Background: Korea set up new diagnosis related group (DRG) as demonstration project in 2009. The new DRG was reformed in 2016. The main purpose of study is to identify the effect of reform on accuracy of payment. Methods: This study collected inpatient data from a hospital which contains medical information and cost from 2015 to 2016. The dependent variables were accuracy of total, bundled, unbundled payment, and payment for procedures. To analyze the effect of reform, this study conducted a multi-variate regression analysis adjusting for confounding variables. Results: The accuracy of payment increased after policy reform. The accuracy of total, bundled, unbundled payment, and payment for procedures significantly increased 3.90%, 2.92%, 9.03%, and 14.57% after policy reform, respectively. The accuracy of unbundled payment showed the largest increase among dependent variables. Conclusion: The results of study imply that policy reform enhanced the accuracy of payment. The government needs to monitor side effects such as increase of non-covered services. Also, leads to a considerable improvement in the value of cost unit accounting as a strategic play a role in development of DRG.

The study aims to investigate factors that determine dividend payout policy using 336 non-financial firm year observations covering the period 2005 to 2016 in Malaysia. We found a significant positive relationship between corporate board size, board members average age, board tenure and dividend payout policy. We also found a strong negative effect and statistically insignificant relationship of board diversity, board independence, CEO duality and dividend payout policy. Additional, financial leverage has a negative effect on dividend payout policy. It is also noticed that firms with diverse boards are more likely to pay dividends and tend to pay larger dividends than those with non-diverse boards. Our results suggest that board diversity has a significant impact on dividend payout policy. Impact of board diversity on dividend payout policy is particularly conspicuous for firms with potentially greater agency problems. Our findings are consistent with the argument that corporate board traits enhancement positively affect the dividend payout policy which is beneficial for shareholders. This study offers useful insights into the current global debate on board traits and its implications for firms. The dividend payout policy signals good news to investors. Corporate board traits and firm's financial decision are the factors that disrupt the dividend decision.

This study explores the process in which employees adopt the information security policy. The results of this study, which surveyed 234 employees in three call centers and four hospitals, show that the employees adapt the information security policy through the social structuring process suggested by the AST model. In particular, this study identifies roles of two appropriation activities (FOA : Faithfulness of Appropriation & COA : Consensus on Appropriation) observed in the social structuring process. Regarding to the interactions between the two appropriation activities, FOA, which indicates a better understanding of the information security policy, is examined as a more critical factor than COA, which indicates the degree of agreement among employees about how to use it. FOA not only has a direct effect on compliance intention toward the information security policy, but also indirectly through COA, whereas COA has only a indirect effect through FOA. This result shows that, in order for a company to successfully implement a new information security policy, it is important for employees to understand its purpose and intention. The adaption of information security policy through two appropriation activities is observed in both hospitals and call centers, but due to the different working environments, there were differences in the preceding variables affecting the appropriation activities. The results of this study are expected to provide guidelines for companies who want to successfully adopt information security policy.

The relationship between corporate board attributes and dividend payout is already established yet mediating role of leverage in not been examined in Malaysian market. Therefore, this study aims to examine the mediating effect of financial leverage on the relationship between corporate board attributes and the dividend pay-out policy. A sample of 203 non-financial firms listed on the BURSA Malaysia between 2005 and 2018 were analysed using SmartPLS 3.0. The findings show that there is a partial mediating effect of financial leverage on the relationship between board members age, board diversity and dividend pay-out policy. Financial leverage also mediates the relationship between number of women on board, CEO-duality and dividend pay-out policy. However, financial leverage doesn't mediate the relationship between board size and dividend pay-out policy. This study offers insights to policy-makers to develop a better corporate governance as well as a guidance to firms in the construction and implementation of their corporate governance policies in relation to financial leverage. This study also shed light on the influence of efficient corporate board attributes on dividend pay-out policy and financial leverage for firm growth. This study concludes that corporate board attributes impact capital structure and thus, firms may change its payout policy.

The 52-hour workweek policy in Korea is a system that limits the maximum working hours per week to 52 hours including holiday work, which has been treated separately from overtime work during a week. Although this policy is designed to improve the quality of life and create jobs, it may also reduce the income of some workers. In general, it can be assumed that reduced working hours increase consumption at home. This study analyzed the effect of the 52-hour work policy on meat consumption patterns with the ordered logit model. Major factors considered in this study include working hours, income, and consumption frequency. It distinguished domestic and workplace consumption. The results show that the policy has had an impact on meat consumption patterns both at home and at work. If there is no change in income and only the working hours decrease, meat consumption in households increases. On the other hand, if both income and working hours decrease, household meat consumption decreases. Moreover, reduced working hours decrease the frequency of office happy hour and meat consumption in the workplace. However, the 52-hour workweek policy applies only to workers working more than 52 hours per week; thus, it is difficult to determine the overall effect of the policy on national meat consumption patterns.

