Purposes: The hospitals needs to generate a minimum profit, in order to perform its own role such as providing high-quality medical services. The demand for hospital management is increasing, as the social demands are diversified and the financial transparency is emphasized. The purpose of this study is to compare hospitals management based on Dupont Identity, by various hospital classification. Methodology: This study is based on '2016 Statistics for Hospital Management' provided by the Korea Health Industry Development Institute. The hospitals were classified according to the scope of care, the type of establishment, the location, and the number of beds. We analyzed the general and financial characteristics of over 337 hospitals using the method of Dupont Identity. Findings: Net profit margin (PM) has the biggest impact on return of equity (ROE). By the number of beds, general hospital with 160-299 beds have the highest return on equity (ROE). By location, hospitals in local municipalities have higher return on equity than hospitals in urban municipalities. According to the type of establishment, public hospitals have lower business performance, and although they invest more than private hospitals. Practical Implications: This study can inspire interest and provide understanding in hospital management and financial structure, by analyzing through an intuitive indicator named Dupont identity. It is possible to provide basic data for hospital management methods for each financial elements, in order to increase the profitability of hospitals.

In this paper, I suggest several techniques to estimate covariance matrix and compare the performance of the global minimum variance portfolio (GMVP) in terms of out of sample mean standard deviation and return. As a result, the return differences among the GMVPs are insignificant. The mean standard deviation of the GMVP using historical covariance is sensitive to the estimation window and the number of assets in the portfolio. Among the model covariance, the GMVP using constant systematic risk ratio model or using short sale restriction shows the best performance. The performance difference between the GMVPs using historical covariance and model covariance becomes insignificant as the historical covariance is estimated with longer estimation window. Lastly, the implied volatilities from ELW prices do not lead to superior performance to the historical variance.

This study was performed to assess the financial performance of medical institutions and examine the affecting factors in Taegu metropolitan and Kyungpook province. The major results are as follows ; The liability to total assets was significantly different according to the ownership type of medical institution. It was the highest in the case of juridical person having a special status. The total assets turnover and value added to total assets were significantly different according to the type of medical institution, period of establishment, and ownership type of medical institution. They were higher in the tertiary medical institution, in private hospital and university hospital, and they were increased with establishment period of medical institution. The growth rate of patient revenues were significantly different according to the type of medical institution, period of establishment, and the growth rate of adjusted inpatient days were significantly different by period of establishment. The return on assets and net profit to gross revenues were the highest in private hospital. Private hospital went into the black, but other hospitals went into the red figures. According to the multiple regression analysis for the net profit to gross revenues, ownership type, period of establishment, and management strategy of medical institution were significant It was higher in private hospital and medical institution with prospector management strategy, and it was increased with establishment period of medical institution. In multiple logistic regression analysis for the status of financial performance in medical institution, period of establishment, management strategy of medical institution were significant It was better in medical institution with prospector management strategy and longer period of establishment.

This study was conducted on financial data of 38 economic groups listed on Vietnam's stock market for the period 2009 - 2019 and it aims to provide an empirical evidence on the impact of working capital management policy on performance in all phases of the economic cycle of Vietnamese economic groups. The study uses FGLS estimation method with 2 dependent variables ROA, GOP, independent variables including INV, AR, AP, CCC, dummy variable representing different phases of the economic cycle, variables Control includes CAT, CR, LEV, SZ, GR. Research shows that the greater the level of investment by companies in liquid assets corresponding to a certain level of activity (shown by average days of inventory (INV), average days of collection. (AR), cash flow cycle (CCC)) the lower the rate of return on assets. The study also provides additional evidence of the negative effects of economic crisis on the performance of economic groups. The study also shows that the number of short-term asset cycles has a positive impact on operational efficiency, and the level of debt use has a negative impact on operational efficiency. This result implies that the managers of economic groups can increase the efficiency of businesses through a reasonable working capital policy.

우리나라의 산림자원은 그 양적인 증대에도 불구하고, 임업의 낮은 채산성으로 인해 아직까지 경제적인 자산으로서의 가치를 충분히 인정받지 못하고 있으며, 임가경제통계나 국부통계 등 국가통계에서도 입목자산과 관련해서는 통계자료가 명확하게 제시되지 못하고 있는 실정이다. 따라서 본 연구는 우리나라 입목자산가치를 올바르게 평가하기 위한 방법 및 국가통계 산출 시스템을 구현하는데 최종적인 목적이 있으며, 이를 위하여 기존의 입목자산 관련 국내외 평가 사례 및 문헌 조사를 통해 다양한 평가방법들의 이론과 적용상의 현실적인 문제점들에 대해서 분석하였으며, 분석된 결과를 토대로 평가 대안들을 도출하고 그 타당성을 검토하였다. 본 연구 결과, 임가경제조사를 통한 우리나라 임가의 입목자산가치 평가를 위해서는 벌기령 미만의 산림은 내부투자수익율법으로, 벌기령 이상의 산림은 시장가역산법을 적용하여 평가하는 방법이 가장 합리적인 대안으로 제시되었다.

