This study is composed of a convergence research design plan as the necessity of information security field dealing with human factors are raised. The purpose of this study is to analyze the effectiveness of the aspect of information security on the cognitive process related to security policy. The research method consisted of the cross-design of the availability dimension and the culture dimension, and the information security process was measured with information security awareness, response efficacy, compliance behavioral intention, and information security behavior. As a result of the study, the dimension of availability had a significant effect on response efficacy, and it was found that the influence of the case-based condition was greater than that of the statistics-based condition. The cultural dimension had a significant effect on information security awareness, response efficacy, compliance behavioral intention, and information security behavior, and the influence of the homogeneity condition was found to be greater than that of the diversity condition. The proposed research model was verified as a multiple mediation model reconstructed with measurement variables. In addition, the discussion describes the necessity of an information security strategy in consideration of individual factors and organizational characteristics.

Strategies have to be employed in information systems security in order to build and operate systems for information systems security in effective and structured manner. It is also essential for the entire organization to participate for successful implementation of the strategies and making them work. Current researches on information systems security strategy in organizations, however, have mainly been focused on deployment and operation of countermeasures based on strategic thinking and decision. In consequence, it is lack of research on overall frame for containing consideration factors required for moving and leading the whole enterprise for the holistic security purpose. Therefore, this paper proposes a framework for use in establishment of organization-wide information systems security strategies based on the concept of grand strategy from the traditional strategy research and on the four dimensional features of it.

The purpose of this study is to identify the effects of organizational conflict stages and job withdrawal intention of information security organizations. We applied Pondy's conflict theory and analyzed the case of information security workers in public enterprises. We found that the more information security workers emotionally accept the potential factors of organizational conflict, the higher the intention of job change of information security practitioner. On the other hand, the perception mechanism has a moderating effect of lowering the job change-out probability. The result of this study is expected that the manager of the organization will be able to utilize the conflict in the organizational direction.

Objectives : The aim of this study was to examined the mediating role of empowerment in relations to job and organizational factors, and job satisfaction and organizational commitment in hospital organizations. Methods : Job variety, clarity, significance, and fitness were examined as the job factors, and security, reward justice, and organizational support as the organizational factors. Data were collected from 8 national university hospitals with 1,289 data points used for the final analysis. Results : All the job factors were found to positively influence empowerment, as were all the organizational factors, with the exception of reward justice . As hypothesized, empowerment had significant effects on both job satisfaction and organizational commitment, and was the most influential variable of all those examined. Conclusions : In the relations to job satisfaction, empowerment completely mediated job significance, security and organizational support, and partially mediated all other variables, with the exception of reward justice. In the relations to organizational commitment, empowerment completely mediated job variety and job fitness, and partially mediated all other variables, with the exception of reward justice. The theoretical and practical implications of these results have been discussed.

Recently, the Fintech industry is growing rapidly, and mobile payment service plays a key role in this growth. The purpose of this study is to investigate factors affecting initial acceptance of mobile payment service using Technology Acceptance Model. In the research model, service-related factors such as economic efficiency and security, user-related factors such as user innovativeness and social factors such as social influence were adopted as external variables, and acceptance intention was introduced as dependent variable. Perceived usefulness and perceived ease of use were selected as mediating variables. The collected data were analyzed using SPSS Statistics v22 and Smart PLS 2.0. The results of the study are as follows. First, service-related factors such as economic efficiency and security did not affect the user acceptance intention. Second, individual innovativeness and social influence have significant effects on perceived usefulness and perceived ease of use respectively. And the perceived usefulness and perceived ease of use, which are mediators, have a significant influence on the acceptance intention of mobile payment service. The results of this study will serve as a useful guide for Fintech industries.

In this paper, a secure multilevel quadrature amplitude modulation (MQAM) scheme is proposed for the physical layer security (PLS) of the wireless communications. In the proposed scheme, each transmitted symbol's signal constellation (SC) is hopping with the control of two unique factors: amplitude distortion (AD) factor and phase hopping (PH) factor. With unknown the two factors, the eavesdropper cannot extract effective information from the received signal. We first introduce a security metric, referred to as secrecy gain, and drive a lower bound on the gain that the secrecy capacity can be improved. Then, we investigate the relationship among the secrecy gain, the signal to noise power ratios (SNRs) of the main and wiretap channels, and the secrecy capacity. Next, we analyze the security of the proposed scheme, and the results indicate that the secrecy capacity is improved by our scheme. Specifically, a positive secrecy capacity is always obtained, whether the quality of the main channel is better than that of the wiretap channel or not. Finally, the numerical results are provided to prove the analytical work, which further suggests the security of the proposed scheme.
