The mobile electronic notification service delivers notifications through mobile phone text or app-based message push to solve various problems of the paper-based mail service. And it is a service that an electronic document relay company proves to prove delivery. In order for public and administrative agencies to provide mobile electronic notification service, the user's identification information of the mobile phone number or the subscribed app is required. To overcome these limitations, ICT-regulated sandbox system was used to allow collective conversion of users' resident registration numbers into connecting information (CI). Therefore, in this paper, we propose a technical method for safe management of user CI in mobile electronic notice service, identity verification of electronic notice readers, and prevention of forgery and forgery of electronic notices. Through the proposed method, it is confirmed that the service can be activated by minimizing the adverse function of the mobile electronic notification service by securing the user's convenience and technical safety for the CI.

The reasons for cost inflation in medical insurance expenditure are classified into demand pull inflation and cost push inflation. The former includes increase in the number of beneficiaries and utilization rate, while the latter includes increase in medical insurance fee and the charges per case. This study was conducted to analyze sources of increases of expenditure in medical insurance demonstration area by the period of 1982-1987 which was earlier than national health insurance and the period of national health insurance(1988-1990). The major findings were as follows: Medical expenditure in these areas increased by 9.4%(15.1%) annually between 1982 and 1990 on the basis of costant price(current price) and for this period, the yearly average increasing rate of expenses for outpatient care[10.5%(15.8%)] was higher than that of inpatient care [7.3%(12.6%)]. Medical expenditure increased by 6.3%(8.9%) annually between 1982 and 1987, the period of medical insurance demonstration, while it increased by 10.7%(18.9%) after implementing national health insurance(1988-1990). Medical expenditure increased by 35.9%(45.9%) between 1982 and 1987. Of this increase, 115.2%(92.1%) was attributable to the increase in the frequencies of utilization per beneficiary and 61.0%(68.1%) was due to the increase in the charges per case, but the expenditure decreased by 76.2%(60.2%) due to the reduction in the number of beneficiaries. Beteen 1988 and 1990, the period of national health insurance, medical expenditure increased by 21.2%(41.4%). Of this increase, 87.5%(46.4%) was attributable to the increase in the frequencies of utilization per beneficiary and 52.4%(73.4%) was due to the increase in the charges per case, and of the increase in the charges per case, 69.6%(40.8%) was attributable to the increase in the days of visit per case. Medical expenses per person in these areas increased by 78.2%(89.0%) between 1982 and 1987. Of this increase, 76.6%(69.1%) was attributable to the increase in the frequencies of utilization per beneficiary and 23.4%(30.9%) was due to the increase in the charges per case. For this period, demand-pull factor was the major cause of the increase in medical expenses and the expenses per treatment day was the major attributable factor in cost-push inflation. Betwee 1988 and 1990, medical expenditure per person increased by 31.2%(53.1%). Of this increase, 60.8%(37.2%) was attributable to the demand-pull factor and 39.2%(62.8%) was due to the increase in the charges per case which was one of cost-push factors. In current price, the attributalbe rate of the charges per case which was one of cost-push factors was higher than that of utilization rate in the period of national health insurance as compared to the period of medical insurance demonstration. In consideration of above findings, demand-pull factor led the increase in medical expenditure between 1982 and 1987, the period of medical insurance medel trial, but after implementing national health insurance, the attributable rate of cost-push factor was increasing gradually. Thus we may conclude that for medical cost containment, it is requested to examine the new reimbursement method to control cost-push factor and service-intensity factor.

Purpose - In recent times, the international trade environment has been changing rapidly, centering on the online market. In the post-COVID-19 era, small and medium-sized trading companies are facing the problem of not being properly provided with overseas market research, market trend analysis, and trade-related information. Cloud-based digital trade is being sought as an alternative to solve these problems; however, there is a lack of research on the intention to switch to digital trade among small and medium-sized trading companies. Therefore, this study empirically analyzes the intention to switch to digital trade based on the migration theory, and through this, attempts to identify each factor that affects the intention to switch to digital trade. Design/methodology - In this study, in order to identify factors influencing intention to switch to digital trade and innovation resistance of small and medium-sized trading companies, through previous research on migration theory and the PPM (Push, Pull, Mooring) model, each variable was selected for the purpose of the study. Based on this, a research model was established for the factors affecting switching to digital trade of small and medium-sized trading companies and empirically analyzed. In addition, considering the differences in the innovation propensity and maturity of information infrastructure of trading companies as the recipients of innovation, this study analyzes the moderating effect of the mooring effect and seeks ways to establish specific strategies according to the degree. Findings - As a result of empirical analysis, the pull effect was found to have the greatest influence on intention to switch to digital trade. However, the pull factor was found to have an effect on user resistance, and it was confirmed that it was a factor simultaneously inducing positive and negative consumption behaviors among users. In addition, it was found that the higher the company's innovation propensity, the higher the pull effect's influence on the intention to switch, and analysis showed that the push effect had no influence. In addition, companies with high information infrastructure maturity were expected to have a relatively high level of intention to switch compared to companies with low information infrastructure maturity, and the difference between the two groups was found not to be statistically significant. Originality/value - This study is a timely study in that it demonstrated the effect on the switching to cloud-based digital trade for small and medium-sized trading companies and that the cloud system related to digital trade is in full swing. There are academic implications in that it revealed that the pull effect is an important factor in the intention to switch to cloud service. Practical implications were presented in that small and medium-sized trading companies suggested ways to increase the value of the cloud system for switching to digital trade and a way to increase the switching ratio by minimizing the mooring effect. In addition, the study argues that active institutional support from the government is needed to activate cloud service.

In ubiquitous computing environment, people expect services to change actively in response to the change of themselves and surrounding environment. In order to meet such expectations, the streaming service needs technologies for migrating through various devices, following the user's movement, and the technology of individualized streaming push service. In this paper, we designed and implemented U-Stream, a ubiquitous streaming service system, based on user-defined context and stream view. The system classifies contexts according to streaming service migration and allows users to define some contexts and, by doing so, provides user-oriented individualized services rather than uniform services based solely on the developers' anticipations.

Recently, the popularity of smartphones has led to a dramatic increase in the frequency of use of App(Application) services. LBS (Location-Based Service) App service adopts various methods such as push marketing and useful information by region through providing location-based service based on the location of the consumer. In particular, an enterprise or an App management company can provide necessary information to the consumer through the necessary information among the customer related knowledge information obtained by utilizing the location information of the consumer in real time. Nevertheless, since LBS is a service that can be performed only when the company obtains consent to provide location information voluntarily by the consumer, there is a case of privacy infringement due to consumers' use of personal information. The purpose of this study is to identify the characteristics of privacy related variables and the knowledge structure for consumer value formation based on the theory of privacy calculation. We also compared the characteristics of Korea with those of China in privacy issue. As a result of the analysis, it was confirmed that factors such as information utilization ability and information control ability were influential as a key factor of privacy calculation. In addition, perceived value influences the reputation of the LBS App service.
