Police is an organization that provides service to the public. Police service is focusing on enforcing the law and solving the problem to improve the relationship between police and the public within the society. To accomplish their goal, police should build a better relationship with the public. In the current study, the researcher focused on factors of police service quality, community policing, fear of crime, police-citizen relationship, and the relationship among citizens. The current study used the interview methods for collecting data of 371 individuals from Seoul metro area and resulted that each factors had a causal relationship but police-citizen relationship and citizen-citizen relationship did not show the statistically significant results. Based on this study, the research provided critics and implications.

The Private Security Industry of Korea began after served security service for the United States army of 8 division. The industry grew up after establish private security regulation on December 31th of 1976. Early 1980's the industry was accelerated from bringing technical knowledge of developed nations rapidly. Also, private security was gotten into the spotlight by one of futurity industry instead public security after companies performed 86 Asian game and 88 Seoul Olympic successfully. Therefore, the industry became to increase qualitatively and quantitatively. From late 1990's the private security regulations were revised fifteen times and created about education system, bodyguard, and leader of security. 3,836 private companies and 150,030 private guards had operated until 2012. However, some of companies received administrative measure, because of the companies ran immorally. The minor companies are continuously closed down from the leader's inefficient operation. Approval standard of establishment has imperfect law. Solutions of problems are to provide high quality service, to expand company affairs, to attract specific customers through efficiency expert, to change standard of leader of security guards, to establish security education institution through the government and to intensify requirements to establish the company.

In modern society, increasingly easier access to Internet makes people want higher and more advanced services. This trend, of course, appears in the field of Security System. This study which has been performed to prove the way service quality of Security System has an influence on customer satisfaction brought the following results. First, customer satisfaction depends on social demographic characteristics. In other words, each customer satisfaction to service quality makes a difference the way he/she gains information on available facility. Usually customers showed higher satisfaction when they accepted the information from other people. Second, customer satisfaction depends on service quality itself. The effort for improvement of work efficiency or service quality in both facility itself and surroundings can make more people use and recommend the Security System without cease.

Generalized Processor Sharing(GPS) model provides instantaneous fair services to currently backlogged sessions. Since this fair service distributes server capacity to backlogged sessions in proportion to their weights, the fairness is only valid between the sessions serviced at the same time. From the long time view, however, this fair service provides different server capacity with one session or another, even if these sessions have the same weights. This paper proposes a cumulative fair service(CFS) model to provide fair server capacity to all sessions in the long time view. This model provides fair service in session Viewpoint because it distributes server capacity in proportion to the weights of sessions. The model and an algorithm referencing that model are analyzed for their properties and performances. Performance evaluations verify that the proposed algorithm provides proportional service capacity to sessions in the long time view.

The Police main roles are order maintenance, law enforcement, community service etc. Recently it is increasing service function to community that in the cource of diverse roles. This study analyze recognition and attitudes of citizens on the Policing, participation factors, relationship among many factors between independent variables and dependent variables. The research method examine theoretical literatures and survey questionnaire for empirical analysis. The spss(win) 10.0 program is using analyze the data.

텔레매틱스 분야에서 가장 널리 서비스되고 있는 내비게이션 시스템의 최신 동향은 주행중 운전자의 정보 인지를 쉽게 하도록 하는 것이다. 실감 내비게이션 기술은 운전자의 시야와 동일한 전방 영상을 카메라로부터 획득하여 운전자에게 필요한 정보를 그 위에 오버레이하여 직접 전달하는 기술이다. 이러한 실감 내비게이션을 위하여 기존 방식과는 다른 빠르고 효과적인 정보전달 방식이 필요하며, 어떤 정보를 사용자에게 어떻게 전달하느냐에 따라 다른 효과를 가져올 수 있다. 본 논문에서는 실감 내비게이션에서의 정보 표현을 위한 화면 배치, 가상객체의 디자인 안, 정보량의 적정수준 등 디자인 방향과 고려사항을 논의하고 사용자 평가에 의한 디자인 최적 대안을 제시한다.

하나의 컴퓨터 시스템은 여러 종류의 이질적인 서버들로 구성된 것으로 간주할 수 있다. 본 논문에서는 이질적 다중서버 시스템에서의 프로세스 스케줄링 기법에 대해 연구한다. 스케줄링에서는 서비스의 공정성과 시스템 성능의 두 가지 측면이 고려되어야 한다. 여기에서는 공정성을 위하여 기존의 단일 서버 시스템에서 사용되던 공정 큐잉에 기반한 스케줄링 기법을 제안한다. 또한 각 서버간의 이용률 차이를 감안한 시스템 전체 성능 향상을 위한 방법에 대해서도 고찰한다.

최근 통계에 따르면 현재 셀룰러 이동 통신 사용자는 전 세계적으로 수십 억 명에 달하고 있으며, 증가량도 매년 7%에 이른다고 한다. 무선 이동통신은 단순히 편하다는 것 이상의 의미를 지니고 있다. 범지구적인 관점에서 살펴보면 보다 많은 사람들이 무선 기술을 이용하여 인터넷에 접속하려 하고 있다. 따라서 우리가 오늘날 World Wide Web - 스트리밍 서비스, 단문 메시지, 전자상거래, P2P- 을 이용하여 얻는 모든 이득들이 무선으로 확장되고 있는 상황이다.(중략)

국내 외 IT 제품은 그 제품이 가지고 있는 안전성 및 신뢰성에 대한 검증을 통해 국가 및 공공기관에 제품 공급 및 이용 촉진을 도모하고 있다. 또한 각 국가마다 보안제품 특징과 성격에 맞는 평가라 인증을 수행하기 위한 보안성 평가 서비스를 제공하고 있으며, 시스템 평가 기준과 방법론이 개발 및 운영되고 이에 따라 캐나다에서는 정보기술보안 제품의 안전성을 사전에 검증하기 위한 제도를 시행하고 있다. 본 고에서는 캐나다의 정보기술보안 제품 사전 검증 제도에 대한 분석을 통해 국내 적용가능성에 대하여 분석한다.

This paper has studied a management system for RCST of the Satellite Multimedia Internet Service through analysing the architecture and specification of BSAN based on Digital Video Broadcasting System. In this paper, designing and implementing RCST DPM and agent system are shown. The UCD-SNMP framework served as base station for implementation of the agent. And the message protocol between RCST DPM and agent system has been also defined to provide a way for interaction.
