This research executed research that analyze construction cost and profitability through construction example of direction and subcontracting construction based on common private construction less than 3 billion. The results of this research, is summarized as follows. (1) Analyzed profitability about construction gross and operating profit of direction and subcontracting construction. The construction gross profit rate is 15.2% direction construction, subcontracting construction was analyzed by 1.3% high by 16.5% subcontracting construction, and the operating profit rate is 9.4% direction construction, subcontracting construction was construed by 2.3% high by 11.7% subcontracting construction. (2) Analyzed profitability about operating profit before and after deduction of 4 insurance cost of direction construction. The direction construction operating profit rate is 9.4% before deduction of 4 insurance cost, after deduction was construed that is 7.3% and operating profit rate difference after and before deduction was construed that is 2.1%. Therefore, subcontracting construction (operating profit rate 11.7%) was analyzed that last operating profitability after 4 insurance cost deduction produces more 4.4% about direction construction.

An objective of companies' existence is to make profits and grow steadily. Judging what is reasonable or excessive profit for an industry or a company by a profit figure is practically impossible because it is a matter of value judgement not just fact judgement. But recently construction companies' profit level is under severe argument. The objective of this study is to investigate the level of construction companies' profit level and compare it with other industries in order to identify facts and characteristics in relation to construction companies's profit level.

The aim is to analyze a performance evaluation of local governmental public hospitals. Data were collected from public disclosure system DB of National Tax Service on 15 July 2013. Twenty-two income statements of local governmental public hospitals were analyzed using descriptive statistic analysis. The analyzing factors were medical operating profit, contribution margin, and trend of operating profit. The important result was that the medical operating profit was negative, average medical operating profit was -4,678.9 million won. However, the contribution margin was positive in all local governmental public hospitals, and average contribution margin was 12,572.5 million won. The trend of operating profit was positive in 15 local governmental public hospitals between 2011 and 2012. The average increased operating profit was 1,299.1 million won. Through this result, we suggest that not only individual public health hospital perspective, but also the enterprise wide perspective like nation was significantly considered to make decision of closure or maintain of local governmental public hospitals.

Using the Korea Labor and Income Panel Study(KLIPS), this study analyzes the effects of profit sharing on employer-provided training. The estimation results of the fixed effect model that controls for endogeneity show that the workers of profit-sharing firms have a 6.7%-6.8%p higher probability of receiving employer-provided training than the workers of firms without profit sharing. They also show that the workers of profit-sharing firms have a 3.3%p higher likelihood of having employer-provided OJT than their counterparts. The impacts of profit-sharing on employer-provided training appear consistently regardless of the estimation models and in the subsamples. These findings support the hypothesis that profit-sharing promotes employer-provided training.

The purpose of this article is to show profit margin hedging can be an optimal strategy in crude oil purchasing. This study theoretically analyzes profit margin hedging strategy is optimal in crude oil purchasing using expected target utility function and conducts simulations to show if the profit margin hedging is profitable. In addition, this study tests existence of mean reversion of crude oil futures prices to confirm the theory that profit margin hedging is more profitable than other strategies, such as always hedging or buying at expiration with spot price, if futures prices are mean reverting. The simulation results show that the expected utility of profit margin hedging higher than other strategies. Although we cannot find any evidence that crude oil futures prices follow mean reverting process, we can conclude that profit margin hedging can be optimal strategy in crude oil purchasing based on theoretical proof and simulation results.

With regard to conventional theory, the rate of profit is determined by the interaction between the rate of surplus value and the organic composition of capital. And it declines with the capitalistic development through intensifying the organic composition of capital. According to the empirical test, the rate of profit and the rate of surplus value have been decreased. On the contrary, the organic composition of capital have increased during the period under study. The empirical results of the rate of profit in Korean economy appears to hold the principle of the law of the tendency of the rate of profit to fall. But the trend of the determinants is distinct from the conventional theory. Despite the distinctive empirical results, the law of the tendency of the rate of profit to fall is realized in Korean economy in objective period of time.

This paper empirically analyses the effect of labor union on firm's profit rate in Korea. For this purpose a panel data set has been constructed for the period of 1990-2009 using "TS2000", and the data set has been subdivided into two: one is the 'non-variant group' in which firm's union status has not changed, and the other is 'variant group' in which firm's union status has changed from non-union to union during the sample period. It has been found that for 'non-variant group' there is no significant union effect on profit rate. However, for 'variant group' the presence of union has been found to decrease firm' profit rate in terms of return on equity.

This study develops a demand and supply model and price model for Miryang sesame leaf cultivation and predicts the optimal production level to maximize total profit for Miryang sesame leaf farms. We used time series data from 1996 to 2017, which are related to Miryang sesame leaf cultivation. For the analysis, we estimated the demand function and average cost function, calculated the optimal production level and price, and derived the optimal profit. In addition, we predicted the optimal production level, price, total revenue, total cost, and profit until the year 2030 through scenario analysis. The results show that the optimal production level until the year 2030 is between 10 and 12.5 thousand tons, while the production volume was 7 thousand tons in 2017, and total profit for Miryang sesame leaf farms is estimated at 13.3 to 21.3 billion Korean won in 2030. The producer group needs to maintain the optimal production level to maximize total profit for farmers, as suggested in this study.

Financial ratio indicators of the 73 sample hospitals provided by the Korea Hospital Association in 1998-1999, together with the data by the Korea Health Industry Development Institute in 1007, were analysed to identify the financial structure and managerial performance of the profit/loss-making hospitals under the IMF. The major findings of this study were as belows. 1. Among the general characteristics, there was a statistical significance in the hospital location and the number of operating beds between profit-making hospitals and loss-making hospitals. 2. Financial ratio indicators of the profit-making hospitals were better than those of the loss-making hospitals. 3. Financial ratio indicators, including Liquidity, Performance Indicators and Growth Rate Indicators of profit-making hospitals, were better than those of loss-making hospitals except for Turnover Ratios under the IMF economic impasse.
