In this paper, we place the focus on suggesting a method of forecasting demand for PCS resale service with survey data in Korea. It is important for the service provider to forecast the diffusion process when designing marketing strategies and analyzing the costs and benefits. For the reason, we conduct a survey of three groups composed of non-subscribers, cellular subscribers, and PCS subscribers in order to forecast the demand according to several possible scenarios and business strategies. We consider the survey item that is measured by multiple point scales in response to a question if he would subscribe to the mobile telephone service in the future. We propose a method to forecast the size of market potential by classifying each individual into the two extreme groups, that is, yes or no. Then, by integrating survey data and historical data, we forecast the demand for PCS resale service that varies according to scenarios and strategies. From the results, we can find several implications for the provider of PCS resale service.

To implement crowdsensing system in reality, trustiness between service provider server and user is necessary. Service provider server could manipulate the evaluation of sensing data to reduce incentive. Moreover, user could send a fake sensing data to get unjust incentive. In this paper, we adopt private blockchain on crowdsensing system, and thus paid incentives and sent data are unmodifiablely recorded. It makes server and users act as watcher of each others. Through adopting smart contract, our system automates sensing data evaluation and opens to users how it works. Finally, we show the feasibility of proposing system with performance evaluation and comparison with other systems.

This study is a descriptive survey using a self-reported survey method to understand the effect of language and non-verbal communication of medical service providers on customer satisfaction through Lapport and to determine the degree of impact on Lapport by adjusting perceived service authenticity. The data collection period was from April 5 to April 30, 2021. Using the convenience sampling method, data were collected from users of medical institutions located in Busan and Gyeongsangnam-do, and a total of 306 valid questionnaires were used as statistical analysis data. The collected data were analyzed using the IBM SPSS statistics version 25.0 and AMOS 20.0 programs through a coding process. In the results of this study, it was found that the language and non-verbal communication of medical service providers influenced customer satisfaction through Lapport, and the perceived service authenticity in the relationship between each variable acts as a moderating effect. Considering that the language and non-verbal factors of the medical service provider are important in the interaction between the medical service provider and the hospital user, the medical service provider should take full account of the language and non-verbal factors and help the medical institution communicate with the hospital user.

This paper analyzes the main factors affecting user selection of a small-sum electronic payment system using survey data of 396 users. Several findings emerge. First, users consider three pillars and eight factors in adopting a new system : system features(stability, security, and flexibility), transaction cost(payment commission and settlement period), and financial capability of provider(stability of financial structure, risk management capability, and funding capability). Second, the stability of the financial structure of the system provider is the most important factor to user acceptance of a new e-payment system. Users tend to consider uncertainty risk more seriously than transaction cost. This reflects the reality that electronic payment system service industry has not fully fledged yet. Third, some moderating effects exist according to payment methods and business usages. As for payment methods, speedy settlement cycle for wired/wireless phone payment, system stability for credit card and account transfer payment, and security for advance payment means are crucial factors. As for business usages, the stability of financial structure for online game content, system stability for music and video content, proxy payment commission for e-learning content, flexibility of the payment system for digital adult content, and security for public services are decisive ones.

In Windows operating system, CSPs(Cryptographic Service Providers) are provided for offering a easy and convenient way of using an various cryptographic algorithms to applications. The applications selectively communicate with various CSPs through a set of functions known as the Crypto API(Cryptographic Application Program Interface). During this process, a secure method, accessing data using a handle, is used in order to prevent analysis of the passing parameters to function between CryptoAPI and CSPs. In this paper, our experiment which is using a novel memory traceback method proves that still there is a vulnerability of private key and secret key disclosure in spite of the secure method above-mentioned.
