This study was attempted to identify the factors affecting profitability of general hospital in Kyung-In Region. Operating profit to gross revenues and net profit to gross revenues were used as a proxy indicator for profitability of hospitals. The unit of analysis was hospital, and the data were collected 5 years data from 20 hospitals. The major findings are as follows; (1) The average operating profit rate was 1.03% and the net profit rate was -5.00% in twenty hospitals in the Kyung-In Region for the last five years. In terms of maximum surplus, the operating profit rate was 14% and net profit rate was 3.40%. In terms of maximum loss revenue, the operating profit rate was -16.56% and the net profit rate was -22.83%. (2) Since the year 1993, which was the starting year of this study, the operating profits and the net profits consistently decreased. (3) Analyzing the difference in profits among various hospital groups, the tertiary hospital group and the 501-1000 beds group exhibited the highest in operating profit rate. Also, among the higher grade number of beds in hospital group, per 100 beds group, the 41-50 beds group exhibited the highest in operating profit rate. There is a statistically significant difference in those groups(p<0.05, p<0.01). (4) In the health care delivery system, the profit gain in the secondary hospital was 51.5% and in the tertiary hospital was 72.4%. Based on the number of beds in each hospital group, the highest profit gain was 75.0% in the over 1001 beds group, and 71.4% in the 501-1000 beds group. Also, among the higher grade number of beds in hospital group, per 100 beds group, the 41-50 beds group exhibited 88.6% surplus. (5) According to the surplus difference based on the analysis of health care utilization, a group with over 31 patients in bed turnover rate, a group with over 96% in bed occupancy rate and group with over 9% in emergency cases to outpatient visits exhibited the highest profit gains. In addition, a group with over 301 patients in daily outpatient visits per 100 beds and group with 11-12 days average length of stay exhibited the highest profit gains. These results are statistically significant(p<0.05, p<0.01). (6) According to a stepwise regression analysis, the variables measuring the bed turnover rate, number of licensed beds, and number of outpatient visits per specialist explain 34.1% of the variation in operating profits. In terms of net profits, the new outpatient visits, the bed turnover rates and the number of general bed variables explain 30.6%. These results are statistically significant(p<0.01).

전통적 이론에 의하면 이윤율은 일반적으로 자본의 유기적 구성과 잉여가치율 사이의 상호작용에 의해 결정된다. 그리고 이윤율은 자본주의적 발전과 함께 자본의 유기적 구성이 심화됨으로써 저하하는 것이다. 실증분석에 의하면 이윤율과 잉여가치율은 각각 저하한 반면 자본의 유기적 구성도는 상승한 것으로 나타났다. 실증분석의 결과를 볼 때 한국경제에서는 이윤율 저하경향의 법칙이 관철되는 것으로 보인다. 그러나 그 결정요인들의 추세는 전통적 이론에서와는 다른 것으로 나타났다. 이러한 차별적인 추정결과에도 불구하고 분석 대상 기간 동안 한국경제에서 이윤율 저하경향의 법칙이 실현된 것으로 나타났다.

Since depositors are motivated by returns, it is important for Islamic banks management to understand the extent that rates of return on deposits influence their customers' decision to deposit. The main objective of the study is to explore the degree of influence of conventional bank's interest rate on Islamic bank's profitability and vice-versa. It has been seen from 2005 to 2011 that the rate of interest declared on deposit by conventional banks has a negative impact on profitability of both types of banks in Bangladesh. Rate of profit declared on deposit by Islamic banks is positively related with their profit earned but negatively related with profit earned by conventional banks. We see that rate of interest declared on deposit by Conventional Banks is positively related with their deposit volume but negatively related with Islamic Bank's deposit. On the other hand, rate of profit declared on deposit by Islamic Banks is negatively related with deposit levels of both types of banks. The survey result shows that almost 85% of the respondents are choosing Islamic banks only from their religious point of view and more than 60% of the sampled Islamic bank customers are reluctant to leave the bank even if conventional banks offer better interest rates.

직접시공이나 하도급시공은 건설산업기본법에 의해 정한 시행령에 따라 시공하는 것이 원칙이나 직접시공이나 하도급시공시 수익성을 비교하여 이익 창출을 극대화하는 방향으로 의사결정이 된다. 이 연구에서는 민간공사 사례를 바탕으로 직접시공과 하도급시공의 공사원가와 수익성을 비교분석하였다. 자료 수집은 S건설에서 2002년과 2003년에 공사한 근린생활 및 단독주택을 토대로 하였다. 공사건수의 사례는 직접시공과 하도급시공 각각 3건의 공사에 의한 평균비율 값에 의하여 비교분석하였다. 이 연구의 사례를 분석한 결과, 공급가액 대비 매출총이익에 대한 수익률은 하도급시공이 직접시공 보다 1.3% 높은 수익률을 올린 것으로 분석되었다. 영업이익에 대한 수익률은 하도급시공이 직접시공보다 2.3% 높은 수익률을 올린 것으로 분석되었다. 마지막으로 하도급시공(영업이익률 11.7%)이 직접시공 공사에 대해 4대 보험료 차감후의 최종 영업 이익률이 4.4% 더 많이 발생한 것으로 분석되었다. 그러므로 건설회사는 하도급을 주는 것이 수익률이 높다는 것을 알 수 있고, 노무자 관리 또한 용이한 것으로 나타났다.

