The purpose of this study is to analyze user satisfaction on scholarly journals and document delivery services(DDS) at foreign journal supporting center, which is founded at K University in 2007. The number of 72 users answered the quality of scholarly journals, and 69 users answered for the DDS survey. For the scholarly journal survey, up-to-date, usability, and expertness were asked, and fastness of DDS and easiness of application procedures were asked for the DDS survey. This study reveals that overall users using or visiting foreign journal supporting center are satisfied with the quality of scholarly journals and DDS.

This paper describes the results of journals usage analysis conducted at the Korea Institute of Industry & Technology Information. The study covers the photocopy usage of journals during the past 5 years from 1995 through 1999. Analysis showed that 19% of journal collection met 93% of total demands. The Analysis also provided on journal use patterns. The most frequently used subject field of journals was Chemistry and Chemical Engineering. A relationship was found between rankings of journal as measured by the photocopy data and SCI journal citation ranking, however, no relationship was found between photocopy rankings of journal and rankings of journal impact factors.

This paper describes the results of a cost-effectiveness analysis on the usage of foreign scientific and technical journals. In this study, the measure of cost-effectiveness chosen is the Cost Per Use(CPU) of a journal article. The photocopy usage data and annual subscription costs of journals subscribed by Korea Institute of Science & Technology Information were used. The results of this study illustrate that distribution of subscription cost and photocopy usage, Cost Per Use(CPU) of each journal, CPU of each subject field, etc. 80 percent of the demand for the journal was met by 40 percent of total subscription cost. A relationship was found between subscription cost and photocopy usage, however, no relationship was found between subscription cost and CPU.

Thermal reactions by infrared radiation brings about physical damage by temperature rise process or temperature drop process of the material. In this study, a measuring system was set up to measure the temperature rise of each sample by infrared radiation from light source. And the temperature rise of the samples and amount of infrared radiation by various light source were measured with varying irradiance. On the basis of the result from the test, we analyzed a functional relation between infrared and infrared radiation.

This paper presents a new anti-copying methode for hard copy documents. The approach protects the document and its content from unauthorized copying and forgeries, while using ordinary paper and ordinary printer. The paper copy is protected against copying as the photocopy version will appear differently when compared to the authorized printed original hard copy using Human Visual System. The anti-copying pattern created through pointillism with a halftone cell and a spot. The proposed method is useful for unauthorized copying and forgeries with high-resolution scanners and photocopiers.

올해로 창립 50주년을 맞은 한국제지는 건실한 성장으로 지난해 매출 4000억 원을 돌파한 인쇄용지 전문생산기업이다. 지난 1958년 설립 이래 다양한 인쇄용지를 개발하고 품질제일주의 정신으로 국내 인쇄용지 시장을 선도해 왔으며 2006년에는 고급 복사지 브랜드 '하이퍼 CC'를 출시하여 국내 복사지 시장 진화를 선도하는 등 과감한 마케팅을 시도하고 있다. 재무구조도 우수, 유보율(자본금 대비 잉여금 보유비율)이 1000% 이상에 이르는 등 안정적이고 신용도가 높은 우량기업으로 굳게 자리매김했다. 지난 2월 50주년을 맞아 한국제지는 국민기업으로서 역사에 기억될 수 있도록 창의적인 사고와 도전정신을 앞세워 새로운 50년을 준비하자고 다짐했다. 50주년 기념행사로 사진으로 보는 한국제지 발전사 50년 전시회 관람, 다과회 등 의미 있는 행사들이 진행되었으며, 노동조합의 주관으로 한마음축제가 열려 새로운 50년을 향한 힘찬 출발을 자축하기도 했다. 한국제지 창립 50주년을 맞아 사진으로 50년사를 되돌아 본다.

The concept of detection and classification of objects based on infrared camera is widely applied to military applications. While the object detection technology using infrared images has long been researched and the latest one can detect the object in sub-pixel, the object classification technology still needs more research. In this paper, we present object classification method based on measured radiant intensity of objects such as target, artillery, and missile using infrared camera. The suggested classification method was verified by radiant intensity measuring experiment using black body. Also, possible measuring errors were compensated by modelling-based correction for accurate radiant intensity measure. After measuring radiation of object, the model of radiant intensity is standardized based on theoretical background. Based on this research, the standardized model can be applied to the object classification by comparing with the actual measured radiant intensity of target, artillery, and missile.
