Purpose - This study examines the impact of company ownership nature and of the dual role of CEO and board chair on R & D investment intensity, as well as the moderating effect of this dual role. Most previous research focused on the impact of the dual role of CEO and board chair on firm performance. Design/methodology/approach - This study uses A-share companies listed on the Shenzhen and Shanghai stock exchanges in China from 2008 to 2017. The univariate and the multivariate regression analysis were hired In order to analyze the data. Findings - The results show that there is a significant negative relationship between state-owned companies and R & D investment intensity. In addition, there is a significant positive relationship between the dual role and R & D investment intensity. The effect of state ownership on R & D investment intensity is more negative when CEO-board chair duality exists. This means that in case of state-owned companies, if CEO serves as the board chair, the propensity to invest in R&D is further reduced. Research implications or Originality - This is a pioneering study that considers the joint effect of state-owned companies and dual role on R & D investment intensity in the Chinese economy.

In order to achieve the goal of protecting medical images, some existing watermark techniques for medical image protection mainly focus on improving the invisibility and robustness properties of the method, in order to prevent unnecessary medical disputes. This paper proposes a novel copyright method for medical image protection based on visual secret sharing (VSS) and cellular automata transform (CAT). This method uses the protected medical image feature as well as VSS and a watermark to produce the ownership share image (OSI). The OSI is used for medical image verification and must be registered to a certified authority. In the watermark extraction process, the suspected medical image is used to generate a master share image (MSI). The watermark can be extracted by combining the MSI and the OSI. Different from other traditional methods, the proposed method does not need to modify the medical image in order to protect the copyright of the image. Moreover, the registered OSI used to verify the ownership and its appearance display meaningful information, facilitating image management. Finally, the results of the final experiment can prove the effectiveness of our method.

The rate of conversion to Medical-juridical-persons' ownership of medical institutions has increased rapidly since its start in 1970s in Korea. The most sensitive issue to introduce for-profit medical institutions, ignited particularly by the WTO/DDA negotiations, has sparked considerable debate, stemming largely from conflicting views on the theoretical effects of ownership status on organizational behavior. This study surveyed health-related experts' opinions on allowing for for-profit-firms-owned medical institutions. Some fear that the obligation to maximize the share-holders' return on their investment will cause the medical institutions to eliminate necessary but less lucrative services. They may easily fall under more pressure to generate income, and respond more aggressively than not-for-profit medical institutions to financial pressures. Advocates of for-profit ownership of medical institutions argue that greater responsiveness to the demands of the marketplace will lead to larger investment, higher quality and lower costs to consumers. Referring to both foreign countries' experience and domestic experts' opinions, this study suggests for reform of the current Korean Medical-Juridical-Person(MJP) System. Introduction of so-called “Capital-investment” MJPs is recommended where the properties left in case of their dissolution can be distributed to original investors according to the procedures stipulated in their statutes. However, their annual profits are not allowed to be allocated to investors, but should be reinvested for their medical institutions, as is the case in current MJPs. Their legal aspects are also reviewed in this study.

This study presents the strategic directions for Korean multi-brand fashion stores by running in-depth industry research and market analysis. Over 20 professionals were selected from Korean multi-brand fashion stores for this study and in-depth interviews were conducted to evaluate related subjects. The results of the study were as follows. First, Korean multi-brand fashion stores could be classified into three criteria: operating ownership, merchandise mix, and store identity. Second, operating ownership criterion was chosen for further investigations of strategies and directions of the multi-brand fashion stores. The operating ownership criterion consists of three types; department store types, specialty store types, and boutique types. Each type deploys different buying practice, organizational strategies, and distribution channels. Lastly, the suggested strategic directions for each type are summarized as follows. The 'department store type' should utilize its strong direct buying capabilities and acquisition of merchandising can be more effectively managed. The store should utilize its strong buying power as a tool to develop new private brands (PBs). For 'specialty store type', two key factors have been derived: market share expansion and positioning themselves to become a new distribution channel. To respond to these factors, the store needs to be perceived as a brand then diversify its business. Strengthening its brand will allow it to expand into a new distribution channel and also enable a strategic partnership with its competitor brands. The factors influencing 'boutique type' is personalization and uniqueness. With an emphasis on the uniqueness of products and merchandising it will be able to implement the role as a personal shopper and stylist to provide a very personalized service to its customers.

BIM은 사업차여자간 협업을 요구하는 동시에 3차원 형상 정보와 더불어 개별 사업정보의 공유를 필요로 한다. 이에 따라 BIM 정보에 대한 소유 및 사용권한에 대한 지식재산권, 즉, 저작권 보호에 대한 체계적인 수립을 요한다. 현재 국내 표준계약서는 BIM 정보에 대한 보호를 담기엔 한계가 있다. 본 연구에서는 미국 및 영국의 주요 BIM 표준계약서를 분석하여 이를 토대로 국내 실정에 맞는 법률적 조항과 운용 방식을 추려내었다. 그 결과 소유권은 저작자; 사용권은 라이선스 서브라이선 방식으로 부여, 취소권한을 주되 사업차질에 최소화하는 선에서 제공, 그리고 데이터오류에 대한 책임 역시 최소화함을 명시할 것을 제안한다. 또한 통합 빔 모델은 연합모델로 구축하고 사업진행중 모델 책임자 및 상세수즌을 사전적으로 합의할 수 있는 책임 메트릭스를 제공할 것을 권유한다.

