인터넷 사용자의 증가와 이에 따른 인터넷 트래픽 증가는 현재의 인터넷 서비스의 질을 현저히 떨어뜨리고 있다. 이러한 배경에서 인터넷 망 사업자는 사용자의 증가에 따라 망을 확장해야 하는 과제가 시급히 요구되었는데 이런 요구 사항에 의해 제시된 것이 MPLS라는 L3 스위칭 기법이다. 본 논문에서는 MPLS 기술을 기반으로 하여 ATM 환경에서의 개발중인 MPLS 라우터의 일부가 되는 포워딩 엔진의 설게와 구현에 대해 기술하고자 한다.

본 논문에서는 멀티미디어 프리젠테이션 과정에서 발생할 수 있는 여러 동기화 요소를 고려한 프리젠테이션 제어 방안에 대하여 기술하였다. 효율적인 프리젠테이션을 위하여 모노 미디어의 개별적인 효과 표현과 시나리오를 기반으로 한 스케줄러, 그리고 여러 하드웨어 및 소프트웨어 관리 쓰레드 등으로부터 동기화와 직.간접적으로 관련된 이벤트를 발생시키고 이러한 이벤트를 종합적으로 관리하도록 하였다. 발생된 이벤트는 불규칙하고 동시다발적이기 때문에 발생 환경에 따라 적절하게 폐기하거나 처리의 선후관계를 다시 정의하는 등 프리젠테이션 환경에 따른 최적의 서비스 품질을 유지할 수 있도록 고려하였다.

New information communication technologies are changing our society completely, offering the government new possibilities for providing citizens and businesses with better, and more efficient E-Government services. This study analyzes the direct and indirect impact of service value, innovativeness, and users' participation level on the trust toward the Government. Results from a citizen survey indicate that service value, innovativeness, and participation positively affect the trust toward the Government, and that innovativeness has been found to affect service value as well as the level of participation. However, the moderating effect of political efficacy on the relationship between two variables(service value and participation) and trust have been found to be insignifcant. Several other findings and policy implications are also discussed.

The purpose of this study is to find the effect of restaurant brand image upon service quality, price acceptability, and revisit intention, and to propose the importance of brand image to operators and managers who manage restaurants. To accomplish the purpose of this study, sampling was taken among customers who visit six deluxe hotels and six family restaurants in Seoul. Six hundreds questionnaires were distributed to each hotel and restaurant and 487 valid samples were selected for statistical analysis. The questionnaire consists of 77 items about demographical characteristics, brand image, service quality, revisit intention, price acceptability, and spending patterns. SPSS WIN 10.0 was used for statistical analysis. A research model was built up and three null hypotheses were established. Based on theses research model and three null hypotheses, the test was conducted, and the results are as follows. Brand image has an effect upon service quality, and furthermore this can be preceding variable of service quality. Also Service quality has an effect upon price acceptability and revisit intention.

초고속 인터넷 망의 구축에 따라 정보통신 교육이 활성화에 힘입어 직.간접적으로 응용하기 위한 노력이 지속적으로 진행되어 왔다. 웹 기반 원격강의는 원거리 학습자들의 학습욕구를 자기 주도적인 학습이 되도록 전체적인 수업을 진행하므로 학습과정에서의 질의 응답을 교수자에게 면대면으로 제공하지 못하였다. 따라서 학습자가 요구한 질의 내용을 잘못 이해함에 따라 교수자가 학습과정에서의 피드백 제공을 하지 못함으로써 개인학습의 동기부여가 감소됨에 따라 흥미를 입게 되었다. 따라서, 본 논문에서는 웹 기반 서비스에 대한 체계적인 분석 및 설계를 위해 네비게이션 모델을 통해 질의 응답을 지원하는 QALT(Question Answer Learning Tool)를 설계 및 구현한다. 원격강의는 웹 상에서 기본적인 컨텐츠를 제시하고 그를 통해 수업이 진행되는 과정에서의 질의 응답의 문제점을 개선하기 위해 일다대(One-To-Many)의 서비스를 제공한다. 또한. 학습자는 교수자가 지정한 교육용 서버를 통해 텍스트 형식이 아닌 강의자료로 쓰인 문서파일에 직접 작성하여 질의 응답을 가능하게 된다. 그로 인해 교수자와 학생간의 질의 응답을 통해 상호작용을 원활하게 할 수 있는 보조학습도구로써의 사용이 증가될 것이다. 또한 서버에서의 폴더 서비스와 메일링 서비스를 통해 실시간 질의 응답이 가능함으로써 학습자는 강의파일에서 그림에 관한 질문에 효과를 볼 수 있고 교수자는 질문 받은 내용의 위치를 시각적으로 쉽게 볼 수 있으므로 빠른 응답이 가능하게 될 것이다.

To support Integrated Services in the Internet, the Internet Engineering Task Force(IETF) has developed new mechanisms. These new mechanisms include Resource Reservation Protocol(RSVP) and Integrated Services model. RSVP and Integrated Services are independent of the underlying link layer technologies and it is necessary to define the mapping of RSVP and Integrated Services specifications onto specific link layer technologies. IETF proposed a Subnet Bandwidth Manager(SBM) providing a method for mapping RSVP onto IEEE802 style networks. However, the SBM has several constraints and problems. For solving these constraints and problems, we design and implement a new Ethernet Bandwidth Manager(EBM). This paper discusses (1) new bandwidth management mechanism independent of RSVP, (2) simulation of Ethernet bandwidth to analyze the characteristics of Ethernet and accomplish Ethernet bandwidth management, (3) design and implemetation of EBM that allows Controlled-Load Service, and (4) results of our experiments on EBM.

This study aimed to develop and validate a research model to investigate how the service quality of public libraries, where a 3-dimensional service quality model was applied, impacts user satisfaction and loyalty. We collected 353 valid responses through a survey targeting public library users across 21 locations, considering various regional and library-specific characteristics. Our analysis revealed that physical environment quality (PQ), interaction quality (IQ), and outcome quality (OQ) of service quality influence user satisfaction (US). Additionally, outcome quality (OQ) of service quality impacts user loyalty (UL), and user satisfaction (US) affects user loyalty (UL). We also found that quality improvement is a leading factor for user satisfaction, user satisfaction is the primary factor of user loyalty, and the perception of service quality directly and indirectly affects user satisfaction and loyalty. We concluded that continuous research should be actively conducted to respond to the evolving needs of public library users.

This study analyzed the effect of the operation system of human resource management. First, the primary operating direction of the goal, talent selection system, and personnel management personnel management affected almost all the performance variables. More than one primary goal of personnel management in the loyalty inspired workers more than the fixed labor costs, and external recruitment of short-term hiring favored internal training scheme for long-term employment, employee training, and development in the long term more than short-term performance improvement the more weight to quality and innovation in the productivity of labor, product and services, employee-driven innovation, reduce turnover, had a positive impact on labor relations. On the other hand, the primary goal of personnel management and personnel selection methods had a positive impact on financial performance. Personnel management operating direction did not significantly affect the financial results. Second, the main type of employee utilization affected the quality of products and services, and labor relations. Trying to take advantage of temporary workers more than regular workers had a positive impact on the quality of products and services, and labor relations. Third, the operating unit of Personnel Management had an impact on the degree of innovation of products and services. Both personal achievements and the performance of the operating units had a positive impact on the degree of innovation of products and services, more than teamwork and personnel management. This study provided practical implications for verifying the effect of detailed characteristics of human resource management on financial/non-financial business performance.
