It in vary difficult to guarantee the system security when security policy systems have different policy syntax in it. It means that policy data can't be transported correctly because the security negotiation could be failed. So, we have to verify the database of security policy through investigating the syntax and function of the security policy system whether wrong or not. This paper presents the parser, which is developed for the verification of security policy. The implemented SPSL parser makes offers to classify the error, to create the information of the verified security policy used for building the SPS DB and to give both the convenience of management and the flexibility of security policy.

This study purposes to analyze the configuration of CAs(Certification Authorities) and the operating policy of CAs for cross-trusted authentication services. The CA is an authority trusted by one or more users to create and assign certificates being used to user authentication in the network. In this paper, each country's law related to Electronic Commerce and the requirement of PKI(Public Key Infrastructure) components are analyzed, and the guideline to organize CA mechanism in the domestic is mentioned

Objective : This study was undertaken for discovering the characteristics of sleep in ordinary symptoms based on the Sasang Constitution. The result of this study could be helpful to understand and to identify patients such as Taeumin, Soyangin Soeumin or Taeyangin. Methods : There were 1,229 patients (529 men), who answered the questionnaire about their ordinary sleeping patterns. They were diagnosed, including their clinical Sasang Constitution, by the Sasang Constitution specialist at Bundang Oriental Hospital of Dongguk University. By applying the multinomial and binary logistic regression analysis to those collected materials, we can measure the characteristics and the influence of ordinary sleeping patterns to the dependent variable (Sasang Constitution). Results : In order of the item's influence that had decided one's constitution, between Taeumin and Soeumin, Taeumin snored frequently or well more than Soeumin, Soeumin had more dreams and more sleeping times than Taeumin, and Taeumin struggled frequently or well more than Soeumin. Between Soyangin and Soeumin, Soeumin dreams more frequently than Soyangin, Soyangin snored frequently or well more than Soeumin, and Soeumin has more sleeping times than Taeumin. Between Taeumin and Soyangin, Taeumin snored frequently or well more than Soyangin. Between Taeyangin and a group of the other constitutions, Taeyangin felt unwell after sleeping more than the other constitutions, the other constitutions awaked frequently more than Taeyangin during sleeping. Conclusion : This study will be used for identifying patients as Taeumin, Soyangin, Soeumin or Taeyangin by contrast with each other.

원자력발전소를 비롯한 여러 산업플랜트들은 복잡한 파이프 시스템들이 필수적으로 필요한데, 이러한 파이프들 중 일부 파이프들은 안전성과 중요성을 고려하여 Over-haul 기간이나 가동 중에도 반드시 안전성 검사를 수행해야한다. 이 검사에는 검사자의 작업 공간 확보 어려움과 고위험 지역에 따른 작업환경으로 인하여 로봇을 이용한 검사 방안이 요구되고 있다. 본 논문에서는 파이프 등반 로봇을 개발함에 있어 영상을 이용한 파이프 자동 파지 기술과 로봇 원격제어 기술개발에 대하여 기술한다.
