This study attempted to demonstrate the role of perceived value and trust in the relationship between mobile banking service quality and use satisfaction. A survey was conducted on customers of Mongolian banks, and an analysis was conducted based on the collected data With the development of the fintech industry, the Internet-based mobile banking market is striving to provide convenient services to consumers. The result led to the introduction of an online-oriented Internet bank that can operate 24 hours a day regardless of time and space. The characteristic of operating only with the Internet has a positive aspect of providing services quickly and conveniently, but at the same time, including concerns about security and personal information leakage. This can make you hesitate to use the service. Therefore, we attempted to find out how the quality of mobile banking service affects the perceived value and satisfaction of using trust. A survey was conducted to verify the contents of the research model and hypothesis. This is to secure data to be used for empirical analysis of research hypotheses. The survey was conducted with 124 consumers in Ulaanbaatar, the capital of Mongolia. Based on the analysis results, we understood the satisfaction of consumers using mobile banking and suggested ways for consumers to improve their actual satisfaction using mobile banking. Specifically, service quality sensitivity, security, convenience, and design had a positive effect on perceived value or trust, ultimately leading to consumer satisfaction.

The analysis and comparison on the usage of public cremation facilities located in Seoul through online reservation service of ehaneul funeral information system by area from Jan. 1, 2011 to Dec. 31, 2017 showed that among 314,877 in the number of bodies using the facilities, 225,828 (or 71.7%) belonged to Seoul citizens and 89,049 (or 28.3%) belonged to people living in other area than Seoul, such as Goyang city, Gyeonggi-do and other local governments. Therefore, there appeared that the Seoul citizens could not get the timely cremation service but instead extended the funeral service to 4 to 5 days or had to go to the remote area for cremation. This trend gets severe every year. To solve these problems, it is recommended that Seoul city government makes effort of constructing or expanding the public cremation facilities in cooperation with other local government of the area whose residents show high rate of using Seoul public cremation facilities and that Seoul city government expands or builds its own public cremation facilities in mid- and long-term. In addition, the local government of other area around Seoul needs to expand their use rate of their own (4) public cremation facilities or raise the creation fee for the residents from other areas, thus trying to dispersing and controlling the demand for the cremation.

This study seeks to provide implications for domestic-related policies through exploratory analysis research to support AI-based policy decision-making. The following should be considered when establishing an AI-based decision-making model in Korea. First, we need to understand the impact that the use of AI will have on policy and the service sector. The positive and negative impacts of AI use need to be better understood, guided by a public value perspective, and take into account the existence of different levels of governance and interests across public policy and service sectors. Second, reliability is essential for implementing innovative AI systems. In most organizations today, comprehensive AI model frameworks to enable and operationalize trust, accountability, and transparency are often insufficient or absent, with limited access to effective guidance, key practices, or government regulations. Third, the AI system is accountable. The OECD AI Principles set out five value-based principles for responsible management of trustworthy AI: inclusive growth, sustainable development and wellbeing, human-centered values and fairness values and fairness, transparency and explainability, robustness, security and safety, and accountability. Based on this, we need to build an AI-based decision-making system in Korea, and efforts should be made to build a system that can support policies by reflecting this. The limiting factor of this study is that it is an exploratory study of existing research data, and we would like to suggest future research plans by collecting opinions from experts in related fields. The expected effect of this study is analytical research on artificial intelligence-based decision-making systems, which will contribute to policy establishment and research in related fields.

The purpose of this study is to design and test a new way of public transportation route guidance system for persons with disabilities, including wheelchair users. The guidance system is smartphone app-based, using, routes that involve disabled-friendly facilities in the vicinity can be searched. A database that contains publicly available data on low-floor bus services, location and extent of disabled-friendly facilities, and suitable subways and stations, was developed for this purpose. The app uses the database to access and query the required information. A pilot study was conducted to test the effectiveness of the guidance system. It was found that the system was able to convey information about the disabled-friendly routes and related guidance information even inside subway stations, effectively. The performance of the system was compared with route guidance services that do not explicitly use data on disabled-friendly services. A notable difference was observed in the travel time estimated by this program and other guidance services. The difference was around 4 to 15 minutes. This is significant savings for persons with disabilities if they use the app and service. The study thus shows that exclusive use of disabled-friendly data in route guidance will bring more benefits for persons with disabilities.

In a cloud computing environment, a cryptographic service allows an information owner to encrypt the information and send it to a cloud server as well as to receive and decode encrypted data from the server which guarantees the confidentiality of shared information. However, if an attacker gains a coded data and has access to an encryption key via cloud server, then the server will be unable to prevent data leaks by a cloud service provider. In this paper, we proposed a key management server which does not allow an attacker to access to a coded key of the owners and prevents data leaks by a cloud service provider. A key management server provides a service where a server receives a coded public key of an information user from an owner and delivers a coded key to a user. Using a key management server proposed in this paper, we validated that the server can secure the confidentiality of an encryption key of data owners and efficiently distribute keys to data users.

It has been 3 years since the TV broadcasting industry migrated to the UHDTV broadcasting service. Theoretically UHDTV picture quality is four times better than HDTV. UHDTV broadcast has been put to practical use by domestic broadcasters, excluding public broadcasters. The resolution of UHDTV does not correspond to the standard UHDTV values, the viewer have no choice but to watch existing contents on UHDTV. Therefore this paper analyses the current broadcast technology level for the image quality improvement, and to investigate the bandwidth of UHD broadcasts. In this paper we have studied current condition of HDMI interface technology and suggesting Super MHL interface technology capable of performing a successful establishment of the new broadcasting platform in future 8K UHD broadcasts alternatively. In order to improve the UHD broadcasting, we are expecting the development change of UHD broadcasting service user experience.
