본 연구에서는 지질자원 분야 연구개발 수월성을 제시할 수 있는 평가방법인 계량서지학(Bibliometrics)의 SCI논문 분석을 통해 질적평가 지표를 제시하고, 이를 KIGAM의 6개 세계수준 후보 연구실의 기술수준 분석에 적용했다. Heo et al. (2008), Cho (2013)에서 제시되었던 표준화된 순위보정 영향력 지수(mrnIF)를 연구수월성 지표로 활용하였다. 2012년 편당 IF는 희유자원활용 분야 KIGAM 연구실이 가장 높았으나 순위(position) 지수 및 표준화된 순위보정 영향력 지수(mrnIF)는 지하수(최고순위 적용 position/mrnIF), 자원탐사개발(평균순위 적용 position/mrnIF) 분야가 제일 높게 나타났다. 시계열 분석 결과 표준화된 순위보정 영향력 지수(mrnIF)는 지하수 분야 연구실이 2009년, 2011년 실적이 월등이 좋으나 타년도의 경우 도시광산 및 자원탐사개발 분야 연구실이 우수한 실적을 보이는 것을 알 수 있다. 수월성 지표로 전체 게재논문 중 표준화된 순위보정 영향력 지수(mrnIF)가 80 이상인 비율 및 90 이상인 비율로 비교한 결과, 2011년의 경우 지하수 분야 연구실이 가장 우수하였으나 다른 연도의 경우 지표별로 다른 순위를 보여 가장 우수하다고 보기 어려웠다. Cho (2013)의 최고등급 연구수월성 지표인 90 이상 논문 비율 20% 이상을 도시광산 분야 연구실이 만족하고 있으며 지하수 분야 연구실은 평균순위를 적용한 2010년을 제외하고 만족하고 있었다. 이와 같이 양적인 논문 수 뿐 만 아니라 논문의 질적 분석을 통해 해당 연구실의 기술수준을 비교할 수 있었다. 세계 수준의 연구실이 되기 위해서는 양적인 SCI 논문 수의 확대 뿐 만 아니라 논문의 질적 향상을 위해 노력해야 할 것이다.

Paper is easily damaged by physical and chemical deterioration under several factors. Damaged paper cultural heritage is usually restored by Lining. A traditional method of Lining is attaching the lining paper behind the original paper cultural heritage using starch and water. It supports the weakened quality of paper. In Japan, paper cultural heritage is restored with "Washi" which is made from mixture of Paper mulberry and Japanese cedar. In the west, the lining paper made from Paper mulberry, which has extraordinary excellent conservativeness, is usually used as a restoration material for paper. But Japanese Washi has dominated the demand for restoration materials as the most preferred restoration paper, and most kinds of paper made from Paper mullbery have been called as 'Japanese paper'. Result showed that the strength of the Korean lining papers was generally higher than that of the Japanese ones. As a result from measuring the rate of dimensional change after water-immersion and drying, sample B of the Korean lining papers and sample E of the Japanese lining papers showed the highest stability.

Different papers such as toilet and towel tissue, newsprint and copy paper made from reclaimed fibres were characterized using UV-VIS reflectance and fluorescence spectroscopy. The emission properties of the extracts of the papers were also evaluated. Photochemical irradiation at ambient temperatures, and thermal aging of the copy papers at 105$^{\circ}C$ and 150$^{\circ}C$ were performed. Post-colour numbers (PC) were calculated from the reflectance values measured from the corresponding UV-VIS reflectance spectra. Light absorption coefficient spectra were calculated before and after irradiation, and the changes in absorption coefficient were related to the content of chromophores in the papers. Photochemical and thermal discolouration of the copy papers, similar to that of virgin fibres, was readily observed. The influence of changes in the concentrations of fluorescent brightening agents and dyes on the spectral properties was also assessed. Photostabilization studies of the copy papers were performed with the use of polymer additives polyethylene glycol (PEG) and polytetrahydrofuran (PTHF).

Objectives: Automated audiometry provides an opportunity to do audiometry when there is no direct access to a clinical audiologist. This approach will help to use hearing services and resources efficiently. The purpose of this study was to review studies related to automated audiometry by focusing on the implementation of an audiometer, the use of transducers and evaluation methods. Methods: This review study was conducted in 2017. The papers related to the design and implementation of automated audiometry were searched in the following databases: Science Direct, Web of Science, PubMed, and Scopus. The time frame for the papers was between January 1, 2010 and August 31, 2017. Initially, 143 papers were found, and after screening, the number of papers was reduced to 16. Results: The findings showed that the implementation methods were categorized into the use of software (7 papers), hardware (3 papers) and smartphones/tablets (6 papers). The used transducers were a variety of earphones and bone vibrators. Different evaluation methods were used to evaluate the accuracy and the reliability of the diagnoses. However, in most studies, no significant difference was found between automated and traditional audiometry. Conclusions: It seems that automated audiometry produces the same results compared with traditional audiometry. However, the main advantages of this method; namely, saving costs and increased accessibility to hearing services, can lead to a faster diagnosis of hearing impairment, especially in poor areas.
