This study scrutinizes the necessity and cases of the public and pension cooperation and tries to present the way of construction of information infrastructure for the pension systems suitable for Korea. The developed countries have recently been focusing on strengthening the multi-pillar pension system, while pension education and information services have emerged as an important element of the pension cooperation. The frame of the multi-pillar-pension system in Korea has already been constructed, but it is not substantial. Especially bad information on the pension system has seriously hindered the consolidation of the pension system. In order to solve this problem, we analyzed cases of public-private cooperation systems in Iceland, New Zealand, Netherlands, and Sweden. In order to build a basic infrastructure for construction pension cooperation in Korea, it is necessary to promote information exchange and cooperation among pension organizations and to improve the pension portal of NPS 'My Pension'. In addition, this study suggests establishing an association of private and public pension schemes, which manages the integrated information and education of pension systems.

Augmented reality game has differences with traditional games in the way what it includes physical risks happened in the real world. Although accidents related to Pokemon Go are increasing, academic discussions on the issues are rare. Thus, this study explores risk types caused by the augmented reality game and examined how perception of the risks affect usage intention on the game. This study also provides the research implications through comparative analysis between youth group who generally has the tendency toward game addiction and older group. According to the results, teenagers had less usage intention when perceived financial risk increase. In case of over twenty, time risk had negative relationship with usage intention. Physical risk had no significant effect on usage intention for teenagers, but positive relationship was observed in case over twenty. These results imply the necessity of an appropriate regulation for safe game play.

Nowadays, fintech becomes the key technology of the mobile banking and payments. Financial market is moved to fintech-based non-face-to-face trade/payment from traditional face-to-face process in Korea. Core of this transition is the smartphones, which have several sensitive sensors for personal identifications such as fingerprint and iris recognition sensors. But it has some originated security risks by data path attacks, for instance, hacking and pharming. Multi-level certification and security systems are applied to avoid these threats effectively, while these protections can be cause of some inconvenience for non-face-to-face certifications and financing processes. In this paper, I confirmed that it have sensible differences correspond with the data connection paths such as WiFi networks and mobile communication networks of the smartphones, and I propose a gradual certification method which alleviates the inconvenience by risk-level definitions of the data-paths.

Purpose - Vietnam has the fastest growing digital economy in Southeast Asia and is emerging as a critical overseas market for Korean banks in the post-COVID-19 era. Accordingly, many Korean banks entered the Vietnamese market to overcome the limitations of the saturated domestic financial market and create new revenue sources. This study examined the current status of digital finance in Vietnam and the cases of Korean banks that have succeeded in the Vietnamese market. Then, importance-performance analysis (IPA) was conducted on local customers, managers and staff members of Korean banks in Vietnam. Design/methodology - In this study, we analyzed the importance and satisfaction factors of mobile banking app usage in Vietnam through IPA. In particular, we identified the differences between the two groups by considering the viewpoint of customers who use mobile banking apps and that of managers and staff members who provide mobile banking services. Findings - The IPA results from the customer group and managers and staff members group were generally similar, but differences were observed in Ease of Use (Technology), Innovativeness (Organization), and Increase in Revenue (Economic). In the case of the customer group, Ease of Use (Technology) is located in the second quadrant, which shows low satisfaction compared to high importance. However, in the managers and staff members group, Ease of Use (Technology) is located in the first quadrant, which indicates high importance and high satisfaction. This difference in perception can cause complaints from local customers; thus, it is necessary to change the perception of the technological aspect for ease of use of mobile banking apps in consideration of the customer's position. In addition, it is necessary to allocate the resources invested in the Innovativeness (Organization) and Increase in Revenue (Economic) to Ease of Use (Technology). Originality/value - In this study, based on the HOTE framework, factors for using mobile banking apps were derived, and IPA was conducted targeting local customers (app user) and managers and staff members (app provider) of Korean banks in Vietnam. Through this, we presented the results of empirical analysis that can help Korean banks efficiently utilize limited resources and budgets.

