정보통신기술이 발전함에 따라 시스템 보안의 중요성이 점점 높아지고 있다. 이어 따라 내부자의 불법적인 시스템 사용이나 외부 침입자애 의한 중요 정보의 유출 및 조작을 알아내는 침입탐지시스템에 대한 연구가 활발히 이루어지고 있다. 침입탐지시스템에서는 사용자가 입력한 명령어, 네트워크 패킷, 시스템 호출 감사자료, 시스템 사용시간 등의 다양한 척도를 사용하여 침입여부를 결정하는데 사용하는 척도와 모델링 방법에 따라 취약점이 존재하여 탐지하지 못하는 침입이 있다. 본 논문에서는 단일척도 침입탐지 시스템의 취약점을 보안하기 위해 시스템 호출, 프로세스의 자원점유율, 파일접근이벤트의 세 가지 척도를 각각 최적의 방법으로 모델링 한 후 결합하는 침입탐지 방법을 제안하고 실험을 통해 그 가능성을 보인다.

This qualitative study is designed to explore parents' experiences with their children handicapped with restricted growth. The parents' unique reality and its essential meanings are elicited through in-depth interviews enabling to reflect the insider's perspective. "From the child unable to grow to the child able to grow" is identified as the main theme penetrating through the participants'parenting experiences unique to their reality. Embracing the shock and the disappointment related to their children 'unable to grow', they thrive to make their children able to grow. However, they eventually accept their children's handicap, in spite of never doing it easily, by getting confronted with the limits of making their children grow in stature, and the social stigma and the difficulty their children experience. Therefore, they get to take alternative perspectives not focusing on their children's stature unable to grow but on psycho-social growth able to grow. Social welfare plans to support the handicapped with restricted growth and their parents are suggested.

This paper attempts to verify that the economic gap between the workers in (large) firms with unions and those in (small and medium size) firms with no unions has recently been widened rapidly. A comparison of the wages of the workers belonging to the business establishments with and without trade union shows that the union premium has increased very sharply since 1997, after a relatively long periods with little changes. Also found is that union sector has witnessed a sharper decline in the share of the new entrants among workers as well as a faster increase of the average tenure of workers. These all indicate that the trade unions have forced a market equilibrium to move farther away from the competitive equilibrium in recent years.

Investment of organization in information security is increasing, but information security threats within the organization are not decreasing. The purpose of this study is to suggest a direction to increase the information security compliance intention of employees. In detail, the study presents the positive effects of security motivation and organization trust on the information security compliance intention, and presents the moderating effect of work promotion focus. Research model and hypothesis verification are confirmed through structural equation modeling and the study conducted a questionnaire technique to the employees of the organization applying the information security policy for quantitative verification. As a result, information security punishment and value congruence had a positive affect on the compliance intention by mediating organization trust. In addition, work promotion focus had a moderating effect on the positive relationship between the precedent factors on the compliance intention. The research has academic and practical implications from the viewpoint of presenting the factors of the organization's efforts to improve the level of information security compliance by insiders.

Organizations depend on smart working environments, such as mobile networks. This development motivates companies to focus on information security. Information leakage negatively affects companies. To address this issue, management and information security researchers focus on compliance of employees with information security policies. Countermeasures in information security are known antecedents of intention to comply information security policies. Despite the importance of this topic, research on the antecedents of information security countermeasures is scarce. The present study proposes information security intelligence as an antecedent of information security countermeasures. Information security intelligence adapted the concept of safety intelligence provided by Kirwan (2008). Information security intelligence consists of problem solving skills, social skills, and information security knowledge related to information security. Results show that problem solving skills and information security knowledge have positive effects on the awareness of employees of information security countermeasures.

Recently, remote user authentication scheme protecting user anonymity using smart card has been researched with interest increasing on user privacy. Although authentication scheme providing user anonymity using smart card had been proposed by Das et al, Chien et al. pointed out Das et al. scheme fail to provide user anonymity and proposed new scheme to overcome the problem. A remote system Kim et al. proposed a scheme which is traceable about malicious user with protecting user anonymity. In this paper, we point out that Kim et a1. scheme fail to provide user anonymity and propose a scheme for some problems Kim et al. scheme has. And then we analysis our scheme on cryptophic security and efficiency with Kim scheme.

Awareness that smartphones can be used as tools for criminal activity is prevalent in many organizations, but the functionally smartphone-like smartwatch's potential as a criminal tool is being overlooked. Considering this situation, this research verifies the possibility of information leakage through an insider's smartwatch in a situation where smartphones are controlled by security regulations and technologies, but smart watch are not. By analyzing information related application usage and Wi-Fi connection generated in the smartwatch during the verification process, forensic information and limitations are identified. Finally, this research proposes preventive methods to prepare for potential smartwatch-related crimes, and reconsiders awareness of the possibility of using smartwatches as criminal tools.

Socially, organizations are required to effectively manage their information resources, both in terms of acquiring information from external sources and safeguarding against potential breaches by insiders. While information security policies and technologies implemented by organizations contribute to achieving internal security, an overly complex or disorganized security structure can create uncertainty among employees. In this study, we identify factors of structural information security (IS)-related uncertainty within organizations and propose that they contribute to non-compliance. We develop a research model and hypotheses based on previous studies on the information security environment and test these hypotheses using structural equation modeling. Our findings indicate that uncertainties related to IS policy, technology, and communication decrease employees' IS role identity and their intention to comply with IS measures. By addressing these uncertainties, organizations can improve their IS environment and work towards achieving there is goals.

The elderly suicide has become a social problem, and the need for academic and practice-based knowledge for preventing elderly suicide has been addressed. Unlike previous literature focusing on identifying risk factors, this study aimed to address protective ones which help to overcome suicidal behavior among older adults. The purpose of this qualitative study was to understand how older adults get over being suicidal and get back to life, and to identify what helps them during the process. Both in-depth interviews with 35 elderly with suicide attempts and field notes were analyzed through thematic analysis. The older adults described a pathway to rediscovering a 'will to live' that was related to a 'mind's incline' and included two kinds of protective factors. Based on the findings, it addresses the implication for the elderly suicide prevention utilizing protective factors.

Recently, organizations are demanding strict information security behavior from their employees. Strict information security policies and techniques can cause information security related stress. The purpose of this study is to present the negative effects of information security related techno stress and role stress that reduce knowledge sharing behavior and person-organization fit. The survey was conducted to people working in organizations with information security policies and system, and the research hypothesis was verified by structural equation modeling using 309 samples. As a result of the study, person-organization fit had a positive effect on knowledge sharing behavior, but role stress had a negative effect. And, techno-stress negatively affected the person-organization fit. Additionally, role ambiguity had a moderating effect between person-organization fit and knowledge sharing behavior. The implications of the study were to confirm the negative effects of information security related techno stress and role stress, and to suggest directions for minimizing negative behavior of insiders.
