There is scant of research regarding the efficiency measurement of the ship management business. This paper aims to analyze the relative efficiency within the Korean Major Ship management corporations, to select the relatively low effective companies, and to suggest the improvement strategies for those. As a research methodology, Data Envelopment Analysis (DEA) applied to the top 20 corporations among Korean and Foreign Shipping Liners in Korea. To draw out the efficiency of targeted terminals, the number of ship managed is used as an input variables while, the number of crews and the total sales are utilized as an output variables. As a result. Haeyoung Maritime services is the most efficient corporations in Foreign Shipping Liners. Among Korean Shipping Liners, Panstar Shipping, Korea Lines, STX marine and Woolim Shipping are relatively efficient corporations which are scored BCC 1.

This paper aims to examine the location factors affecting small service business performance, especially hair-style service business sales which are assumed to be dependent on outskirts' residents. In contrast to the prior research, this study measures sales amount as business success factors rather than business man's satisfaction level or customers' royalty. The empirical results show that hair-style service business can be determined by visibility and access level of its shop. In addition, its sales can be influenced by hairstyling chair, but its sales per a designer can impacted by hairstyling chair. This study also presents additional examinations about several independent factors which can have influence on hair-style business performance and several location traits that can have an significant influence on its sales volume.

To bridge the research gap in the area of the Fourth Industrial Revolution, we explore the correlation between the core technologies of the Fourth Industrial Revolution and the economic performance of companies. The results show that the technologies have a statistically significant positive (+) correlation with company sales. The size of the correlation is highest for 3D printing (139%), followed by big data (129%), cloud computing (127%), artificial intelligence (78%), and the internet of things (70%). We also found a statistically significant negative (-) interaction effect between the internet of things and 3D printing, cloud computing and big data, and cloud computing and 3D printing when examining the interaction effect of introducing core technologies of the Fourth Industrial Revolution on company sales. This paper represents an early attempt to examine the correlation between the core technologies of the Fourth Industrial Revolution and the economic performance of companies and may serve as a basis for further empirical research.

This study was conducted to determine the location determinants that influence the sales of the "Storyway" convenience stores built at the country's railway stations. The preceding studies were about the convenience stores located in the residence-business areas or along the roadsides. This study, on the other hand, focused on the characteristics of the stations, based on a theory that is different from the existing theories. The targets of this study were the 301 "Storyway" convenience stores doing business in the 198 railway stations in the country, and the dummy parameter and hedonic-price model function were used for multiple regression analysis. For the study results, it was found that the number of people using the railway and the size of the store have a positive effect on the sales whereas the other brand competitors have a negative effect thereon. Second, the subway stations holding 89% of the total passengers in the country have unexpectedly no positive influence on the sales. Third, depending on the transfer, it was found that no transfer station had smaller sales than the transfer stations. Finally, as for the location of the stores in the station, the stores located on the platforms or passageways have a smaller turnover rate than the stores in the welcoming spaces and squares. This research result shows that when starting a convenience store business, the number of people using the railway, the size of the store, the transfer possibility, and the location of the store inside the station have to be considered under the circumstance of recession on the part of the convenience stores due to excessive competition.

항공운송산업에서 항공화물이 차지하는 비중이 점차적으로 확대되고 있으며 향후 2020년(보잉은 2022년)까지의 성장률도 보잉과 에어버스에서는 여객 수요보다 화물수요가 각 1.3%, 0.8%의 높은 성장을 거둘 것이라는 전망을 하고 있다. 특히 에어버스에서는 아시아 태평양 지역 역내와 중국 발 유럽행의 항공화물이 평균 7.0%의 높은 성장을 할 것으로 전망하고 있다. 이러한 높은 성장 전망 외에도 항공화물이 항공운송산업 혹은 세계경제의 선행지표로도 사용되고 있다. 이렇듯 항공운송산업에서 항공화물 부문의 역할이 점차적으로 증대되고 있어 본 연구에서는 항공화물 사업부문에 많은 활동을 하고 있는 항공사의 효율성이 그렇지 않은 항공사의 효율성을 비교하는 연구를 하였다. 먼저 항공 화물 매출액 기준 상위 10개사(2002년 기준)의 효율성을 자료포락 분석(DEA, Data Envelopment Analysis)을 이용 분석하였다. 그리고 이를 이용하여 항공사 전체 매출액 상위 10개사(화물 매출액 상위 10개사를 제외), 미국의 9개 항공사(상위 50대 항공사 중), 기타 10개사를 선정하여 각각의 효율성 비교를 통하여 항공화물 사업을 활발히 하는 항공사와 그렇지 않은 항공사와의 효율성에 대해 상대적 비교를 하였다. 이를 통해 항공화물 사업 부문이 항공사의 경영 효율성에 미치는 영향에 대해 간접 비교를 시도하였다. 분석 결과 항공운송사업중 항공화물 부문이 상위 10대 항공사 효율성이 다른 그룹의 항공사 보다 높게 제시되었다. 이는 항공사의 운송 사업을 화물 운송과 여객 운송 부문의 공동 네트워크의 활용을 통한 시너지 효과를 통해 항공사 효율성을 높일 수 있음을 의미한다.

While total sales of broadcasting business have been increasing, terrestrial broadcasters' sales are stagnant and comprehensive programming program providers(PPs)' sales are increasing. The purpose of this study is to derive implications by analyzing the relative efficiency and super-efficiency of domestic broadcasters in such an asymmetric situation. In this study, we use input and output data of three central terrestrial broadcasters and four comprehensive programming PPs from 2012 to 2019. For the analysis, Additive DEA model and Additive super-efficiency DEA model are used with the assumption of VRS condition since the broadcasting industry is characterized by economies of scale. As a result, we find out that the input excess of tangible assets is the most decisive cause of inefficiency that reduces the efficiency of central terrestrial broadcasters. On the other hand, for the comprehensive programming PPs, the input excess of tangible assets and the output shortfall of total sales are important factors of inefficiency.
