In this paper we describe SLA metrics and software architecture for newly upcoming IP TV service. Firstly we show the general description for IP TV. This consists of brief description of IP TV, the general figure of configuration and elements of IP TV network and communication protocol stack of IP TV data transmission for deriving communication quality parameter. And we propose SLA metrics depending on quality measurement point. According to the measurement point the measurable SLA metrics are different. The total view of the IP TV SLA measurement and management architecture is shown. When the quality measurement point is the routers that consist of internet node, the IP media NMS is the quality collection system. And when the quality measurement point is the IP TV STB(Set-Top Box), the IP media collector and Quality Collection Server are the quality collection system. And we show the software block diagram of IP TV SLA processing system and the other related network management systems.

Since 1975, Korean defence quality system has been operated by adopting defence specifications, 0050-0015, 0050-0029 and 0050-0030, which were based on the American specifications, MIL-Q-9858, MIL-Q-45208 and MIL-STD-45662. The trend that the ISO certification is intensively required for the international trade, and the need for modernization of the Korean military forces, however, provide motivation to revise the defence quality system. In this study, an improved defence quality system has been proposed by the comparison study among the requirements prescribed in ISO 9000, AQAP 100 series, MIL-Q-9858.

The paper reviews briefly of the codes above, together with the effects of the successful introduction of the QMS into the shipping industry. This paper suggests a conceptual prototype for a quality management system (QMS) of seafaring labour, which itself would be a sub-system of the total quality management (TQM) system in a shipping company, on the basis of the ISM and the ISMA Codes, ISO 9002, ISO 9004, and other quality management guidelines. The QMS is essential for the survival of the Korean shipping industry. It will contribute not only to assuring the quality of crew, but also, consequently, to increasing the international competitive edge of the shipping companies in Korea.

To provide a specified power quality under electric market system is becoming an important issue for customers and utility company. However, there is no realistic infra-structure to design a power system for the specified power quality. Present electric market is operating under the economic point of view. The low price could be attractive. but the effect of low price and low power quality for the long time should be considered for the system safety. This paper presents a model which conceptualize the dynamic power quality control mechanism to minimize total cost of a society which is affected electric power quality. This model aims to produce a basic infra-structure to balance cost and quality under the electric market system.

Recently, with the increasing use of power semiconductors and microprocessors which are very sensitive to little change of power quality and power market being formed according to the reorganization of the power market, power providers and consumers show much interest in the power quality problem. This situation makes the demand creation of integrated system for power quality analysis and monitoring based on speedy and powerful functions by the growth of computer hardware and information technology, and besides advanced corporation already have created and employed power quality analysis and monitoring system. In this papers, it will be introduced that power quality database design-database is essential to integrated system-for managing effectively and confidently data from the power quality meters(PQM).

As quality becomes a primary leading factor of organizational success, various management strategies have been introduced to improve quality competitiveness. Quality competitiveness, however, is difficult to measure and numerous organizations are struggling to set realistic improvement objectives. The primary purpose of this research is to propose a systematic approach to help the practitioners develop an improvement plan for their organizational quality competitiveness. This approach employs DEA(Data Envelopment Analysis) to evaluate relative efficiency among companies which make efforts to improve their quality competitiveness. It presents an integer programming model to elicit an optimal improvement plan for meeting a target level. A decision support system is also developed for the managers to plan a sequential improvement plan based on both DEA model and the integer programming model.

Purpose - This study aimed to identify the sub-dimensions of fashion social media quality (information quality, social quality, service quality, system quality) and investigate how they affect purchase intention through fashion information use behavior (information acceptance, information diffusion). Research design, data, and methodology - Data collection was carried out twice for systematic verification of the research model. In the first data collection, the reliability and validity of research variables were verified through 238 respondents and questionnaires were revised and supplemented based on their responses. In March 2018, the final survey was conducted from 755 respondents the age of 20 to 49. Using SPSS 23.0, descriptive statistics, exploratory factor analysis, correlation analysis were performed. In order to test hypotheses, structural equational modeling technique was employed using AMOS 23.0. Results - First of all, fashion Social media quality consists of four factors including information quality, social quality, service quality and system quality. Second, fashion Social media information quality, social quality, and system quality were shown to have a positive(+) effect on information acceptance behavior, and social quality, service quality and system quality were shown to have a positive(+) effect on information diffusion behavior. It was also determined that the acceptance and diffusion behaviors of fashion information through fashion Social media had positive(+) influence on purchase intention. Conclusions - This study holds academic significance in its identification of the components of fashion Social media quality and for conducting an empirical analysis on the causal relationship between fashion information acceptance and diffusion behaviors, and purchase intention. The results of this study indicate that fashion involvement is the key factors in determining the quality of Social media, the acceptance of information through Social media, and, by extension, the purchase of fashion products. Practitioners in the fashion industry may use the findings of this study in order to build more effective Social media strategy.

Modern stage must offer to the level which the customer requests the quality of the information service to offer from the information center. We are the one view which needs new system management around the process serving this. This study accomplished theoretical review of ISO 9000 as International Quality Management System. investigated the trend for change of ISO 9000 certification systems. We analyzed the recognition level of members about the introduction of ISO 9000 quality management systems in the information center. The level up of recognition about ISO 9000 quality management system certification systems was the low in the information center. Hereafter, We grasped the subject of ISO 9000 certification systems which the introduction needs. We reviewed ISO 9000 family which the Library and Information center possible apply and presented the requirement in the library and information center with the process to need for a Quality Management System certification.

A performance evaluation model of an R&D module in the quality management system for M Company Is constructed using QFD. The company produces telecommunication devices and employs the performance evaluation model based on ISO 9000 family. However, the model has some problems, one of them is that all check items are regarded as equally important Customer requirements are gathered from internal customers and QFD is utilized to obtain weights for each check item.
