Purpose Organizations invest significant portions of their budgets in fortifying information security. Nevertheless, the security threats by employees are still at large. We discuss methods to reduce security threats that are posed by employees in organization. This study finds antecedent factors that increases or decreases employee's compliance intention. Also, the study suggests organizations' security environmental factors which influences the antecedent factors of compliance intention. Design/methodology/approach The structural equation model is then applied in order to verify this research model and hypothesis. Data were collected on 415 employees working in organizations with an implemented information security policy in South Korea. We analyzed the fitness and validity of the research model via confirmatory factor analysis in order to verify the research hypothesis, then we analyzed structural model, and derived the result. Findings The result shows that organizational commitment and peer behavior increase security compliance intention of employees, while security system anxiety decreases compliance intention. And, organization's physical security system and security communication both have influence on antecedent factors for information security compliance of employees. Our findings help organizations to establish information security strategies that enhance employee security compliance intention.

In modern society, disasters frequently occur, and the effect is getting more massive. Also, unpredictable future increases anxiety about social security. Accordingly, in order to prevent national-scale emergency from happening, it is highly required governments' role as ICT power nation and transition to disaster management system using big data applied service. Thus, e-gov necessarily acquires disaster response system in order to predict and manage disasters. Disasters are linked with some attributes of modern society in diversity, complexity and unpredictability, so various approach and remedies of them will appease the nation's anxiety upon them. For this reason, this manuscript suggests epidemics preactive warning algorithm model as a mean of reduce national anxiety on disaster using big data for social security. Also, by recognizing the importance of e-gov and analyzing problems in weak disaster management system, it suggests political implication for disaster response.

As an extreme-type crime caused by social anxiety and economic hardship, firearm accidents recently rising as a serious social problem are gradually increasing the national anxiety as people start realizing that Korea is no more a safety zone for firearm accidents. In order to improve it, the police and academia are presenting measures through the suggestion of diverse policies and also change of system. However, there are not sufficient researches in the aspect of technology while some people argue that they cannot become fundamental alternatives on top of its effectiveness issue. Thus, this study has suggested a more effective firearms safety control system in the aspect of technology.

Background : Over a thousand years of clinical preparation of Ephedrain traditional Korean medicine has confirmed effectiveness and security. Recently. Ephedra-containing herbal preparations to treat obesity are common. The aim of this study is to identify effects of Ephedra on psychological anxiety. Objectives : To determine effects of Ephedraon psychoactivity and autonomic nervous system. Methods : The study design was a double-blind randomized controlled trial. The subjects of this study were healthy adults. They were allocated to either the Ephedragroup (N =66) or the placebo group (N =32), Ephedra(8 g) or a placebo in similar opaque capsules was given twice a day for 2 weeks. Anxiety score was estimated with State-Trait Anxiety Inventory before first and after last medication. 36 of the Ephedragroup and 24 of the placebo group finished the trial and were analyzed. Paired samples T-test and independent samples T-test were applied to statistical analysis. Results : The following result was obtained: After taking Ephedra. state anxiety increased significantly. In the placebo group. both state and trait anxiety increased although significance was not reached. Conclusions : It is concluded that the intake of Ephedraplays a significant role in the increase of anxiety in healthy adults. It is suggested that anxiety level change should be considered when using Ephedra in clinics.

The biometrics information is very useful by the convenience of ownership and using. but the risk of crime of malicious re-uses and infringement of personal privacy exist because the biometrics information is impossible to change typically when the illegal interception occurred from others. therefore the importance of security on stored management of biometrics information has been increased steadily. the existing biometric authentication system has been stored only encrypted complete template at a single storage place. In this paper, we designed the Distributed Stored of Multiple Split bio_Template System that a template is divided in different ways by each user and stored in other storage places from personal information to relieve user's anxiety about the saved template and illegally leaked through restored only template to authenticate and then delete.

Currently, the leakage of internal information has emerged as one of the most significant security concerns in enterprise computing environments. Especially, damage due to internal information leakage by insiders is more serious than that by outsiders because insiders have considerable knowledge of the system's identification and password (ID&P/W), the security system, and the main location of sensitive data. Therefore, many security companies are developing internal data leakage prevention techniques such as data leakage protection (DLP), digital right management (DRM), and system access control, etc. However, these techniques cannot effectively block the leakage of internal information by insiders who have a legitimate access authorization. The security system does not easily detect cases which a legitimate insider changes, deletes, and leaks data stored on the server. Therefore, we focused on the insider as the detection target to address this security weakness. In other words, we switched the detection target from objects (internal information) to subjects (insiders). We concentrated on biometrics signals change when an insider conducts abnormal behavior. When insiders attempt to leak internal information, they appear to display abnormal emotional conditions due to tension, agitation, and anxiety, etc. These conditions can be detected by the changes of biometrics signals such as pulse, temperature, and skin conductivity, etc. We carried out experiments in two ways in order to verify the effectiveness of the emotional recognition technology based on biometrics signals. We analyzed the possibility of internal information leakage detection using an emotional recognition technology based on biometrics signals through experiments.

Credit card is means of payment used like cash in terms of function and its users have increased consistently. With development of Internet and electronic commerce a role as payment method of credit card has been growing. But as the risk which results from centralized information and online increases, credit card fraud is also growing. Card theft and loss are decreasing due to countermeasure of card companies and financial supervisory authorities, while card forge and identity theft are increasing. Recently because of frequent personal information leakage and deregulation of financial security following easy-to-use payment enforcement, customer's anxiety about card fraud is growing. And the increase of card fraud lowers trust on credit system as well as causes social costs. In this paper, the security problems of card operating system are addressed in depth and the measures such as immediate switch to IC card terminals, introduction of new security technology, supervision reinforcement of the authorities are proposed.

Resident Registration Number(RRN) has been used broadly by public institutions or civilian departments as a means of personal identification due to its effectiveness and convenience in managing the information. Recently, because of personal information leakage including resident registration number, the potential damage is increasing public anxiety. In this situation, there have been demands requiring systems that can end the link between the resident registration number and personal information. In order to solve the problem, multiple alternatives are under consideration. In this research, we will discuss limits, needs for change of the system, and the basic concepts or traits that new registration number require. Also, by comparing the alternatives being discussed, we will analyze personal information security level and the cost required for reorganizing the system to present alternative that has high effectiveness.

In 2005, Korean government created the Internet Personal Identification Number (i-PIN) for a new online personal identification system to protect citizens' personal information against criminal abuse. However, i-PINs have not been widely in use over a decade. Although many people joined the i-PIN service, its actual use rate has been low. This study intends to identify the factors necessary to boost the continuous use of i-PINs. It was shown that government support and perceived security had a positive effect on the perceived ease of use and perceived usefulness of the i-PIN, respectively. Perceived security also directly affected the continuous use intention of the i-PIN. The perceived ease of use significantly affected the perceived usefulness, but it did not affect the intention to continuously use the i-PIN. The factor that had the most significant influence on the continuous use intention of the i-PIN was perceived usefulness. To increase the i-PIN use rate, Korean government must reduce users' anxiety through strict security functions, and must attempt to help people use the i-PIN easily.