This paper considers a preventive maintenance policy following the expiration of renewing warranty, Most preventive maintenance models assume that each PM costs a fixed predetermined amount regardless of the effectiveness of each PM. However, it seems more reasonable to assume that the PM cost depends on the degree of effectiveness of the PM activity. In this paper we consider a periodic preventive maintenance policy following the expiration of renewing warranty when the PM cost is an increasing function of the PM effect. The optimal number and period for the periodic PM policy with effect dependent cost that minimize the expected cost rate per unit time over an infinite time span are obtained.

Background: In 2018, the government increased the fee for the magnetic resonance imaging (MRI) image deciphering services of the external hospital to discourage the redundant MRI scan and to induce appropriate use of the MRI services. It is important to evaluate the effect of the policy to provide the basis for establishing other MRI-related policies. Methods: The healthcare data of the patients who had brain MRI scans were organized by episode and analyzed using the panel study in order to find out the effect of the MRI-related policy on the substitution effect and the medical expenses. Results: As a result of the increase in the fee of deciphering the MRI image, there has been an uplift in deciphering the MRI scan of the external hospital. It implies that more hospitals chose to use the MRI scan taken by other clinics or hospitals, rather than the MRI scan taken at their own facilities. Conclusion: The research results imply that a policy that facilitates the exchange of the medical image data between the hospitals is needed in order to establish an efficient management system of the healthcare resources. Such improvement is expected to reduce the social cost and contribute to the stability in the finance of national health insurance.

Purpose - The policy implications of free trade agreements have traditionally been a matter of debate among economists. The official signing of the Korea-China Free Trade Agreement provides economists with a quasi-natural experiment to analyze the FTA's policy effects. This article aims to more accurately understand the impact of Korea's FTA accession on the macro economy. Design/methodology - This study adopts the counterfactual method based on panel data to find common factors in the generation process of macro data to fit the counterfactual path, to accurately evaluate the effect of the macro policy. Findings - Our research results show that the signing of the Korea-China FTA has a relatively significant short-term positive effect on Korea's economic growth. On average, Korea's real GDP growth rate has increased by 2.1%. This study finds evidence in support of FTA signing not having a significant impact on Korea's GDP growth in the long run. Additionally, we evaluated the impact of the FTA on Korea's imports and exports and found that it had a significant positive impact in the short term, but the trade effect of the FTA is significantly affected by the external macro-environment. Originality/value - First, this study uses macro panel data at the national level to examine the impact of the Korea-China FTA on Korea, and more accurately describes the policy effect of the FTA. Second, our empirical results show that the Korea-China FTA policy impact is subject to occasional changes in the external environment, such as the geopolitical conflict (crisis) between Korea and China, and the US-China trade war. Finally, the analysis shows that the short-term effect of FTA is significant but the long-term is uncertain, which provides empirical evidence for the debate on whether joining FTA can promote national economic growth.

일본은 21세기에 들어와서 경기침체와 디플레이션을 극복하기 위하여 확산적 화폐금융정책을 실시하였으며, 최근 아베정부는 무제한적으로 화폐공급을 증가시키고 있다. 그러나 이와 같은 정책의 효과는 아직 뚜렷이 나타나지 않고 있다. 본 연구의 목적은 2001년 이후 일본금융정책의 효과를 검증하는데 있다. 이를 위하여, 일본에서는 1990년 이후 버블형성과 붕괴이후 민간경제주체의 기대형성 과정이 변하고 있다는 사실에 기인하여, 기대가설을 내포하고 있는 거시모형을 설정하였다. 본 연구에서 사용된 거시모형은 통화량이 환율에 미치는 영향을 포함하였으며, 이를 IVM와 VAR를 이용하여 통계적으로 분석하였다. 통계분석 결과는 다음과 같다. 화폐금융정책의 효과는 2001.01-2015.03 기간에서 1985.01-1994.04.기간보다 낮아졌으며 효과가 미치는 기간도 짧아지고 있다. 이는 버블형성과 붕괴를 경험한 일본 민간경제주체가 더 이상 화폐금융정책의 효과를 믿지 않고 있기 때문인 것으로 판단된다. 통화량의 증가에도 불구하고 총수요는 영향을 받지 않고 있으며, 기대하지 못한 환율의 변화는 순수출을 증가시키고 있지만 통화 증가가 환율의 기대오차에 영향을 주지 못하고 있는 것으로 판단된다. 본 연구의 결과가 금융정책에서 의미하는 바는 중요하다고 할 수 있다. 일본의 버블형성과 붕괴, 그 후의 금융정책의 실패 등은 민간경제주체의 정책에 대한 신뢰를 변화시켰고, 화폐금융정책의 효과는 점차 낮아지고 있으며 불확실성은 커지고 있다. 확산적 화폐금융정책은 효과가 미흡할 경우 그 정책에 내재해 있는 위험성은 높아지므로 정책실시에 보다 신중한 결정이 요구된다. 또한 정부부채를 이용하는 재정정책을 배합하는 방향도 고려할 필요가 있다. 문제는 일본 정부부채 비율이 250%에 달한 것인데, 그렇다고 해서 재정정책을 사용하지 못한다는 근거는 없으므로, 이에 대한 또 다른 연구가 요구되는 시점이다.