Purpose - Consumers perceive various risks while using food service franchise stores. Food service franchise stores offer consumers not just menus, but services, physical environment, and prices, which can be perceived as risk to consumers. This means that consumer behavior in foos service franchise stores needs to be studied based on perceived risk theory. Perceived risk consists of performance risk, financial risk, social risk, psychological risk, and time risk. The purpose of this study is to investigate the effects of perceived risk on satisfaction and trust, and in turn affect loyalty. The results of this study will provide guidelines for marketers to develop strategies to reduce the perceived risk of consumers. Research design, data, methodology - In order to achieve research purposes, the authors developed several hypotheses. Data were through online survey through an online survey firm. A questionnaire survey was distributed to customers who have visited the restaurant in the past three months. The survey was conducted from March 5, 2017 to October 14, 2017. A total of 1,500 people were e-mailed and 260 were returned. A total of 245 items were used in the analysis except 15 of the questionnaire. Data was analyzed by using SPSS 21.0 and AMOS 21.0. Results - The findings of this study are as follows: First, performance risk, economic risk, and psychological risk had negative effects on satisfaction. Social and time risks did not affect on satisfaction. Performance risk and time risk had negative impact on trust. Second, economic, social, and psychological risks did not affect trust, but satisfaction had significant positive effect on trust and loyalty. Third, satisfaction had positive effect on loyalty. Conclusions - The implications of this study are as follows. First, food service franchise marketers should increase their customer loyalty by establishing a risk reduction strategy. Second, there are various risks to customers visiting the store. Therefore, marketers need to analyze the perceived risks of customers. Third, it is also necessary to eliminate the perceived risks of customers. In addition, a restaurant franchise company needs to find a reasonable way to reduce the material cost and present a reasonable menu price.

With the advancement of the internet, the use of personal information in online interactions has increased, underscoring the significance of data protection. Breaches of personal data due to unauthorized access can result in psychological and financial damage to individuals, and may even enable wide-ranging societal attacks aimed at those associated with the victims. In response to such threats, there is active research into security measures using blockchain to safeguard personal information. This study proposes a system that uses middleware and IAM (Identity and Access Management) services to protect personal information in a BaaS (Blockchain as a Service) environment where blockchain is provided via the Internet. The middleware operates on servers where IAM roles and policies are applied, authenticates users, and performs access control to allow only legitimate users to access blockchain data existing in the cloud. Additionally, to understand the impact of the proposed personal information protection method on the system, we measure the response time according to the time taken and the number of users under three assumed scenarios, and compare the proposed method and research related to personal information protection using blockchain in terms of security characteristics such as idea, type of blockchain, authentication, and confidentiality.

Physicians should be able to address health-related issues of patients and populations from a multidimensional perspective. Therefore, medical schools have a social responsibility to develop and implement curricula that enable trainees to acquire the competencies needed to improve all aspects of patient care and healthcare delivery. This study explored the concept of health systems science concept as the third pillar of medical education (the other two are basic science and clinical medicine) in the Korean context, as well as related educational needs. The theoretical foundation of health systems science is the biopsychosocial conceptual model, which emphasizes the biological, psychological, and social factors surrounding patients. We concluded that the three domains (core functional, foundational, linking) and 12 subcategories of health systems science proposed by the Association of American Medical Colleges could be applied to Korean medical education. Health systems science education must be emphasized to solve the various healthcare problems facing Korea today and to train physicians to provide medical services in line with society's needs. Introducing a health systems science curriculum will be challenging in the Korean medical environment, which has traditionally emphasized basic science and clinical medical education. Health systems science education should begin in the basic medical education phase, where physicians' professional identity is formed, and continue through graduate medical education. It is essential to understand related educational needs, develop curricular content, conduct faculty development programs, and provide financial resources for the development of an integrated curriculum.

This study started to identify the "Forward-looking" of the technology appraisal model introduced to diversify financing methods of SMEs and improve financial accessibility. The multivariate regression analysis was performed by setting the business performance(growth, profitability, and stability) of technology financing companies as dependent variables, technology appraisal items as independent variables, number of employees, age of the company, asset and the Korea Standard of Industry Classification related to firm size and industry characteristics as control variables. As a result of the analysis, the technology appraisal items did not explain the profitability of the company significantly and had a limited explanatory power on growth potential. However, in terms of stability, we confirmed that R&D capacity is a significant variable explaining the debt ratio of technology financing companies. Therefore, it is concluded that the 'Forward-looking' reflection on the growth and profitability of the company should be strengthened in the future adjustment of the technology appraisal model and the development of the technology appraisal model for investment.

The spread of smart phones provides users with a variety of services, making their lives more convenient. In particular, financial transactions can be easily made online after user authentication using a smart phone. Users easily access the service by authenticating using a PIN, but this makes them vulnerable to social engineering attacks such as spying or recording. We aim to increase security against social engineering attacks by applying the authentication method including imaginary numbers when entering a password at the door lock to smart phones. Door locks perform PIN authentication within the terminal, but in smart phones, PIN authentication is handled by the server, so there is a problem in transmitting PIN information safely. Through the proposed technique, multiple PINs containing imaginary numbers are generated and transmitted as processed values such as hash values, thereby ensuring the stability of transmission and enabling safe user authentication through a technique that allows the PIN to be entered without exposure.
