The purpose of this study was to design an extensive evaluation model for the quality of web-based database and to make a comparative analysis of People's awareness of the importance of assessment indices. The evaluation standard developed in this study was constituted by 19 indices and 45 elements in three different areas, including data, service and effectiveness. And a survey was conducted on database experts and nonprofessional users to find out their awareness of the importance of web-based database evaluation elements, and the findings of the study might contribute to laying the foundation for expediting more in-depth research efforts in the future.

Recently, various approaches to recommendation systems have been studied in terms of the quality of recommendation system. A recommender system basically aims to provide personalized recommendations to users for specific items. Most of these systems always recommend the most relevant items of users or items. Traditionally, the evaluation of recommender system quality has focused on the various predictive accuracy metrics of these. However, recommender system must be not only accurate but also useful to users. User satisfaction with recommender systems as an evaluation criterion of recommender system is related not only to how accurately the system recommends but also to how much it supports the user's decision making. In particular, highly serendipitous recommendation would help a user to find a surprising and interesting item. Serendipity in this study is defined as a measure of the extent to which the recommended items are both attractive and surprising to the users. Therefore, this paper proposes an application of serendipity measure to recommender systems to evaluate the performance of recommender systems in terms of recommendation system quality. In this study we define relevant or attractive unexpectedness as serendipity measure for assessing recommendation systems. That is, serendipity measure is evaluated as the measure indicating how the recommender system can find unexpected and useful items for users. Our experimental results show that highly serendipitous recommendation such as item-based collaborative filtering method has better performance than the other recommendations, i.e. user-based collaborative filtering method in terms of recommendation system quality.

지적구조의 시각적인 표현을 위해서 오랫동안 다차원척도법이 사용되어 왔으나, 최근에는 패스파인더 네트워크와 같이 네트워크의 형태로 표현하는 방법이 확산되고 있다. 다차원척도법에 대해서는 생성된 2차원 지도의 품질을 평가하기 위한 합치도 지표로 STRESS나 RSQ를 비롯한 여러 종류가 사용되고 있는 반면, 네트워크 표현에 대해서는 마땅한 합치도 지표가 아직까지 제안되지 않았다. 이 글에서는 개체 간의 연관성을 네트워크로 표현할 경우에, 생성된 네트워크 구조를 평가하기 위한 합치도 지표로 NetRSQ를 제안하였다.

This study intends to make a comprehensive inquiry into the meaning and limitations of Discovery, and to explore how to make full use of Discovery in library cataloging. To this end, first discussed is the meaning of Discovery, which has a variety definitions. For the quality evaluation, 5 criteria were developed on the basis of literature review. Then this study conducted the quality evaluation on the basis of previously developed 5 criteria and usefulness of Discovery in library catalogs is thoroughly discussed. Based on these, the final discussion includes strategies for Korean LIS scholars and library practitioners to consider when applying Discovery as an integrated search tool.

IPTV 서비스의 지속적인 품질 유지를 위한 품질 측정 지표들의 변화가 실제 IPTV 서비스에 얼마나 큰 영향을 미치는 지에 대한 연구가 다양하게 이루어지고 있다. 그러나, 단순한 지표와 대략의 기준치를 가지고는 실제 상용 서비스에서 정확한 서비스 품질 유지에 많은 어려움을 준다. 따라서 본 논문에서는 ITU-T의 IPTV 성능을 위한 권고안에서 네트워크 성능에 따른 서비스 품질을 측정할 수 있는 지표들 중 패킷의 비순차적인 도착이 실제 IPTV 서비스에 어떠한 형태로 영향을 미치는지 분석하고자 한다.

고객 만족도조사 (Customer Satisfaction Index)는 기업 외부 관점에서 고객의 만족도를 조사하여 기업의 서비스 품질 개선에 기여한다. 그러나 기업 외부 관점의 고객만족도만의 서비스 평가뿐 아니라 내부 직원의 업무 평가를 통한 서비스 품질 개선도 필요하다. 내부 직원의 업무 평가는 직원 개개인의 능력까지 평가할 수 있는 COI(Customer Orientation Index)통해 이루어질 수 있다. 따라서 CSI 와 COI를 연계 분석하면 기업 외,내부 관점에서의 효과적이 서비스 품질 개선이 가능하다. 또, 고객만족을 위한 높은 서비스 품질을 유지하기 위해서는 서비스 품질 개선뿐 아니라 지속적인 관리와 모니터링도 필요한데 CSI 만으로는 한계가 있다. 이를 위해 CSI 분석 결과 도출된 핵심관리 프로세스를 지표화 하여 관리하기 위해 서비스 수준 계약서 (Service Level Agreement)에 반영하여 관리할 수 있다.

Sesamolin and sesamin in the five domestic varieties and seven of imported sesame seed were analyzed by High Performance Liquid Chromatography to evaluate quality of sesame oil. Their stability against roasting, changes of content during storage of sesame oil and differences in carry-through ratio by extracting method were also analyzed. The results indicated that the HPLC method was simple, rapid and reliable in the evaluation of sesame oil quality.

Public data refers to all data or information created by public institutions, and public information that leads to communication and cooperation among all people. Public data is an important method to lead the next generation of new industries such as artificial intelligence and smart cities, Korea is continuously ranked high in the international evaluation related to public data. However, despite the continuous efforts, the use of public data or industrial influence is insufficient. Quality issues are continuously discussed in the use of public data, but the criteria for quantitatively evaluating data are insufficient. This paper reviews indicators for public data quality evaluation and performs quantitative evaluation on selected public data. In particular, the quality of open standard data constructed and opened based on public data management guidelines is examined to determine whether government guidelines are appropriate. The data quality assessment includes the metadata and data values of open standard data, and is reviewed based on completeness and accuracy indicators. Based on the data analysis results, this paper proposes policy and technical measures for quality improvement.

The academic research on data governance is still in its infancy and focused on the definition of concept and components. However, we need to study of evaluation on data governance to help make decision of establishment. The purpose of this paper is to develop of attribute index in data governance framework. Therefore, in this paper, we used RGT (repertory grid technique) and Laddering techniques for experts interview and survey for validation of disinterested third party experts and analysis statistically. We completed data governance attribute index which is composed of data compliance area including 8 components, data quality area including 16 components and data organization area including 7 components. Moreover, the evaluation attributes is prioritized and ranked using the AHP. As a result of the study, this paper can be used for the base line data in introducing and operating data governance in an IT company.
