As information asset protection is recognized as an important management factor for organizations, organizations are increasing their investments in information security(IS) policies and technologies. However, strict application of IS may cause non-compliance behavior through IS stress on employees of the organization. Accordingly, this study suggests a mechanism by which employee stress affects IS compliance intentions through self-determination, and a method to reinforce IS compliance intentions through person-organization fit. We conducted an online survey of employees working at companies that adopted IS policies and tested hypotheses using 475 samples. First, as a result of analyzing the main effects of applying the structural equation model, role stress affected IS compliance intention through self-determination. Second, as a result of analyzing the moderating effect of applying Process 3.1, personal organization fit strengthened the relationship between self-determination and IS compliance intention. The research suggests a direction for achieving internal IS goals by confirming the influence of IS stress and behavioral causes of employees.

본 논문은 IS(정보시스템)의 전략적 활용과 OIQ(조직지능지수), CIO(최고정보책임자)역할과의 관계에 대하여 실증적으로 분석하여 효과적이고 성공적인 IT투자와 운영에 관한 지침을 제시하고자 한다. IS의 전략적 활용을 가능하게 하는 요인은 다양하겠지만 OIQ와 CIO 역할을 핵심변수로 선정, IS의 전략적 활용도와 관계분석을 통해 각 요인이 가지는 가치를 제고하여 기업에서 IT투자 성과를 극대화 함은 물론 전략적으로 활용할 수 있는 실용적인 결과를 도출하는 것을 목적으로 한다. 이를 위해 국내 상장기업 수준의 대기업 및 외감기업 이상의 기업 약 70여 개사를 대상으로 설문 조사하고 SPSS 방법을 사용하여 실증분석 하였다.

This article investigates the roles the librarians can take under the rapidly changing information environment of 21st century, in order to maintain and develop the values as professionals continuously. It suggests six role models: 1) Information educator planning and implementing the user instructions in the libraries; 2) Information counselor providing humane services through counseling on reading and cooperations in research of the library users; 3) Information searcher searching and providing thc information rapidly and accurately to the users; 4) Information mediator evaluating the usefulness of the acquired information and even providing the consulting on information management; 5) Subject speaalist specialized in specific information services; 6) Cultural program planner planning and implementing the various cultural programs.

본 기고는 기업에서 지난 6년 동안 정보보호 관련업무 실무책임자로서의 경험을 토대로 어떻게 하면 보다 더 효율적이고 안정적인 정보보호활동을 수행할 수 있을까 하는 관점에서 바람직한 CSO의 역할 모델을 정리해 본 글이다. 전혀 보안에 신경을 쓰지 않아도 보안사고가 발생하지 않으면 100점짜리 보안수준이 되는 것이고, 제아무리 보안교육과 점검을 실시하고 취약점을 개선하기 위한 다양한 보안투자를 시행하더라도 보안사고가 터지는 순간, 보안수준은 순식간에 빵점짜리로 전락한다. 때문에 필자는 종종 정보보호 책임자는 안전고리를 벗겨낸 폭탄을 가슴에 품고 언제 터질지 모르는 지뢰밭에 서있는 사람이라고 역설한 바 있다. 최근 급속한 IT기술의 발전과 극심한 개인주의 성향 등으로 그 어느 때보다 보안사고의 위험성과 피해규모가 크게 증대되고 있으며, 이에 따라 기업에서 정보보호 업무 수행부서의 역할과 책임범위 역시 과거와 달리 매우 광범위하게 확장되고 있는 실정이다. 특히 우리나라는 90년대 말 IMF 당시 구조조정의 여파로 중국을 비롯한 해외 경쟁회사로 국내 기술자들이 이직함으로써 핵심 산업기술의 유출이라는 피해를 경험한 바 있다. 그런데 최근 미국에서 시작된 세계경기의 위축으로 또 한 차례의 보안사고 위험성에 크게 노출되어 있는 상황이다. 각 국의 문화 및 산업의 다양성만큼이나 수많은 위험성이 산재하고 있는 현대 사회에서 바람직한 CSO가 되기 위한 몇 가지 착안사항들에 대하여 논해 보고자 한다.

In this paper, we study to two research direction about information security in ubiquitous computing environment. First, researches on context-aware access control using user's context or environment conditions based on role-based control. Second, researches on model for access control about context information in ubiquitous computing utilizing role base access control model. Two research directions are the one of the most important point technology in that embody ubiquitous environment in the actual world.

The objectives of access control are to protect computing and communication resources from illegal use, alteration, disclosure and destruction by unauthorized users. Although Biba security model is well suited for protecting the integrity of information, it is considered too restrictive to be an access control model for commercial environments. And, Role-Based Access Control(RBAC) model, a flexible and policy-neutral security model that is being widely accepted in commercial areas, has a possibility for compromising integrity of information. In this paper, We present the role graph model which enhanced flexibility and integrity to management of many access permission. Also, In order to represent those rule and constraints clearly, formal descriptions of role assignment rule and constraints in Z language are also given.

Due to the FMD(foot-and-mouth disease), the domestic animal husbandry and related industries suffer enormous damage every year. Although various academic researches related to FMD are ongoing, engineering studies on the social effects of FMD are very limited. In this study, we propose a systematic methodology to analyze emotional responses of regular citizens on FMD using text mining techniques. The proposed system first collects data related to FMD from the tweets posted on Twitter, and then performs a polarity classification process using a deep-learning technique. Second, keywords are extracted from the tweet using LDA, which is one of the typical techniques of topic modeling, and a keyword network is constructed from the extracted keywords. Finally, we analyze the various social effects of regular citizens on FMD through keyword network. As a case study, we performed the emotional analysis experiment of regular citizens about FMD from July 2010 to December 2011 in Korea.

In this paper, we suggest a message-based communication protocol and a dynamic role assignment mechanism for efficient cooperation and teamwork of agents in computer game environments. This role assignment mechanism is a new one different from both existing static and dynamic mechanisms, in which all decisions related with role assignment are made at once in design phase or execution phase. According to our mechanism, all possible role sets are determined in design phase. Detail decisions regarding which agent takes what role, however, are made in execution phase. This mechanism for role assignment can minimize the negotiation effort in execution phase. Therefore, this mechanism is quite effective especially in real-time multiagent environments. Through experiments, we show the superiority of the new dynamic role assignment mechanism.
