This study was attempted to develop the Special Sheet Former for Hanji (Korean Traditional Paper), which could be easily used anyone who has no any special skill, and to evaluate its sheet forming characteristics. The sheet former for Hanji was designed, manufactured and tested its sheet forming features. This former was resulted in superior even basis weights and good formation of sheets without any special technological experiences, but poor consolidation according to the difficulty of web pressing during dewatering process. Sulfomethylated pulping resulted in the superior pulp with high yield and better quality compared to those of alkali and alkali-peroxide pulps. Since the pulp was so bright, there was almost no need additional bleaching.

Trusted operating systems (OS) provide the basic security mechanisms and services that allow a computer system to protect, distinguish, and separate classified data. Trusted operating systems have been developed since the early 1980s and began to receive National Security Agency (NSA) evaluation in 1984. The researches about trusted OS are proceeding over the world, and new product type using the loadable security kernel module (LSKM) or dynamic link library (DLL) is being developed. This paper proposes a special type of product using LSKM and specific conditions for operational environment should be assumed.

이 연구의 목적은 특수경비조직의 조직문화와 조직신뢰 및 조직성과의 관계를 규명하는데 있다. 이 연구는 2011년 3월 서울소재 4개소 민간경비회사의 특수경비원을 모집단으로 설정한 후 판단표집법을 이용하여 최종분석에 이용된 사례 수는 총 161명이다. 연구에 사용된 설문지는 총 42문항으로 구성되었으며, SPSSWIN 18.0을 이용하여 빈도분석, 요인분석, 신뢰도분석, 상관분석, 다중회귀분석, 경로분석 등을 실시하였다. 설문지의 신뢰도는 Cronbach's ${\alpha}$값이 .60이상으로 나타났다. 결론은 다음과 같다. 첫째, 특수경비조직의 조직문화는 조직신뢰에 영향을 미친다. 즉, 개발적, 합리적, 합의적, 위계적 문화가 활성화 되면 인지 감정적, 행동적 신뢰를 증가시킨다. 둘째, 특수경비조직의 조직문화는 조직성과에 영향을 미친다. 즉, 합리적, 합의적 문화가 활성화 되면, 직무만족은 높다. 반면, 개발적, 합의적, 위계적 문화가 활성화 되면, 조직몰입은 높다. 셋째, 특수경비조직의 조직신뢰는 조직성과에 영향을 미친다. 즉, 인지 감정적, 행동적 신뢰가 높게 작용하면, 직무만족, 조직몰입은 증대된다. 넷째, 특수경비조직의 조직문화는 조직성과에 인과적 영향을 미친다. 즉, 조직문화는 조직성과에 직접적인 영향을 미칠 뿐만 아니라, 조직신뢰의 하위 요인인 행동적 신뢰를 통하여 조직성과에 간접적인 영향을 미친다.

Since the passing of the Personal Information Act in March 2011 and its initial introduction in September, over the one year to date diverse security devices and solutions have been flowing into the market to enable observance of the relevant laws. Beginning with security consulting, corporations and institutions have focused on technology-based business in order to enable observance of those laws competitively in accordance with 6-step key procedures including proposal, materialization, introduction, construction, implementation, and execution. However there has not been any investment in human resources in the field of education such as technology education and policy education relative to the most important human resources field nor investment in professionals in the organization for the protection of personal information or in human resources for operating and managing IT infrastructure for actual entire personal information such as special sub-organizations. In this situation, as one process of attracting change from the nature of the technology-based security market toward a professional human resource-based security infrastructure market, it is necessary to conduct research into standardization modeling concerning special organizational composition and a management system for the protection of personal information.

Through previous studies, it was found that news from legacy media, including television, has an agenda-setting effect and priming effect on the perceptions and attitudes of audiences about politics and war, and that film media also has an agenda-setting effect and political priming effect on war issues. However, it is difficult to find studies on the effects of war-related TV documentaries on media audiences. Therefore, in this study, An experimental study was conducted to investigate whether there is a change in 'recognition of the importance of security', 'will for South-North Unification' and 'will to participate in war in case of emergency' for the audience who watched the KBS special <100 Days of Invasion of Ukraine, Part 1 into the Fire>. As a result of the analysis, it was found that watching a war-related TV documentary reinforced the audience's 'recognition of the importance of security' and 'will for South-North Unification'. However, it was confirmed that watching a war-related TV documentary did not strengthen the audience's will to participate in war in case of emergency.

Two-party key exchange protocol is a mechanism in which two parties communicate with each other over an insecure channel and output the same session key. A key exchange protocol that is secure against an active adversary who can control and modify the exchanged messages is called authenticated key exchange (AKE) protocol. LaMacchia, Lauter and Mityagin presented a strong security definition for public key infrastructure (PKI) based two-pass protocol, which we call the extended Canetti-Krawczyk (eCK) security model, and some researchers have provided eCK-secure AKE protocols in recent years. However, almost all protocols are provably secure in the random oracle model or rely on a special implementation technique so-called the NAXOS trick. In this paper, we present a PKI-based two-pass AKE protocol that is secure in the eCK security model. The security of the proposed protocol is proven without random oracles (under three assumptions), and does not rely on implementation techniques such as the NAXOS trick.

전자거래상의 각종 사이버 침해 사고에 대처하기 위한 네트워크 보안 제품이 보급되고 있으나, 유지 관리 면에서 보안 전문가 정도의 전문 기술력이 요구되는 관계로 기업체나 공공기관에서 보안 제품의 설치 운영의 필요성은 절실하게 느낌에도 실제 보안제품의 보급이 빠르게 이루어지지 않아 국내 각종 사이트들에 대한 보안 취약성이 심각한 실정이다. 본 논문은 이러한 전자거래 환경의 보안관리를 비전문가도 효율적으로 관리할 수 있는 데이터 무결성 분석의 자동화 도구를 설계 구현하였다.

The emergence of new technologies and devices brings a new environment in the field of cyber security. It is not easy to predict possible security threats about new environment every time without special criteria. In other words, most malicious codes often reuse malicious code that has occurred in the past, such as bypassing detection from anti-virus or including additional functions. Therefore, we are predicting the security threats that can arise in a new environment based on the history of repeated malicious code. In this paper, we classify and define not only the internal information obtained from malicious code analysis but also the features that occur during infection and attack. We propose a method to predict and manage security threats in new environment by continuously managing and extending.
