Internet/Intranet has been continuously enhanced by new emerging IP technologies such as differentiate service(DiffServ), IPSec(IP Security) and MPLS(Multi-protocol Label Switching) traffic engineering. According to the increased demands of various real-time multimedia services, ISP(Internet Service Provider) should provide enhanced end-to-end QoS(quality of service) and security features. Therefore, Internet and Intranet need the management functionality of sophisticated traffic engineering functions. In this paper, we design and implement the performance management functionality for the guaranteed end-to-end QoS provisioning on MPLS-based VPLS(Virtual Private LAN Service). We propose VPLS OAM(Operation, Administration and Maintenance) for efficient performance management. We focus on a scheme of QoS management and measurement of QoS parameters(such as delay, jitter, loss, etc.) using VPLS OAM functions. The proposed performance management system also supports performance tuning to enhance the provided QoS by re-adjusting the bandwidth of LSPs for VPLS. We present the experimental results of performance monitoring and analysis using a network simulator.

웹 서비스와 웹 프로세스(Web Processes)는 다양한 시스템 상에서 이종의 소프트웨어 컴포넌트들을 효과적으로 통합할 수 있는 기술이다. 웹 서비스의 활용이 증대함에 따라 성능(performance), 비용(cost) 등 005(Quality of Service)는 서비스 제공자들 간의 차별화를 위한 요건으로 그 중요성이 증가하고 있다. 본 논문에서는 웹 서비스 성능 분석 도구인 sPAC(Web Service Performance Analysis Center)을 소개하여, 웹 서비스 조합시 성능의 만족 여부를 미리 고려할 수 있음을 보인다. sPAC은 1) 그래픽 기반 웹 프로세스 구성 환경을 제공, 2) 경부하(light load) 조건에서의 성능 테스트를 위해 웹 서비스를 호출, 3) 웹 프로세스에 대한 시뮬레이션 모델을 자동 생성 하여, 과부하(heavy load) 조건에서 시뮬레이션 기반의 성능 분석 수행, 4) 웹 서비스의 성능 분석 결과와 평가 데이터의 보고서 생성을 제공한다.

본 연구에서는 서비스산업별 서비스본질과 직무성과와의 영향 관계를 확인하고, 인구통계학적 특성에 따라 서비스본질과 직무성과간의 영향관계에 차이가 있는지를 검증하고 그 결과를 논의하였다. 서비스본질인 관계성, 상호작용성, 수평성, 조화성의 증대가 직무성과의 향상에 영향을 미치는지 분석하였다. 또한 OECD의 서비스산업 분류를 반영하여 대표적 서비스산업 유형에 대해 서비스본질과 직무성과간의 관계를 분석하였다. 실증분석을 통해 도출된 본 연구의 결과는 다음과 같다. 먼저 서비스본질과 직무성과와의 영향 관계를 분석한 결과, 서비스본질의 상호작용성, 수평성, 조화성이 직무성과에 정(+)의 영향을 미쳤으나, 관계성과 직무성과와의 영향 가설은 기각되었다. 한편 대표적 서비스산업별로 서비스본질이 직무성과에 미치는 영향 관계를 분석한 결과, 운수업에서는 상호작용성과 조화성이 직무성과에 정(+)의 영향을 미쳤으며, 관계성과 수평성은 직무성과에 영향을 미치지 못하는 것으로 나타났다. 금융·보험업에서는 수평성과 상호작용성이 직무성과에 정(+)의 영향을 미쳤지만, 조화성과 관계성은 직무성과에 유의미한 영향을 미치지 못하는 것으로 나타났다. 숙박·음식업에서는 상호작용성과 수평성 및 조화성이 직무성과에 정(+)의 영향을 미쳤지만, 관계성은 영향을 미치지 못하였다. 의료·보건업에서는 상호작용성과 수평성이 직무성과에 정(+)의 영향을 미쳤지만, 관계성과 조화성은 직무성과에 영향을 미치지 못하는 것으로 나타났다. 인구통계학적 특성에 의한 분석의 경우, 금융·보험업에서 나이에 따라 상호작용성과 조화성에서 유의한 차이를 보였지만, 근속연수에 따라서는 수평성만이 차이를 보였다. 숙박·음식업에서는 근속연수에 따라 수평성만이 차이를 보였다. 의료·보건서비스업에서는 근속연수에 따라 관계성, 수평성, 조화성에서 차이를 보였으며, 결혼여부에서는 수평성에서만 유의한 차이가 나타났다. 향후 전체 산업군에 대해 국가별 비교 연구가 필요하다.

