This study attempted to investigate the value consciousness of purchasing behavior and purchasing intentions of personal beauty devices for women undergoing self-behavioral therapy. To this end, a survey was conducted, and a total of 342 copies of data were analyzed. As a result, In terms of the value consciousness, purchase behavior, and repurchase intention of the individual's personal beauty device, the value consciousness was the most materialistic, and the purchase behavior was the most economical. The overall repurchase intention was M=3.73 and SD=0.80. In correlations among value consciousness, purchase behavior and repurchase intention, positive correlations were confirmed (p<0.01). In terms of the influence of value consciousness on purchase behavior (aesthetics, conformity, effectiveness), 'aesthetic-pursuit factor' was the largest. In the effects of value consciousness on the economic aspect of purchase behavior, 'materialistic factor' was the highest. Lastly, in the influence of value consciousness on reliability, 'self-esteem factor' revealed the greatest effect. Furthermore, self-esteem factors had the biggest influence on repurchase intention. The above results confirmed that value consciousness of women in self-beauty care have a positive influence on their purchase behavior and repurchase intention for personal beauty devices. It is anticipated that they would be available as important marketing data in beauty device market.

Ubiquitous computing, a new type of network environment has been generating much interest recently and has been actively studied. In ubiquitous computing, the sensor network which consists of low electric power ad-hoc network-based sensors and sensor nodes, is particularly the most important factor The sensor network serves as the mediator between ubiquitous computing and the actual environment. Related studies are focused on network . management through lightweight hardware using RFID. However, to apply these to actual environment, more practical scenarios as well as more secured studies equipped with secures and efficiency features are needed. Therefore, this study aims to build a wireless network based on PTD for multi users, which provides the largest utility in individual networks, and propose an appropriate management method. The proposed method is designed to enhance security and efficiency related to various services required in wireless networks, based on the reliable peripheral devices for users or pm. using pm, which has been applied to electronic commerce transactions in existing papers, this study also proposed an appropriate management method that is suitable for a dynamic environment and setting a temporary group to provide various services.

In this paper, a USB module with fingerprint recognition was designed as a distributed node of blockchain on distributed ID (DID, distributed ID) for user identification. This biometric-linked fingerprint recognition device was verified for the real-time authentication process of authentication transaction with FIDO(Fast IDentity Online) server. Blockchain DID-based services were proposed like as a method of individual TV rating survey, and recommending service for customized shopping channels, and crypto-currency, too. This DID based remote service can be improved by recognizing of channel-changing information through personal identification. The proposed information of production purchase can be shared by blockchain. And customized service can be provided for the utilization of purchase history in shoppingmall using distributed ID. As a result, this blockchain node-device and Samsung S10 Key-srore with FIDO service can be certified for additional transactions through various biometric authentication like fingerprint, and face recognition.
