본 연구는 전염병이 관광산업의 경영성과에 미치는 영향을 분석하기 위해 메르스 발생 전후 호텔업, 여행업, 항공업의 경영성과에 차이가 있는가를 분석하였다. 분석결과 호텔업의 경우 수익성 지표인 매출액세전 순이익률과 매출액영업이익률이 메르스 발생 전후 통계적으로 유의적인 차이가 있는 것으로 나타났는데 두 변수 모두 메르스 발생 이후 낮아진 것으로 나타났다. 여행업의 경우 안정성지표인 부채비율과 차입금의존도가 메르스 발생 전후 통계적으로 유의적인 차이가 있는 것으로 나타났으며 두 변수 모두 메르스 발생이후 높아진 것으로 나타났다. 또한 활동성지표 중 재고자산회전율이 메르스 발생이후 낮아진 것으로 나타났다. 항공업의 경우 수익성지표 중 매출액영업이익률이 메르스 발생 이후 약간 높아졌으며 활동성 지표 중 총자산회전율이 메르스 발생이후 낮아진 것으로 나타나 통계적으로 유의적인 차이가 있었다. 따라서 관광산업의 경영자는 업종의 특성에 맞게 전염병에 대한 부정적 인식을 완화할 수 있는 마케팅 전략의 수립 등 적극적인 대처 방안을 모색해야 한다.

This study purported to acquire information necessary to improve the management of general hospitals. It tried to determine major indices which represent managerial performance of general hospitals and to identify the managerial characteristics of general hospitals which affect the major financial indices. Eighty-eight hospitals were chosen from 188 hospitals which were subject to standardization audit by the Korean Hospital Association. The results of a discriminant analysis are summarized as followings. First, when a single index was used to measure managerial performance of the sample hospitals, the ration of net profit to total capital was the best index and its discriminant power was 58.14%. The ratio of the number of boardmen((M. D.) and average daily medical cost were highly related to this index. Second, when two indices were used, income growth rte and the ration of net profit to total capital had the highest discriminant distinction ability. Their discriminant power was 61.9%. In this case, the ratio of the number of boardmen(M. D.) was significantly and highly related to the indices. Third, when all three indices-income growth rate, the ration of net profit to total capital and quick ratio - were used together, a discriminant function was statistically insignificant. Therefore, using all three indices was not useful in measuring managerial performance of the sample hospitals. In conclusion, using two indices-income growth rate and the ration of net profit to total capital-was better in measuring manegerial performance of general hospitals than using a single index. The independent variable which affected these indices was the ration of the number of boardmen. The discriminant function was : $D_{GI}=2.77+4.832\times(the ratio of the number of boardmen)$ *G=growth index(income growth rate) *I=profit index(the ration of net profit to total capital)

This study examines the time causal relationship between the operation profit of the listed fashion companies and the macro variables. Operating profit data of 36 listed fashion companies from 2000 to 2017 has been used. Macro variables include household income, household expenditure, number of Korean overseas travelers, number of foreigner travelers and sentiment index. The study results are as follows. First, the number of outbound travelers from Korea has a negative effect on the operating profit of listed fashion companies; however the number of foreigner visiting Korea has a positive effect at 0 time lag. Second, the consumer sentiment index had a positive effect on the sales and the operating profits of the listed fashion companies with a time difference between the 3rd and the 4th quarter. Third, a disposable income has a positive effect on the operating profit of listed fashion companies. Last, educational expenses have a negative effect on operating profit with a time lag between the first and the second quarter. The findings can be used as useful information to analyze the fashion industry and help fashion companies improve their financial performances.

Presently, there are some means of voyage estimations such as Hire base, Charter base, and Anticpated income and expenditure statement of voyage. The former two are the means of estimation for profit of a ship's voyage per a deadweight tonnage adn a month, and it is well used in the case of chartered ships. But it is somewhat meaningless for the shpowner who runs his ships for himself. The latter means for estimation is mainly used in western shipping, and do not set forth simpler way of comparing profit with another voyage or with another ship's employing in other route. And this paper has yielded an index of ship's voyage profit evaluation by building a model of ship's voyage evaluation formula, and the index may be used in evaluation of the new investigation of shipping as well as setting out a shiop in a voyage. The model has yielded a break even curve which may be used for deciding the amount of demurrage and the period of ship's port time for a specific voyage contraction.

Many previous researchers tried to analysis relationship between financial index of hospitals such as revenue, expenses, and profit and hospital outcome such as number of inpatient and outpatient or, between that financial index and hospital size including number of hospital beds. However, these studies did not find exact relationship between financial index and hospital efficiency and productivity. Therefore, purpose of the study explores exact relationship between hospital financial outcome and hospital efficiency and productivity using adjusted inpatient days concept from American Hospital Association. Through the empirical analysis, the researchers find that hospital profit has the U-shape quadratic function to operation ratio. 66.9% of operation ratio is changing point and hospitals with 55.8% through 75.0% of operation ration have experience deficit situation. Considering the hospital circumstance, Korean hospitals would be to maintain general hospital type with various specialty departments.

This study was conducted to analyze if there is a difference between the head hospital and branch hospital by comparing the profitability and operating expenses to patient revenue of oriental medicine hospitals affiliated with universities in order to find whether opening branch hospitals is an appropriate method to increase profitability. Profit indices used for the comparison of head hospital and branch hospital include ratio of operating profit on medical revenue, net-income on medical revenue, net profit to total assets, and operating profit to total assets; and cost indices included ratio of labor costs, material costs and administrative costs. In comparison of profit indices of head hospitals and branch hospitals, head hospitals displayed negative(-) in all four profit index averages while branch hospitals displayed positive(+), showing that branch hospitals have higher profitability. In particular, in the case of head hospitals, ratio of net profit to total assets was -13.6%, while that of branch hospitals was 12.9%, which was higher than 3.1%, the average of Korean oriental medicine hospitals in 2011. As a result of difference analysis between groups of head hospitals and branch hospitals, profit indices of ratio of operating profit on medical revenue, net-income on medical revenue, and ratio of net profit to total assets were found to vary by hospitals, but there was no statistically significant difference between head hospitals and branch hospitals(p<0.1). Only the ratio of operating profit to total assets of head hospitals and branch hospitals indicated significant difference between the two groups, showing that ratio of operating profit to total assets of branch hospitals is larger than that of head hospitals. Meanwhile, the cost indices of ratio of labor costs, material costs and administrative costs in the difference test results did not show significant difference between the head hospital and branch hospital(p<0.1). Thus, it cannot be said that a certain oriental medicine hospital's profitability is high or low depending on whether it is head hospital or a branch as profitability varies depending on the management environment of the hospital. Therefore, oriental medicine hospitals affiliated with universities would need to make efforts to increase their profitability as an individual hospital rather than focusing on whether they are head hospital or a branch.

The purpose of this study is to analyze the relations between publicness and profitability of national university hospitals in Korea. Finance and management data from 2008 to 2010 were collected from balancing accounts and annual reports in 13 national university hospitals. The dependant variables are used profitability indicators which are operating margin, net profit to gross revenues, normal profit to gross revenues. The independent variables are publicness indicators which are medical social work, ratio of medical aid in inpatients, ratio of medical aid in outpatients, publicness index. The results show that operating margin, net profit to gross revenues in profitability indicators are affected by medical social work in publicness indicators. Normal profit to gross revenues in profitability indicators is strong related to medical social work and hospital province in publicness indicators. Based on these results, this study suggests implications to balance the publicness and the profitability in national university hospitals.