In B2B e-Commerce market, many companies used in B2B e-Commerce Guarantee Service. Guarantee service raised the stability of collect debts for seller, and made purchase fund for buyer. In 2001, The first year of implementation, B2B e-Commerce Guarantee Cost was just a 19 billion, but in 2008 was significantly increased a 3 trillion 982 billion. In previous studies, however, there was no research on performance management. This study focus on design of KPI weighting for measuring performance of B2B e-Commerce Guarantee Intermediary Service. Through analysis for 'B2B e-Commerce Guarantee Intermediary Service', the study selected KPI and made the KPI weighing. the process of designing a KPI weighting is 5 phase. This study suggests the standard of measuring performance and guidelines on the focus management of KPI in B2B e-Commerce Guarantee Service.

The purposes of this study were to assess the importance and performance level of nutrition service in views of industrial employees and to explore the ways to improve the nutrition service quality. A survey of industrial foodservice operations located in Korea was undertaken and detailed information was collected from each, including surveys of 994 industrial employees. Statistical data was analysed by SAS PC 6.04 for descriptive analysis, t-test, and analysis of variance. The whole industrial employees assessed the importance and performance of the dieticians' role on nutrition service as '4.03' and '3.32' out of 5 respectively, which suggests that the industrial nutrition service needs to be improved. The variables which received higher scores than the average mean were safe meal provision, sanitation management and equipment & facilities management, whereas the score of individual nutrition counselling was low compared to other variables of nutrition service. The groups who scored low performance were characterized by labor work, experience with less than 10 years, single, aged below 29 years old, and female.

Purpose: The purpose of this study is to suggest a key quality factor affecting user satisfaction based on quality attribute of weather information system and additionally, a managerial implication for activating weather information service market by analyzing causal relevance between weather information system and business performance. Methods: As its method, a causal relevance of quality factor of weather information system affecting satisfaction and business performance was analyzed by using structural equation model. An enterprise utilized in analysis sample performed a survey by targeting 186 distribution/logistics and general manufacturing company. Results: It was revealed that information, service quality of weather information system exerted a significant influence on user satisfaction and it did not take a significant influence on business performance in terms of quality of information, system and service. A significant relevance between user satisfaction and business performance was strong supported. Finally, it was revealed that utilization level of weather information system had a moderating effect on business performance. Conclusion: Domestic weather information system mainly focused on information utilization based weather information system and additional service level utilizing weather information is very low in practical terms. Therefore, in order to expand domestic weather related service market, systematic market expansion strategy of providing corporate customized service and case enlargement would be required.

Cloud service has the characteristic that it must be always available and that it must be able to respond immediately to user requests. This study suggests a method for constructing a proactive and autonomous quality and performance management system to meet these characteristics of cloud services. To this end, we identify quantitative measurement factors for cloud service quality and performance management, define a structure for applying a time series framework to cloud service application quality and performance management for proactive management, and then use big data and artificial intelligence for autonomous management. The flow of data processing and the configuration and flow of big data and artificial intelligence platforms were defined to combine intelligent technologies. In addition, the effectiveness was confirmed by applying it to the cloud service quality and performance management system through a case study. Using the methodology presented in this study, it is possible to improve the service management system that has been managed artificially and retrospectively through various convergence. However, since it requires the collection, processing, and processing of various types of data, it also has limitations in that data standardization must be prioritized in each technology and industry.
