegu province had been constructed greatly by the missonaries and Japanes. The history of development of modern houses in Teagu province can be devided into three period in accordance with the economic policy, housing style and the method of construction. The first period (1886-1910) was the beginning of the modern house. Most of the mission houses of that period were made with brick structure of korean-western style or colonial style. In the second period (1911-1926), colonial, Japanese-western, Japanese housing style were co-exited in Teagu province. During the third period (1927-1945) new method of construction using reinforced concrete and mortar was introduced, therefore the houses become row house (a two or three-family house) and much simpler.

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.

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.

The aim of this study is to grasp the kitchen work moving line in kichen of the Korean Houses. The results of study are summarized as follow: 1. The Location of kitchen fined out that separate kitchen was transited gradualluy on the same level of dwelling inside. 2. The Equipment of kitchen fined out that decentralized equipment was transited gradually centralization in dwelling inside. 3. The Work quantity of household affairs in present-day houses has radically diminished compared with the traditional houses, because kitchen work moving line was transited form rising and falling movement to horizontral movement.

The purpose of this study was to investigate type of the modern architecture in Daegu province, based on 91 buildings which were built from 1886 to 1945 in Daegu province. The results of this study could be summarized as follows : The modern buildings were built by the western missionary, Japanese, Chineses and Korean. The catholic, built Korean style cathedral and parsonage early in the missionary period, then changed to build Gothic revival and georgian style masonary buildings. The protestant built eclectic buildings. With masonary structure and Korean roof style. Then from 1930's, they started to build Gothic revival style buildings. Japanese built eclectic buildings which mixed with Western and Japan type during the first period. Then, they also started to build Western eclectic building. Chinese built only two buildings during the whole periods and those were Western eclectic style buildings. Korean started to build commercial and school buildings which were Western style from the middle of the second period by nationalist and local commercialist.
