빅데이터는 초기에는 개념적인 접근으로 대용량의 데이터로 정의하기도 하였으나 지금은 데이터를 수집, 저장, 처리, 분석하여 가치 창출까지의 개념으로 확산되고, 최근에는 정확성(Veracity), 가변성(Variability), 시각화(Visualization) 개념까지 새롭게 추가되어 7V로 제시되기도 한다.

The purpose of this study is to empirically analyze the impact of library service quality on the continuous use of libraries by international students and to verify that library anxiety plays a mediator role between the two variables - 'library service quality' and 'continuous use intention'. To conduct this study, library service quality, continuous use intention, and library anxiety of 213 Chinese international students was measured and the hypothesis through structural equation modeling was verified. The result of the study suggests that library service quality has an impact on continuous use intention and that library anxiety mediates the two variables. Based on the research result, the development of library service for international students was discussed.

Paper cultural heritages in museums and libraries are deteriorated by many biological factors like as fungi, insects, bacteria and rodents and get irreversibly damaged. Especially, paper components like as cellulose, hemicellulose, lignin, pectins, tannins, proteins and mineral additives are good nourishment for microorganism. Through some studies on fungi causing the aging of paper materials, Aspergilli (about 30%) and Penicilli (more than 30%) are the most common among 300 different kinds of microorganism that caused the biological aging of paper cultural heritages in museums and libraries. At present, various treatments are attempted to control the biodeterioration by these fungi. Especially, it is focused on the control of environmental factors such as humidity, temperature and oxygen. In this study, the oxygen absorbent was used to control oxygen, one of the these favorable conditions during the biological aging of Hanji by Aspergillus versicolor and Penicillium polonicum and then the effect on prevention in aging by this treatment was investigated. In result, the oxygen absorbent treatment had the good effect on prevention in aging during the biological aging by two species of fungi.