This study investigates the effect of capital structure on the financial performance of pharmaceutical enterprises which are listing on Vietnam's stock market. The study builds the regression using ROE as dependent variable and four independent variables, including self-financing, financial leverage, long-term asset and debt to assets ratios. In addition, we use other variables as controlling ones, such as firm size, fixed asset rate and growth. We collect data for the period from 2015 to 2019 of all 30 pharmaceutical enterprises which are currently listing on Vietnam's stock market. The least square regression (OLS) is used to test the effect of capital structure to the firms' financial performance. The analysis results show that the financial leverage ratio (LR), long-term asset ratio (LAR) and debt-to-assets ratio (DR) have positive relationship with firm performance, meanwhile the self-financing (E/C) affects negatively to the return on equity (ROE). Upon the findings we suggest that the Vietnamese government should focus on stabilizing macro environment to create favorable environment for enterprises. And the pharmaceutical enterprises should build more reasonable capital structure with higher debt proportion than equity, diversifying loan mobilization channels such as issuing long-term bonds. Additionally, the firms should expand the scale appropriately to maintain development and ability to pay debts.

The article analyzes the impact of capital structure on the firm value of chemical companies listed on the stock market of Vietnam. Data was collected from the financial statements of 23 chemical firms listed on the Vietnam stock market from 2012 to 2019. Quantitative research method with regression model according to OLS, FEM, REM method is used; FGLS method is used to overcome the model's defects. In this research, firm value (Tobin's Q) is a dependent variable. Capital structure (DA), Return on assets (ROA), Asset turnover (AT), fixed assets (TANG), Solvency (CR), Firm size (SZ), Firm Age (AGE), and revenue growth rate (GR) are independent variables in the study. The analysis results show that the capital structure of firms in the chemical industry listed on the Vietnam stock market has an inverse correlation with firm value. Besides, firms with greater asset turnover, business size, and number of years of operation have lower firm value. This article helps corporate executives improve corporate value by adjusting their capital structure properly. Chemical firms adjusted their capital structure in the direction of gradually decreasing the debt ratio and gradually increasing equity. Firms use high debt, which has the effect of reducing the firm value of firms in the chemical industry.

Financial ratios are key indicators of an organization's financial and business conditions. Among various financial indicators, profitability, financial structure, financial activity and liquidity ratios are frequently used and analyzed. Using the structural equation modeling(SEM) technique, this study examines the structural causal relationships among key financial indicators. Data for this study are taken from complete financial statements from 142 hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1998 to 2001 for the purpose of accrediting teaching hospitals. In order to improve comparability, ratio values are standardized using the Blom's normal distribution. The final model of the SEM has four latent constructs: financial activity(total asset turnover, fixed asset turnover), liquidity(current ratio, quick ratio, collection period), financial structure(total debt to equity, long-term debt to equity, fixed assets to fund balance), and profitability(return on assets, normal profit to total assets, operating margin to gross revenue, normal profit to gross revenue). While examining several model fit indices(Chi-square (df) = 178.661 (40), likelihood ratio=4.467, RMR=.11, GFI=.849, RMSEA=.157), the final SEM we employed shows a relatively good fit. After examining the path coefficient of the constructs, the financial structure of the hospital affects the hospital's profitability in a statistically significant way. A hospital which utilizes its liabilities, more specifically fixed liabilities, and makes a stable investment decision for fixed assets was found to have a higher profitability than other hospitals. Then, the standard path coefficients were examined to directly compare the influence of variables. It was found that there were no statistically significant path coefficients among constructs. When it comes to variables, however, statistically significant relationships were found. between. financial activity and. fixed. asset turnover, and between profitability and normal profit to gross revenue. These results show that the observed variables of fixed asset turnover and normal profit to gross revenue can be used as indicators representing financial activity and profitability.

본 연구는 OECD 평균 수준의 소득대체율 대비 실현 소득대체율이 부족할 위험을 최소화하는 자산배분안을 제안하는 데 그 목적이 있다. 이를 위해 본 연구는 소득대체율 부족 위험을 정의하고 이를 최소화하는 최적 자산배분안을 퇴직연금제도 가입기간, 가입자 소득수준, 추가부담금 수준별로 산출하여 제시하였다. 이를 위해 본 연구는 투자의 대상으로 주식과 예금을 고려하였으며 주식의 경우 GBM 모형에 몬테카를로 시뮬레이션을 수행하여 수익률 분포를 생성하였다. 분석결과, 퇴직연금제도 가입 기간이 30년 이하인 경우, 가입자는 적립금의 최소 70~80%를 위험자산에 투자해야 소득대체율 부족 위험을 최소화할 수 있는 것으로 나타났다. 다만, 가입자가 부담금을 추가 납부할 경우 위험자산의 최적 투자 비중은 큰 폭으로 하락하였으며, 이러한 효과는 저소득자에서 크게 나타났다. 따라서, OECD 평균 수준의 소득대체율을 달성하기 위해 정부는 가입자들이 일정 수준 이상의 적립금을 위험자산에 투자할 수 있도록 유인하는 가운데 저소득층에게는 추가부담금 납입을 유인하기 위한 보조금 정책 등을 검토할 필요가 있다.