선진국의 자본시장과 비교해 중국 자본시장의 주요한 문제점으로 주가급락 사태를 꼽을 수 있다. 따라서 주가급락 위험을 줄일 수 있는 요인에 관한 연구는 상당히 중요한 의미가 있다. 본 연구는 최대주주의 보유주식 비율에 초점을 두고, 지분율이 증가함에 따라 기업의 경영자를 감독할 유인이 더 높아지는 지와 이를 통해 경영자의 기회주의적 행동이 감소 되는지 검토해보고자 한다. 이를 위해 2009년부터 2019년까지의 중국 상장기업 자료를 수집하고, 실증분석을 통해 최대주주 지분율과 상장기업의 주가급락 위험 간의 관계를 분석하였다. 연구결과에 따르면 국유기업의 최대주주 지분율이 높을수록 기업의 주가급락 위험이 유의하게 낮아진 것으로 나타났다. 이는 국유기업의 최대주주는 정부 기관으로서 경영자에 대한 정부의 감독이 비국유기업의 최대주주보다 더 엄격하기 때문으로 보인다. 본 연구는 최대주주의 지분율이 높을수록 경영자의 기회주의 행위가 감소하며, 기업과 주주 간의 정보비대칭이 완화될 수 있음을 시사한다.

Purpose - This study conducted empirical research on non-financial corporations listed on the stock exchange from 2001 to 2010, focusing on the effects of corporate governance on real earnings management of corporations. In particular, this study examined primarily the impact of the largest shareholder who could use earnings management to pursue his own self-interest, and foreign investors who played a checking role against the largest shareholders. The study also reviewed the relationship between corporate governance and earnings management while also considering corporate growth. Research design, data, and methodology - As for the measurements of real earnings management, abnormal operating cash flow and abnormal production cost were utilized. As for the independent variables, share ratio of the largest shareholder and affiliate person (M) and share ratio of foreign investors (FT) were leveraged. This study excluded those organizations that had changed their fiscal years, those that had not submitted an audit report, corporations under supervision, delisted corporations, corporations that had changed their business type, and so on, from the non-financial corporations out of the publicly traded corporations whose fiscal year ended in December from 2001 to 2010 in addition, KIS values were utilized for the corporate financial data in the study. To verify whether management structure and growth had an impact on real earnings management of a corporation through empirical analysis, a multiple regression analysis model was applied. Result - First, as a result of the analysis, the share ratio (M) of the largest shareholder and affiliate person was found to have a significant positive correlation with abnormal cash flow from operations(ACF) and abnormal production cost (APD). When controlling the growth, the share ratio (M) of the largest shareholder and affiliate person was found to have an insignificant correlation with abnormal cash flow from operations(ACF) but a significant correlation with abnormal production cost (APD). Second, foreign ownership (FT) was found to have a significant positive correlation with abnormal cash flow from operations(ACF) and abnormal production cost (APD) at the confidence level of 1 percent when not including the growth dummy. When controlling the growth, foreign ownership (FT) was found to have a significant negative correlation with abnormal cash flow from operations (ACF) and with abnormal production cost (APD). Conclusion - The results imply that the largest shareholder is closely related to earnings management through real activities regardless of corporate growth. It is also possible to determine from these results that foreign investors are related to earnings management through real activities when not considering corporate growth, but that they would reduce earnings management in the case of considering the growth. Thus, this study verified along with the existing studies that foreign investors were conducting the control function on controlling shareholders.

Purpose - The purpose of this paper is to investigate the determinants of corporate anti-corruption practice disclosure (ACPD) from the perspective of rent-seeking theory. Research design, data, and methodology - Data are hand-collected from corporate social responsibility reports (CSRR) issued by 724 A-share listed firms in China. This paper provides an empirical analysis of the relationship between ownership structure and corporate ACPD as well as its moderating role in the institutional environment. Results - Our findings indicate that rent-seeking is a key factor in influencing corporate ACPD. State-owned enterprises disclose significantly more anti-corruption information than private ones in order to achieve personal promotion of top executives. Monopoly enterprises reported significantly less anti-corruption information than enterprises in competitive industries due to their rent-seeking behavior. The reduction of government intervention and improvement of legal environment are helpful to curb corporate rent-seeking activities and enhance the level of corporate ACPD. Conclusions - Rent-seeking is an important factor in explaining corporate voluntary disclosure in emerging countries. Institutional environment also plays a moderating role in the relationship between ownership structure and corporate voluntary disclosure. Our results are of interest to policy makers, regulators and market participants that are interested in corporate voluntary disclosure and corruption prevention.

This paper studies a series of capital market promotion policies Korea pursued over a 30-year period during its development era (1960s - 1980s). The purpose of this paper is twofold. The first purpose is to understand the policy approaches Korea took, and the second is to extract lessons that can benefit policymakers in the developing world, where capital market promotion is an important policy goal. There are two key features of Korea's capital market promotion policies. First, the government was actively involved, sometimes indirectly by giving tax incentives to encourage IPOs. However, in other times, it was directly involved by giving IPO orders and threatening those that did not comply. No stock exchange in a developed country has ever experienced such government involvement. Combined with rapid economic growth, this interventionist approached allowed the Korean stock market to experience phenomenal growth over a short period of time. Second, the capital market promotion policies had multiple objectives. One was to mobilize domestic capital for economic development. Another was to lower firms' debt-to-equity ratios. Most interestingly, however, the Korean government wanted to popularize stock ownership, thereby allowing ordinary Koreans to share in the fruits of economic growth.
