Oral medication is the most frequent treatment measure for follow up treatment, which is leading by childrens' parents for them. In medication for preoperational children, they tend to concentrate the result rather than the motivation or cause. So, they frequently refuse medication which has bitter taste. So this study was attempted to develop token economy program which promote children's medication and help their parents, and to evaluate its' effect to construct the experimental ground. This study was a quasi experimental study under the nonequivalent control group posttest only design. The subjects of this study were 36 children who were aged 3-6 years and admitted pediatric ward because of their respiratory disease. Token economy program was consisted of cartoon record paper with stickers which expresses the better medication is taken the more germs die, and gift was given for back up reinforcer. To evaluate this program, time for oral medication was measured to both experimental group and control group. To determine the effect of the program, the data were analyzed by the SAS 6.12 program with t-test. The results of this study were as follows: 1. Between experimental group and control group, there was no significant difference (t=-1.2411, P=0.2374). Therefore, the hypothesis of this study was rejected. In conclusion, the token economy program for follow up care didn't change the children's behavior of oral medication. But it was found that the cartoon on recording paper gave a pleasure to participated children. Parents who were in experimental group expressed their appreciation for token economy program. So it can be said that the token economy program for follow up care was effective in inducing the children's pleasure and parents' satisfaction even though it wasn't successful in experiment. If the measuring tools for token economy program was made with well planned design and high reliability, it can be improved the effectiveness of that To develope the theoretical bases of nursing care, the well planned programs and measuring tools for them should be developed.

With the recent advancement of information and communication technologies such as artificial intelligence, big data, cloud computing, and 5G, data is being produced and digitized in unprecedented amounts. As a result, data has emerged as a critical resource for the future economy, and overseas countries have been revising laws for data protection and utilization. In Korea, the 'Data 3 Act' was revised in 2020 to introduce institutional measures that classify personal information, pseudonymized information, and anonymous information for research, statistics, and preservation of public records. Among them, it is expected to increase the added value of data by combining pseudonymized personal information, and to this end, "the Expert Data Combination Agency" and "the Expert Data Agency" (hereinafter referred to as the Expert Data Processing Agency) system were introduced. In comparison to these domestic systems, we would like to analyze similar overseas systems, and it was recently confirmed that the Vermont government in the United States enacted the first "Data Broker Act" in the United States as a measure to protect personal information held by data brokers. In this study, we aim to compare and analyze the roles and functions of the "Expert Data Processing Agency" and "Data Broker," and to identify differences in designated standards, security measures, etc., in order to present ways to contribute to the activation of the data economy and enhance information protection.
