Since the authors participated in the editorial committee in October 2001, many dramatic changes have been introduced to the Journal of Korean Neurosurgical Society(JKNS). The format, the external appearance, the editorial system, and the reviewing process have been transformed with new standpoints to enhance the quality and to raise the level of JKNS. The authors reviewed papers published on JKNS in 2006 with special interest on the changes of JKNS during last five years.In total, 186 articles were published on JKNS in 2006. Because the editorial committee asked two review articles to renowned neurosurgeons, there were 184 peer-reviewed articles. Eighty seven clinical articles, eighty one case reports, seven laboratory investigations, four special articles and five technical reports were published. This distribution changed from the previous year with marginal value of statistical significance (p=0.101). The ratio of the original articles (laboratory investigations and clinical articles) decreased to 51.1% from 57.5% of 2005 but the difference was not statistically significant (p=0.222). The number of laboratory investigations significantly decreased to 7 (3.8%) from 19 (10.4%) of 2005 (p=0.014). Other changes such as number of authors per article, number of institutes which published papers on JKNS have been examined to assess the trend and/or change in characteristics of papers published on JKNS.

For the measurements of an absorbed dose using the standard dosimetry based on an absorbed dose to water the variety of factors, whether big, small, or tiny, may influence the accuracy of dosimetry. The beam quality correction factor kappa(Q, Q(0))of an ionization chamber might also be one of them. The cylindrical type of ionization chamber, the PTW30013 chamber, was chosen for this work and 9 chambers of the same type were collected from several institutes where the chamber types are used for the reference dosimetry. They were calibrated from the domestic Secondary Standard Dosimetry Laboratory with the same electrometer and cable. These calibrated chambers were used to measure absorbed doses to water in the reference condition for the photon beam of 6 MV and 10 MV and the electron beam of 12 MeV from Siemens ONCOR. The biggest difference among chambers amounts to 2.4% for the 6 MV photon beam, 0.8% for the 10 MV photon beam, and 2.4% for the 12 MeV electron beam. The big deviation in the photon of 6 MV demonstrates that if there had been no problems with the process of measurements application of the same kappa(Q, Q(0)) to the chambers used in this study might have influenced the deviation in the photon 6 MV and that how important an external audit is.

Thesedays, the computer network has become the most popular means of communicating and sharing of information. With the rapid growing of Internet usage, various kinds of medical-related Internet sites are appearing. Due to the popularity of World Wide Web, many hospitals and medical centers establish their own homepage. In Korea, the number of home pages about medicine and medical institutes is increasing. Although many medical-related sites in Korea are providing Internet services on WWW, the quality is still far behind from foreign countries. For constructing the homepage for each department in Soonchunhyang University Hospital Homepage, this paper first investigates the University Hospital's Internet Homepage. After rewiewing the homepage, the new homepage of Soonchunhyang University Hospital has een implemented. From the experience in implementing the homepage for Soonchunhyang University Hospital, this paper suggests the method to build and manage a homepage for other medical related sites.

BACKGROUND: The authors produced a new citation index of the Korean Journal of Blood Transfusion (KJBT). The index, which was developed to determine the internal impact score (IIS), could examine contributions to the KJBT according to the manuscript, author and institute. METHODS: For manuscripts published in the KJBT from Volume 1 No. 1 in 1990 to Volume 17 No. 1 in 2006, a database of the journals and their references was constructed, and an index was created. The citation index was analyzed using three indicators, the internal impact score for the manuscript (IIS-M), internal impact score for the author (IIS-A) and the internal impact score for the institute (IIS-I). RESULTS: The total number of references cited in the manuscripts was 5,392. Of these references, 498 (9.2%) were published in the KJBT. The mean IIS-M of all manuscripts cited was 0.97. The total number of authors who participated in the cited manuscripts was 351. The highest IIS-A score, which was calculated in consideration of each author's participation and the weight of the manuscript, was 203.26. The number of institutes that had produced the cited manuscripts was 35. The highest IIS-I score, which was calculated in consideration of each organization's participation and the weight of manuscripts, was 187.45. CONCLUSION: If the indicators developed by the authors are used as tools to analyze the citation indices of the journals, they can quantify the contribution of the manuscripts, authors and institutes to each journal, and promote the development of academic journals based on the quantified contribution.

Endoscopic Submucosal Dissection (ESD) is curative treatment for early gastrointestinal neoplasia, and this procedure does not involve open surgery. Significant advances of the techniques and instruments for ESD have been made and many medical institutes have the facilities to perform ESD. This article reviews the current status of ESD in Korea.

Leptogium (Ach.) Gray is distributed throughout South Korea; however, for nearly two decades no detailed taxonomic or revisionary research on this lichen genus has been conducted. This study examined the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and samples were identified using descriptions recently published in the scientific literature. In this revisionary study, a total of fourteen species of Leptogium were documented, including new records of Leptogium delavayi Hue, Leptogium denticulatum Nyl., and Leptogium trichophoroides P. M. Jorg. & A. K. Wallace. Detailed descriptions of each species are given, including their morphological, anatomical, and chemical characteristics. A key to all Leptogium species known to occur in South Korea is also presented.

Three species of Coccocarpia have been reported from Korean Peninsular. However, there was no revisional study on this genus before. After careful examination of the specimens deposited in the Korean Lichen Research Institute (KoLRI) and collected from main mountain areas of Korea, two species of Coccocarpia, C. palmicola and C. erythroxyli, have been revealed to occur and confirmed in South Korea. The presence and absence of isidia and apothecia are the most important characters for the South Korean species. We provide the detailed description and illustration of the available two species. A key to the species is also provided.

Lobaria (Schreb.) Hoffm is a common foliose lichen genus found on the Korean Peninsula, yet until now, no revision study has been done on this genus. After careful examination of specimens deposited in the Korean Lichen Research Institute (KoLRI), nine distinct species of Lobaria were confirmed. Morphological characteristics such as the presence or absence of isidia, or whether or not the surface was ridged or smooth, and chemical characteristics such as the result of the medulla reaction were of significant importance in the differentiation of species. Here, we provided detailed descriptions together with a key to all the known Korean species.
