The purpose of this empirical study is to investigate whether costs are 'sticky' -that is, whether costs increase more when revenues rises than they decrease when revenues falls by an equivalent amount by using the financial data fromf korean general hospital Financial data used in this study were obtained from the Database of Korean Health Industry Development Institute and analyzed using multiple regression model in dummy variables. The main results of this study are as follows: First, we found, for 69 Korean general hospitals for 3 years(2000~2002), that total hospital costs, hospital labor costs, hospital administrative costs were sticky, these costs provided strong support for the sticky costs hypothesis 1, but hospital material costs were shown to be proportional to sales revenues. Second, this results provided strong support for the hypotheses that the' degree of stickiness was lower in sales revenues declining that were preceded by revenue-declining periods (hypothesis 2-1), and that stickiness was less pronounced in a second successive year of revenue decline(hypothesis 2-2). Third, this results provided strong support for the hypothesis(hypothesis 3) that stickiness was greater hospitals that employ relatively more people to support their sales revenues(hypothesis 4) that stickiness was greater for hospital that used relatively more assets to support their sales revenues. After all, a managerial implication of this study was that sticky cost, for the general hospital, could be recognized and controlled.

In the field of information security management systems, one of the representative certifications in Korea is ISMS-P certification, and internationally, ISO/IEC 27001 certification is recognized. When companies acquire both ISMS-P (or ISMS) and ISO/IEC 27001 certifications, budget and manpower are duplicated in similar areas. Therefore, it is necessary for the company to choose and invest in a certification that is suitable for its conditions. This paper proposes a strategy for obtaining information security management system certification that is suitable for the characteristics of the company, allowing for effective information security management based on the company's conditions. To achieve this, data were collected from the Ministry of Science and ICT's Information Security Disclosure System (ISDS), the Korea Internet & Security Agency (KISA), and the Financial Supervisory Service's Data Analysis, Retrieval and Transfer System (DART), and Probit regression analysis was conducted. During the Probit regression analysis, the relationships between seven independent variables and five cases of ISMS-P (or ISMS) acquisition, ISMS-P acquisition, ISMS acquisition, ISO/IEC 27001 acquisition, and both ISMS-P (or ISMS) and ISO/IEC 27001 acquisition were analyzed. The analysis results revealed the relationship between company characteristics, including industry, and certification acquisition in the ISMS field. Through this, strategies for certification acquisition based on company types could be suggested.

With the full implementation of open banking in which both banks and fintech companies participate, changes in the whole society such as new types of products, services, and businesses are taking place. Whenever new systems and environments change, research on technology acceptance by system users has been continued, and this study also verified how the characteristics of open banking affect the perceived ease of use and usefulness of the Technology Acceptance Model, and the intention to use open banking. As a result of the study, it was found that both information provision, service interactivity, and system stability had a significant effect on perceived ease of use, usefulness, and intention to use open banking. In the future, open banking may bring significant benefits to data sharing, financial access, banking infrastructure, product innovation and pricing, but it is also expected to bring unexpected damage. Therefore, domestic financial institutions should actively cope with the situation where the business environment is greatly changing due to the digital environment change, and at the same time actively foster fintech companies and promote innovation in the financial industry.

Due to the convergence of broadcasting and telecommunication and the evolution into the media industry, viewers are adapting to the reception of content through various platforms and personal media. Accordingly, public broadcasting is seeking to change into public media that redefines public responsibility and establishes a role for a sustainable society. In particular, proving its value in the form of differentiated public services in an environment where public content is also provided by commercial services is necessary for members of society to prove the legitimacy of financial resources and services. In this paper, as the digital broadcasting era in the 2010s and the media industry was reorganized in 2020, changes in public services corresponding to the public responsibilities required of public broadcasters were analyzed through global public broadcasting cases. In particular, since the technical preparation of broadcasters and viewers is essential in the media environment, the technical direction of public services was mainly analyzed. The derived direction is a common direction applicable to all public broadcasters, including Korea. It is expected that the public responsibility and direction of technological development suggested in this paper will clarify the role of public media and help become differentiated services that contribute to life.

Because of this, domestic small size enterprises is an urgent need of restructuring. Based on the small business data registered in the Credit Guarantee Fund, we estimated the survival probability in the context of the survival analysis. We also analyzed the survival time which are distinguished depending on the types of business in the small business. Financial variables were also conducted using COX regression analysis of small businesses by types of business. In terms of types of business wholesale and retail trade industry and services were relatively high in the survival probability than light, heavy, and the construction industries. Especially the construction industry showed the lowest survival probability. In addition, we found that construction industry, the bigger BIS (bank of international settlements capital ratio) and current ratio are, the smaller default-rate is. But the bigger borrowing bond is, the bigger default-rate is. In the light industry, the bigger BIS and ROA (return on assets) are, the smaller a default-rate is. In the wholesale and retail trade industry, the bigger bis and current ratio are, the smaller a default-rate is. In the heavy industry, the bigger BIS, ROA, current ratio are, the smaller default-rate is. Finally, in the services industry, the bigger current ratio is, the smaller a default-rate is.
