  • Extensive survey of invertebrates in Korea, led by the National Institute of Biological Resources in Incheon, continues to uncover many new and endemic species, but also elements of neighbouring faunas that were previously unknown here. Hemicyclops tanakai Itoh and Nishida, 2002 was originally described from estuarine mud-flats in Tokyo Bay, Japan. We report one male and two females from a sandy beach on Jeju Island, which represent its first record in Korea and second record ever. No morphological differences were observed between these two disjunct populations, so we expect more records of this species in Korea and Japan. Tisbe ensifer Fischer, 1860 was originally described from Madeira and later on reported from numerous other parts of the Northern Atlantic, as well as from the Indian Ocean. We report two females from a shallow littoral in Sokcho, which represents its first record in Korea and the first record in the entire Pacific Ocean. Because of morphological discrepancies reported in previous records we recognize that this species might be in reality a species complex, and we only tentatively identify our Korean specimens as T. cf. ensifer. We provide numerous light photographs of both species in addition to short descriptions, in hope that they might elucidate global problems of their zoogeography and dispersal of small marine invertebrates in general. Further samplings from Korea and other parts of the world will be necessary to test our identifications and phylogenetic relationships of Korean populations with molecular and other tools.

  • Considering the vast usage of time-history dynamic analyses to calculate structural responses and lack of sufficient and suitable earthquake records, generation of artificial accelerograms is very necessary. The main target of this paper is to present a novel method based on nonstationary Kanai-Tajimi model and wavelet transform to generate more artificial earthquake records, which are compatible with target spectrum. In this regard, the generalized nonstationary Kanai-Tajimi model to include the nonstationary evaluation of amplitude and dominant frequency of ground motion and properties of wavelet transform is used to generate ground acceleration time history. Application of the method for El Centro 1940 earthquake and two Iranian earthquakes (Tabas 1978 and Manjil 1990) is presented. It is shown that the model and identification algorithms are able to accurately capture the nonstationary features of these earthquake accelerograms. The statistical characteristics of the spectral response of the generated accelerograms are compared with those for the actual records to demonstrate the effectiveness of the method. Also, for comparison of the presented method with other methods, the response spectra of the synthetic accelerograms compared with the models of Fan and Ahmadi (1990) and Rofooei et al. (2001) and it is shown that the response spectra of the synthetic accelerograms with the method of this paper are close to those of actual earthquakes.

  • 야구는 매 경기마다 다양한 기록을 생성하며, 이러한 기록을 기반으로 다음 경기에 대한 승패예측이 이루어진다. 프로야구 승패 예측에 대한 연구는 많은 사람들에 의해 행해져 왔으나 아직 이렇다할 결과를 얻지 못하고 있는 상태이다. 이처럼 승패 예측이 어려운 이유는 많은 경기 기록들 중 승패 예측에 영향을 주는 요소의 선별이 어렵고, 예측에 사용된 자료들 간의 중복 요인으로 인해 학습 모델의 복잡도만 증가시킬 뿐 좋은 성능을 보이지 못하고 있다. 이에 본 논문에서는 전문가들의 의견을 바탕으로 학습 요소들을 선택하고, 선택된 자료들을 이용하여 휴리스틱 함수를 구성하였다. 요소들 간의 조합을 통해 예측에 영향을 줄 수 있는 새로운 값을 산출함과 동시에 학습 알고리즘에 사용될 입력 값의 차원을 줄일 수 있는 혼합형 모델을 제안하였다. 그 결과, 학습 알고리즘으로 사용된 역전파 알고리즘의 복잡도를 감소시키고, 프로야구 경기 승패 예측에 있어서도 정확성이 향상되었다.

  • The author analyses the challenging activities of Japanese libraries in this decade by launching two keywords; "product-sharing" and "outcome generation." "Product-sharing" means that libraries share knowledge, skills, and records which are produced as the result of the services or in the process of activities. And "outcome generation" means that libraries generate any efficiency or effectiveness through their services to users. Using these concepts, reported are the current situation and aspects of Japanese libraries which try to make various contributions to the society; research and learning of the people, and education and training for professional librarians, and so on. In the analysis, the author shows some examples of "product-sharing" at first, including the records of reference transaction and the multi-functioned online public access catalogue. Especially, focused is on the various possibility and adoptability of the Collaborative Reference Database System of the National Diet Library of Japan. This system is one of digital reference service in Japan, and the database of reference transaction records is expected to be useful for research and academic studyies as knowledge-base of professional librarians. And the system is also expected to be a platform for LIS education and professional development in the e-learning environment. Secondly, as the examples of "outcome generation", explained are the problem-solving-type activities, and provision of the collection about books on struggling against disease and illness. A few examples of outcome in the problem-solving-type activities are these; increase of sales in the services for shop managers, business persons, and entrepreneurs, contribution to affluent daily life by providing the local information services to residents and neighbourhoods, and etc. And for both the patients with serious cases and their family or those who nurse them, books about other persons' notes or memorandum are the greatest support, and sometime healing. The author discuss the 'raison d'etre' of these activities focusing on public libraries in Japan.

