Remote sensing science is a rapidly growing field of Earth sciences. Since emergence and to present day, an extensive literature has evolved which traces the wide application of remote sensing in human activities. According to the ISI Web of Science in the 1975-2005 time span more then 20,000 papers were published on remote sensing. The number of papers grew exponentially with doubling period of about 6 years. Notwithstanding all specialized proceedings, there is a lot more remote sensing papers published in a vast list of source titles (up to 350 proceedings). Only 25% of retrieved papers are published in 10 proceedings which ISI assigns to subject category of remote sensing. In 2005 all these proceedings published 1291 articles and received cca 24,000 citations. Average impact factor of the proceedings is equal to 1.181 and average cited half-life is 7.1. It means that an average paper in remote sensing proceedings is cited more then once per year and half of citations the paper receive within the next 7 years after publication. The time line of remote sensing periodicals issued in 1927-1995 shows an exponential growth with doubling period about 15 years. After 1995 there is a prominent deviation from the exponential curve which shows the demand saturation for specialized proceedings. The features revealed are discussed in terms of dynamics and impact of remote sensing in current Earth sciences development.

Obejectives : The purpose of this study was to analyze the papers from 2015 to 2019 to identify trends in gastrointestinal studies in Korean medicine. Methods : The search for related papers was conducted in 10 oriental medicine journals that were actively reported and published, easy to search using the Internet, and freely accessible to researchers. Results : There were many studies related to the stomach, and in particular, there were many papers confirming the effectiveness of Korean medicine treatment for functional digestion, hypersensitive intestinal syndrome, and gastrointestinal reflux diseases. It is regrettable that only about 60 papers of research on gastrointestinal diseases have been published in 10 journals over the past five years of research on gastrointestinal diseases. Conclusions : These results suggest that the need to promote practical research on functional gastrointestinal disorders should be evaluated higher in the Korean medical community, and the development of gastrointestinal-related treatments for Korean medicine can improve the quality of life for all of us.

A review on the papers published in the Korean Journal of Solar Energy between 2000 and 2002 has been done. Focus has been put on current status of research in the aspect of Insolation. Solar Collector and Storage System, Solar Heating and Cooling System, Solar Cell and Lighting System, Active and Passive Solar Building, Heat Transfer in Solar Energy and Natural Energy. The conclusions are as follows. 1) Many studies on Insolation were conducted to optimize the usage of Solar Energy. 2) A review of the recent studies on solar thermal shows that there were many papers on solar collector and storage system. However, studies on the HVAC system using solar energy were relatively insufficient. 3) To produce high efficient solar cell. various experimental and numerical papers were published. However studies on control system, solar cell and lighting were seemed to be insufficient. 4) Studies on using solar energy in passive solar buildings were widely carried out, however, studies based on synthetic analysis of buildings and BIPV were insufficient. 5) Studies on heat transfer were mainly about heat exchanger, performance of heat pipe and multi air conditioner. 6) Studies on energy resources except for solar energy, such as hydraulic power and wind power etc. were very few.

In order to review the studies related to the facial pain by acupuncture, we have referred to a PubMed site by using MeSH searching word of "facial pain and acupuncture". 12 journals with 20 papers were reported on the facial pain and acupuncture. Among them, 4 papers were appeared in Am J Chin Med, 3 in Acupunct Electrother Res, 2 in Br. Dent J, J Orofac Pain and Swed Dent J respectively, and 1 in 7 journals respectively. According to the classification of the patterns, 15 papers were done by clinical studies, 2 by review and meta-analysis respectively, and 1 by experimental study. TMD was the most disease that related to facial pain and CMD, neurogenic facial pain (trigeminal neuralgia, postherpetic pain), dental pain and MPS were also appeared. Most of the studies didn't mention the acupuncture points, L14 Habkok in 4 papers and ST36 Chogsamni in a paper were only mentioned. Various modalities were applied in the trials such as classical acupuncture, electroacupuncture, TENS, SSP and auricular acupuncture. By the above results, we concluded that various acupuncture techniques are used with effectiveness on the facial pain. It would be needed further research on the acupuncture point specific and therapeutic techniques as well.

The accelerated aging characteristics of electroconductive papers manufactured with a mixture of carbon fiber were investigated by heating in dry oven. By accelerated aging time, the tensile strength, tensile stretch of the papers were decreased more slowly with increase of carbon fiber content, but the electrical conductivity was more rapidly decreased in case of high carbon fiber content. The weight loss of papers by thermal analysis were reduced as increasing the carbon fiber content. These results were indicated that the electrical conductivity of carbon fiber was diminished easily by heat aging, but thermal characteristic of carbon fiber was much better than that of wood pulp.

To develop paper coating technology for preventing print mottling, which is recognized as the most common printing problems in using coated papers, ink absorption properties of various coated papers were examined by employing K 8T N and Croda ink absorption tests. The influences of pigment compositions, coat weights and drying methods on these ink absorption properties were examined, and then the variations of ink absorption ratio were analyzed and discussed. It is demonstrated that the variation of Croda ink absorption ratio induced by coat weight variation can be utilized most succesfully to predict print mottling propensity of coating formulations. A systematic analysis approach was suggested that can be employed in the development of the most desirable coating color formulation to achieve target optical properties with the least print mottling.

To understand the research trend of environmental education(EE) during last two decades, we analyzed a total of 801 research papers published from 1990 to 2008, 418 research papers from "Hwankyungkyouk" and 393 research papers from "The Journal of Environmental Education(JEE)", respectively. The majority of the authors in both journals majored in EE, followed by authors of science education major in "Hwankyungkyouk" and authors of social science major in JEE. In both journals, more researches were data-collected by quantitative method rather than qualitative method. In particular, the ratio of researches by qualitative method have been dramatically increased since the mid 1990s. The significance test was less used in Korean EE researches than those in JEE. In both journals, more EE researches for elementary and secondary school students were accomplished, which tended to be more salient in Korea. The result of the analysis of 119 EE programs in both journals proposed that EE program needs to be developed more diversely in content as well as in educational method.