To figure out the impact of debt financing on the profits of industrial enterprises, it starts with calculating the first differences against the logarithms of the cost profit ratios and the debt asset ratios of Chinese industrial enterprises during 179 months from 2002 to 2016; next, it runs the cointegration test and afterwards the regression test to analyze the obtained first differences, and still next uses the Simulink software to get the regularity of those changes. It finds out that there is not only a long-term stable relationship between the enterprises' profits and debts, but also a steady time series trend within a short term. The profit rate positively correlates to the debt asset ratio, and profit for the current term positively correlates to the profit for the previous term. It indicates that properly raised debts can help increase the profit rate of the industrial enterprises, and a higher previous profit level can help improve the current profit level.

This article concerns a profit model in a repair limit replacement problem with imperfect repair. If a system fails, we should decide whether we repair the failed system (repair option) or replace it by new one (replacement option with a lead time). We assume that repair times are random variables and can be estimated before repair with estimation error. If the estimated repair time is less than the specified limit (repair time limit), the failed unit is repaired but the unit after repair is different from the new one (imperfect repair). Otherwise, we order a new unit to replace the failed unit. The long run average profit (expected profit rate) is used as an optimization criterion and the optimal repair time limit maximizes the expected profit rate. Some special cases are derived.

기업 존재의 목적은 정당한 이윤창출을 통해 지속적으로 성장 발전하는 것이다. 건설기업의 경우도 예외일 수 없다. 그러나 최근 정부의 강력한 부동산 대책이 분양가 상한제와 분양원가 공개로 이어지는 과정에서 건설기업의 '폭리(暴利)'에 대한 시민단체의 주장이 강하게 대두되어 왔다. 한 산업 또는 기업의 적정 이윤 또는 폭리 수준을 계량적인 수치로 정의한다는 것은 사실상 불가능하다. 본 연구의 목적은 국내 건설기업의 이윤 현황을 다양한 이익률 관점에서 조명하고 이를 타(他) 산업분야와 비교 분석하여 국내 건설기업의 이익률 실태와 특징을 도출하는데 있다.

The objective of this study is to analyze a current trend of and relating factors on profitability of the Korean Public Corporation Medical Centers(KPCMCs, hereinafter, hospitals) in Korea. There are 34 hospitals in Korea as of 2004. Among these hospitals some are red ink hospitals, others are black inks in terms of profitability. Data were collected by Korea Health Industry Development Institute(KHIDI) Statistics for Hospital Management 2000-2002 and Ministry of Health and Welfare(MOHW) financial data of public hospitals which was planned to coordinate public health care services roadmap in the long run. The samples are 32 hospitals. Profitability was measured in the aspect of profit rate with normal profit to total assets, and normal profit to gross revenues as dependent variables in respective. Independent variables were classified by general factors, i.e., location, intern/resident training, period of opening, number of beds, and managerial factors(current ratio, fixed ratio, liability to total assets, total assets turnover, personnel costs, materials cost, administrative cost), and finally factors related to patient treatment(average length of stay, bed occupancy rate, admission ratio of outpatients). The methods of analysis are correlation and multiple regression analysis. This study shows firstly, a lot of hospitals are optimal current ratio. Hospitals in upper 100% current ratio are 81.2%. And the personnel cost in total costs are high. Secondly, the trend of normal profit to gross revenues of hospitals are deteriorating gradually. And lastly, as a result of multiple regression analysis, the factors had on significant effect on normal profit to total assets are fixed ratio(+), liability to total assets(-), bed occupancy rate(+), admissions of outpatients(+), etc. And the factors had on significant effect on normal profit to gross revenues are current ration(+), fixed ratio(+), personnel cost(-), administrative expenses(-), admissions of outpatients(+), etc. In conclusion, to improve the profitability of hospitals, the efforts to reduce personnel cost and average length of stay might be needed. And also beds utilization rate need to be increased.

This paper presents inventory models for fresh agriculture products with time-varying deterioration rate. Due to the particularity of fresh agriculture products, the demand rate is a function that depends on sale price and freshness. The deterioration rate increases with time and is assumed to be a time-varying function. In the models, the inventory cycle may be constant or variable. The optimal solutions of models are discussed for different freshness and the deterioration rate. The results of experiments show that the profit depends on the freshness and deterioration rate of products. With the increasing inventory cycle, the sale price and profit increase at first and then start decreasing. Furthermore, when the inventory cycle is variable, the total profit is a binary function of the sale price and inventory cycle. There exist unique sale price and inventory cycle such that the profit is optimal. The results also show that the optimal sale price and inventory cycle depend on the freshness and the deterioration rate of fresh agriculture products.
