As the reduction of information exposure threats by organization insiders contributes to achieving information security(IS) goals, organizations are establishing strict IS policies applicable to insiders and increasing investment in IS systems. However, since IS incidents cause damage to an organization even by malicious information exposure by one person, psychological support for strengthening IS compliance behavior by insiders. This study aims to confirm how the uncertain organizational environment related to IS affects individual IS-related behavior. We surveyed insiders of organizations operating IS policies and tested the hypothesis using 440 samples. As a result, IS technology and communication uncertainty reduced IS voice behavior through IS prospective anxiety, and individuals' susceptibility to information influence moderated the relationship between IS technology, communication, and prospective anxiety and IS voice behavior. Our results suggest the necessity and direction of supplementing the uncertain IS environment in practice.

Aircraft accidents are characterized by a low probability of survival compared to other means of transportation, and the main causes appear to be human factors such as violation of regulations and communication. In order to activate the safety management system to prevent such accidents, an important key variable is to recognize the importance of safety culture and actively engage in safety behavior rather than simply emphasizing compliance with regulations to flight crew members. Even if there are well-established regulations, safety culture, The effectiveness varies depending on the safety atmosphere and level of safety behavior. In this study, the correlation between safety culture and safety behavior was verified through a survey of domestic flight crew members' awareness of safety culture. The results showed that fair culture and self-reporting were not activated enough to have a significant impact on safety behavior. We aim to improve the performance of the safety management system by confirming the characteristics of safety culture and safety behavior.

The purpose of the current study is to to examine the psychometric properties of the Subjective Agingwell Scale (SAS). Three hundred and forty two elders completed the SAS and the scales assessing subjective well-being, optimism, perceived control and adhering to healthy behavior. The 11-item SAS that displays good internal reliability and good fit to the three-factor model consisting of cognitive satisfaction, positive affect, and spiritual fullness. Correlational analyses with measures of subjective agingwell, subjective well-being, and optimism provide evidence for construct validity. Moreover, the results from hierarchical regression analyses show criterion-related validity of the SAS. This scale could be used in the field to measure and promote subjective agingwell.

Company strengthen various information security policy and activity in order to protect important information assets that the company has been dealing with and prevents information security accidents such as personal information spill. However, some study said these policy and activity increase employee's information security stress and still information security accidents by employees have happened so far. Therefore, this study will review preceding theories and studies used in many various fields including Information Security areas needed to explain human's behavioral intention and determinants and summarize characteristic factors that have influence on control of human's behavioral intention in the results of the above theories and studies. Secondly, this study will implement exploratory analysis on characteristic factors perceived by employees that has been stemmed from various company's information security policy and activity in order to increase employee/'s information security compliance intention under the its surrounding security circumstance. Thirdly, this study will fulfil multiple-regression analysis in order to identify cause-effect relationship between employee's perceived information security stress and employee's perceived characteristic factor. Finally, this study will explain casual relationship with same analysis methods between information security stress and information security compliance intention based on results of the survey conducted on the financial firm's employees with same analysis methods.

The unprecedented pandemic caused by the COVID-19 has led to a massive global public health campaign to slow the spread of the virus. Thus, this study examines the importance of individual's prevention behavior intention by adapting health belief model(HBM). In addition, we added social variables to understand the prevention behavior better considering the situation in which collective behaviors are important. The online survey results(N=298) showed that higher level of perceived severity, perceived susceptibility, perceived benefits, perceived peril, perceived social norms and lower level of perceived responsibility led to higher prevention behavior intention. Peril was the most influential factor among all the variables. In addition, perceived severity and social norms followed after that. Additional analysis also implied that socio-HBM model we proposed better explained the prevention behavior intention than traditional HBM.

This study was conducted by extending Ajzen's Theory of Planned Behavior(TPB) model in analyzing physician's observance behavior of National Health Insurance review standards. An extended TPB model was proposed by including 'background knowledge'and 'dorganizational commitment'in original model to predict physician's review standards observance behavior. Surveys for data collection were carried out on the physicians who were working in a general hospital, clinics, specialized hospitals, local medical centers and long term care hospitals located in Daegu and Kyoung-Buk province in Korea. Two hundreds twenty copies of questionnaires were distributed and 166 physicians responded. Data were analyzed using a structural equation model. The results show that an affirmative attitude and subjective norms have significant positive effects on physicians' behavior of observing review standards. However, the effect of perceived behavioral control on intention to behavior is not significant. The organizational commitment and background knowledge have a positive effect on the intention of observance of review standards. In conclusion, because physician's observance behaviors are affected by background knowledge and organizational commitment as well as attitudes, subjective norms, hospital managements should establish a communication system to share information on the review standards among physicians and provide appropriate measures to increase physician's organizational commitment.

This study applied the Theory of Reasoned Action by Fishbein & Ajzen(1975) as the grounded theory and adopt sanctions of the General Deterrent Theory and protection motivation of the Protection Motivation Theory as the antecedents to discuss the theoretical factors and the cases of application in the field of information security. Then, it adopted subjective norm, a variable of the Theory of Reasoned Action, as a parameter to analyze the causality of sanctions, perceived vulnerability, response cost, and self-efficacy with the intention to follow the information security policies. As a result, all of the antecedents except for sanctions had causality with the intention and subjective norm proved its mediating effect as a parameter between the antecedents and the intention.

Recently, organizations are increasing their investment to protect information resources from information security(IS) threats through the adoption of IS policies and technologies. However, IS incidents occur in a variety of ways, such as intrusions from outside the organization and exposure to the inside. Our study presented the negative effects of IS role stress on organizational insiders and suggested factors from the organizational and individual perspectives for mitigating IS role stress. We conducted a survey on employees of companies that introduced and applied IS policies to their work and tested the hypothesis using 329 samples. As a result, IS organization justice reduced IS role stress and strengthened IS positive psychological capital, thereby affecting the IS compliance intention of employees. Also, IS positive psychological capital moderated the relationship between IS stress and IS compliance intention. This study contributes to the achievement of internal IS goals by suggesting the conditions that affect the IS compliance behavior of employees in terms of the organizational environment and individual characteristics

The common features of the behavioral inhibition and the action monitoring that are considered as one of the executive functions were investigated using event-related brain potentials (ERPs) and source localization analysis. The electrophysiological correlates of behavioral inhibition and action monitoring ate analyzed when the subjects performed the Go/NoGo task. Two ERP components of behavioral inhibition termed as N200 and P300 in NoGo condition were differ from those of Go condition, that is the amplitudes of NoGo N200 and P300 are largest on the fronto-central region, which may reflect the inhibitory control of frontal lobe required in NoGo condition. The error-related negativity (ERN) observed on the fronto-central region when the subjects committed error was much larger in amplitude and faster in latency than those of the correct-related negativity (CRN), which may indicate that the signal of action monitoring is much more required for the error response. The correlation analysis for the ERP components of behavioral inhibition and action monitoring revealed the significant negative correlation among the latencies of NoGo N200 and P300 and the amplitude of ERN, which may reflects that the faster subjects inhibit response, the more monitor their own action. The close relationship between behavioral inhibition and action monitoring was also supported by the results of source localization analysis, which showed the common neural sources of NoGo N200 and ERN was anterior cingulate cortex.
