최근 대다수 온라인 기업들이 고객의 개인정보에 기반한 맞춤형 서비스를 제공하기 위해 노력하고 있다. 하지만 고객들은 정보 유출에 대한 우려로 개인정보 제공을 꺼리고 있는 것이 현실이다. 이에 따라 기업들은 개인정보보호 인증마크 획득, 개인정보유출 배상책임보험 가입을 통해 고객들에게 개인정보보호를 보장함으로써 신뢰를 높이고자 한다. 이에 본 연구에서는 이러한 기업의 개인정보보호 활동이 소비자 행위에 어떠한 영향을 주는지 알아보고자 한다. 가상의 시나리오를 바탕으로 한 실험 연구 결과, 기업의 개인정보보호 인증마크 획득 혹은 개인정보유출 배상책임보험 가입이 프라이버시 신뢰를 높여주는 것으로 나타났다. 그리고 개인정보보호 인증마크의 경우, 프라이버시 신뢰를 매개로 개인정보 제공의도에 긍정적인 영향을 미치는 것으로 밝혀졌다. 마지막으로 신뢰 성향이 높은(낮은) 집단의 경우에는 개인정보보호 인증마크(개인정보유출 배상책임보험)를 통해 보다 높은 신뢰가 형성되는 것으로 나타났다. 본 연구결과는 개인정보보호 인증마크와 개인정보유출 배상책임보험의 필요성을 입증함으로써 기업 경영진의 정보보호 투자 관련 의사결정에 도움을 줄 수 있을 것으로 기대한다.

패스워드 기반 인증은 2개의 개체가 사전에 패스워드를 공유하고 인증의 기초로 패스워드를 사용하는 프로토콜이다. 패스워드 인증 방식은 약한 패스워드 인증 방식과 강력한 패스워드 인증 방식이 있다. 강력한 패스워드 인증 방식 중, SPAS는 서비스 거부 공격에 안전한 프로토콜로 제안되었으나 재전송 공격에 대한 취약성을 가지고 있다. 따라서 본 논문에서는 SPAS에 대한 재전송 공격 취약성을 분석하고, 재전송 공격에 안전한 개선된 강력한 패스워드 인증 프로토콜을 제안한다.

So far, little research has been conducted into developing a QAPM (Quality Assurance Process Model) for telecommunications applications on the basis of TMN. This is the first trial of the design of TMN-based QAPM on fault management with UML. A key attribute of the QAPM is that it can easily identify current deficiencies in a legacy system on the basis of TMN architecture. Using an empirical comparison with the legacy systems of a common carrier validates the QAPM as the framework for a future mode of the operation process. The results indicate that this paper can be used to build ERP(Enterprise Resource Planning) for a telecommunications fault management solution that is one of the network management application building blocks. The future work of this paper will involve applying the QAPM to build ERP for RTE (Real Time Enterprise) fault management solution and more research on ERP design will be necessary to accomplish software reuse.

The location template matching(LTM) method is a technique of identifying an impact location on a structure, and requires a certain measure of similarity between two time signals. In general, the correlation coefficient is widely used as the measure of similarity, while the group delay based method is recently proposed to improve the accuracy of the impact localization. Another possible measure is the frequency response assurance criterion(FRAC), though this has not been applied yet. In this paper, these three different measures of similarity are examined comparatively by using experimental data in order to understand the properties of these measures of similarity. The comparative study shows that the correlation coefficient and the FRAC give almost the same information while the group delay based method gives the shape oriented information that is best suitable for the location template matching method.

차별 서비스 모델은 IP 기반 네트워크에서 서비스 품질을 제공하기 위한 새로운 구조 모델이다. RIO 는 차별 서비스 네트워크 환경에서 라우터의 큐 관리 메커니즘으로 가장 널리 적용되고 있다. 본 논문은 패킷 길이에 따른 처리율의 영향을 완화하는 개선된 RIO 메커니즘을 제안한다. 트래픽 조절 기능인 TSW 기능과 결합하여 시뮬레이션을 수행한 결과, 제안된 메커니즘은 적절히 배치된 네트워크 상황에서 패킷 길이에 무관하게 안정된 처리율을 보장하고, 대역폭의 공평한 분배를 제공하는 것으로 분석된다.

This research studied E-Biz strategy based on the types of internet shopping-mall and user group. This study classified types of internet user into suffer group, searcher group, and confusion group according to navigation characteristics. The types of internet shopping-mall were divided into total directed mall, total mediated mall, special directed mall, and special mediated mall. The empirical study revealed that the intention of purchase has positive relationship with the assurance of e-SERVQUAL. Mediated type shopping-mall had higher market share than directed type in the use of internet shopping-mall. Suffer group was the target market of total mediated shopping-mall. Users of this group considered importantly the trust of e-SERVQUAL. Searcher group targeted special mediated shopping-mall. They had significant consideration to the responsiveness of e-SERVQUAL. Confusion group targeted direct shopping-mall. These groups had important consideration to the assurance of e-SERVQUAL.

In the paper, we designed an automatic security diagnostic evaluation System(SeDES) based on a security diagnostic evaluation model(SeDEM) for an organization's security assurance. The SeDEM evaluates a security level of an organization quantitatively by a security evaluation formula which is composed of security variables and security index as applying the statistical CAEL model for evaluate risk level of banks. The SeDES has a good expandability as changing security variables according to an organization scale, characteristics and so on. And it also has a excellent usage because it inputs only numeric data got from statistical technique to security index. We can understand more a security level correctly than the existent risk assessment system because it is possible to assess quantitatively with an security grade as well as score. analysis.

Recently classroom monitoring is becoming important since the lecture is being held in the classroom and academic institutions are interested in the quality assurance. Some institutions have adopted ISO 9000 systems and constructed monitoring system through measurement, analysis and improvement. In this study quality assurance problems in academic institutions and the requirements of ISO 9001:2000 will be briefly discussed. Next we will investigate how to monitor the lecture in the classroom(in-class) using statistical process control techniques such as control charts. Then case study will be given to illustrate the technique to use appropriate statistics. Finally how to monitor the learning process during in-class and after-class will be proposed.

As more individuals and organizations participate in the complex design process of manufacturing industry, collaborative product development and management of the global supply chain have become more popular. Although the product quality concerns once focused on the manufacturing process, they are now directed at earlier stages of the design cycle where the engineering product is created as a 3D CAD model. In this paper, we describe the current state of product data quality activities in the manufacturing industry and the yardstick to measure 3D CAD data quality. Moreover we introduce a quality assurance method through the result of statistical analysis of 3D CAD models and suggest a six sigma level of CAD data quality by analyzing 76 samples provided from three Korean automotive companies.
