Today, Educational serious games are occupying a large portion of the serious game market but there is a lack of the quality evaluation systems for providing useful quality evaluation information about educational serious game to user or developer. Although the existing metadata management system for serious game is developed, the system had not provided a function to manage the quality evaluation information for educational serious game. Therefor the development of quality evaluation management system of educational serious game is a very important challenge. We proposed design of the system for managing a metadata and a quality evaluation for educational serious game. The advantage of our system is that the system provide a lot of reliable useful information for general users and developers, and support an easy and convenient tool to manage the metadata and quality information to managers.

배전계통의 전기품질을 평가하기 위한 중요한 요소는 여러 가지가 있으며 그 대표적인 요소로 신뢰도 지수를 들 수 있다. 신뢰도 지수란 정전이 수용가에 미치는 영향을 정전시간과 정전수용가수로 표현한 지표로 공급에 대한 비신뢰도율을 나타낸다. IEEE 위원회는 다양한 지역을 벤치마킹하여 신뢰도 지수를 정의하였다. SAIFI와 SAIDI 등과 같이 공통적으로 사용 중인 지수가 있으며 지역의 특성에 따라 다양한 지수가 사용되고 있다. 이 논문에서는 IEEE에 정의된 전기품질 신뢰도 지수의 현황을 분석하고 국내에서 사용 중인 신뢰도 지수와 상호 비교하였다.

Voice over Internet Protocol (VoIP) is currently a popular research topic as a real time voice packet transmission method. But current Internet environment do not guarantee the quality of voice when we take a side view of delay, jitter and loss. Up to now, many voice based evaluation algorithms have been used to measure speech quality of VoIP systems. However, these algorithms have the defects that their results are different according to voice samples and some algorithms can not take network environment for speech transmission path. The E-model can be used to solve the problems of these algorithms. In this paper. we introduce VoIP planning guidelines through the various analysis of E-model which can model impairments of network quality as well as VoIP equipment quality systematically, We, also, show the evaluation method and results of speech transmission quality.

오늘날 바이오 정보처리 소프트웨어의 품질은 각종 보안장치의 성능과 신뢰성을 좌우하는 중요한 요소로 자리잡고 있다. 국내의 경우, 아직 바이오 정보처리 소프트웨어에 대한 품질특성, 특히 신뢰성에 관한 품질평가와 인증이 자리잡지 못한 실정이며 평가와 인증을 위한 시험 인증체계가 구축되어 있지 않은 실정이다. 이로 인해, 바이오 정보처리 소프트웨어의 품질저하로 인한 생체인식 분야의 보안성 및 신뢰성 저하를 유발할 수 있는 문제점이 발생할 수 있다. 본 연구에서는 ISO/IEC 12119와 ISO/IEC 9126을 기반으로 바이오 정보처리 소프트웨어의 품질요구를 체계화하고 신뢰성 중심의 바이오 정보처리 소프트웨어 시험모듈과 시험모듈 적용을 위한 점검표를 구축하였다.

Today, researches on logistics service quality or supply chain management are highlighted due to intensification of competition and diversification of needs for customer service. This study have done a comparative analysis on supply chain partnership members' perception difference about importance of logistics service quality factors. It measured perception about logistics service quality which suppliers, carriers, and buyers regard as important and then conducted t-test in order to compare perception difference. It was found that quality factors of logistic service which suppliers, carriers, and buyers in supply chain partnership perceive as important were different. And disagreements among members were found in most items when market orientation and long term orientation was low while there was no difference among most members when market orientation and long term orientation was high.

Establishment of the LFQC (Liquid Fertilizer Quality Certification) system is very urgent issue for recycling livestock manure as renewable resources in Korea faced with environmental problem of manure application to land due to intensive livestock farming. In this study, we investigated relevant laws and regulations on livestock manure fertilizer, certifications of eco-friendly agricultural products, government policies on livestock manure management to establish reasonable direction of Korean LFQC (Liquid Fertilizer Quality Certification) system. As a result from this study, the liquid fertilizers in 'LFQC' system could be classified as three levels according to the usage patterns in field; 1st. Individual Farm Level (IFL), 2nd. Joint Farm Level (JFL), and 3rd. Commercial Level (CML). And finally, we found some characteristics in 'Main Level-Grading Factors' of liquid fertilizer such as fertilizing value, harmfulness, stability, uniformity, economic effect, storage potential, commercial value, functionality. Those items were considered to be the key factors for the establishment of 'LFQC' system. More research on 'Evaluation Standards' for concrete guideline and on the 'Main Level-Grading Factors' be needed to complete Korean LFQC system.

The latest biometric field have marched fast with security technology of IT. As importance of present biometrics is realized, internal and external biometrics software market is trend that is soaring. Accordingly, high reliability of biometric software and request of high quality software are enlarged. Evaluation items and criteria must be established for biometric software quality assurance. In this paper, we development the evaluation module for biometric software test based on ISO/IEC 12119 that is the standard about software quality requirement and test, and ISO/IEC 9126 that is standard about evaluation of software product, and ISO/IEC 14598-6 that is the standard about construction of the evaluation module. Constituents of biometric software products(product descriptor, user document program and data) is subject to the quality evaluation module that we developed in this paper, we can expect improvement in the quality of software by using with a standard such as ISO/IEC 9126-3 that can be used in software development process.

The purpose of this study is to compare the national quality regulation schemes among four countries, and to find out implications to Korean quality regulation system of social services. For this, this study fixed comparative criteria on national quality regulation schemes, and compared the quality regulation schemes of 4 countries such as England, United States, Singapore and Japan. By reviewing prior relevant studies, three criteria could be suggested.: the level of user centeredness, the effectiveness of regulatory enforcement and stability of operation system. All analysed nations share similarities in that they all eager to provide quality information to their service users and develop nationally acceptable quality standards of social services. On the contrary, differences are identified in the level of regulatory enforcement and establishment of independent body for national quality control. By these results, this study discussed the meaning of these findings and their implications on the development of Korean quality regulation system.

According to the evolving of IT technologies, the amount of data we are facing increasing exponentially. Thus, the technique for managing and analyzing these vast data that has emerged is a distributed processing system of big data. A quality evaluation for the existing distributed processing systems has been proceeded by the structured data environment. Thus, if we apply this to the evaluation of distributed processing systems of big data which has to focus on the analysis of the unstructured data, a precise quality assessment cannot be made. Therefore, a study of the quality evaluation model for the distributed processing systems is needed, which considers the environment of the analysis of big data. In this paper, we propose a new quality evaluation model by deriving the quality evaluation elements based on the ISO/IEC9126 which is the international standard on software quality, and defining metrics for validating the elements.

The SP quality assessments from national IT industry promotion agency of Korea(NIPA) assesses ability of software development process. And the SP quality assessments is getting popular over the nation. But, in the SP quality assessments, there is no concern about security attribute. In this paper new secure process base on ISO 27001 is proposed for the organization that is already passed SP quality assessments. This process can detect security threatening factors and gives chance to protect those factors. Furthermore, since detected security weaknesses can be used as a measurement, the system can be managed in aspect to security attribute.