  • Objectives : The purpose of this study is to find the differences of the viewpoints about medicine between Korean and Japanese doctors through analysing the contents of the medical conversation records from the visits of Joseontongshinsa. Methods : The conversations were classified according to the topics and analysed with emphasis on the subject of medical classics. Results : Japanese doctors were skeptical about the application of Huangdineijing(黃帝內經) and the theory of Five Circulation and Six Qi(五運六氣) to clinical treatment while they respected Shanghanlun(傷寒論). They were interested in the bibliography of medical classics, and considered it was important to study the original texts rather than the new editions. The doctors of Joseon valued Huangdineijing highly and accepted the theory of Five Circulation and Six Qi. They mainly used the treatments in Yixuezhengzhuan(醫學正傳), Yixuerumen(醫學入門), Shoushibaoyuan(壽世保元) as therapeutic methods. Conclusions : The conversation records reflect the trend of Korean Medicine in the Joseon Dynasty that Huangdineijing had been mainly studied and the Jin-Yuan(金元) Medicine had been accepted, and the trend of Japanese Medicine in the mid-Edo period that Koho school(古方派) had predominated.

  • The 2015 version of the bibliographic checklist of Korean spiders from the first checklist by Paik and Kim (1956) is presented, together with a complete bibliography of relevant Korean araneological literature. A total of 620 publications during 1907-2015 including original description on the Korean spiders and records of taxonomic description were critically reviewed. Records only from locations within the present borders of South Korea are listed. A total of 748 spider species of 271 genera belonging to 46 families are confirmed to exist in Korea. Twenty one species, whose distribution or existence within the Korean border are uncertain and lacked valid records, are excluded from the present list pending critical validation. Four spider species endemic to North Korean are listed separately from the present list. One genus, Joopilia Chae and Sohn, 2013 and 2 species, Joopilia jooplis Chae and Sohn, 2013 and Dolomedes jirisanensis Kim and Chae, 2012, which had no designated type species and no diagnosis, are cited as nomina nuda. New synonyms of 15 previously described spider species are proposed. Based on their zoogeographical distribution, the Korean spider fauna was found to be influenced by the northern species, including 36 Holarctic and 72 Palearctic species (14.5% of the total species). Korean endemic species include 160 species (21.5% of the total species). Korean indigenous spiders are also distributed in neighboring countries: 318 species in Russia (42.7%), 460 in China (61.7%), and 488 in Japan (65.5%).

  • One of the problems facing in all modern dental hospitals is the much efforts, manpower and space are needed to effectively sort and stack patients' charts of the various dental departments. In addition, the storage and prompt arrangement of x-ray films is also a problem. Therefore, if dental charts as well as films could be computerized, it would be easier to store and keep them; by data basing, many space, manpower and cost would be saved: data could also be effectively managed for the purpose of academic researches. This would be an epoch -making event in the development of dental hospital management. The purpose of this study is to develop a dental information processing program, that will be used to store dental treatment records and digital image data using a new record media, the optical card. The patients' charts from the dental hospital were selected. The treatment records of the chart were put into the treatment data -recording area of the program, and the digital images of various dental x-ray films were made with a scanner. These data were stored in the optical card and analyzed to get the following results: 1. In this program it is possible to put treatment records and image data into and out from the optical card, and it is impossible to correct and delete all data recorded on the optical card. 2. All data in the optical card system can be searched and analyzed on database. 3. The resolution of image data stored in optical card is above 5.9 lp/mm. 4, All data of dental charts used as samples, stored to optical cards, occupies average 14%, In conclusion, with the development of the storage system using the optical card, a dental patient's life-time treatment record can be stored in one optical card and used as a substitute for the dental chart.

  • 커뮤니케이션 언어로서 텍스트보다 사진, 이미지, 영상 등 비(非)텍스트 기록의 중요성이 커지고 있다. 이에 따라 국내 기록관리 유관 기관과 전문가들 또한 이미지 기록의 특수성에 적합한 기록관리 체계 마련의 필요성에 공감하고 있다. 이 글은 2018 국제 영상기록 관리연수(INA Frame)에 참가한 경험을 토대로 국내 영상기록관리 체계 마련을 위해 고민해야 할 지점들을 정리한 글이다. 특히 국가적 차원에서 관리해야 할 대상을 단순한 영화, 방송, 문화콘텐츠 등을 포괄하는 다양한 유형의 콘텐츠에서 더 나아가 '공공영상문화유산'의 개념정립의 필요성에 대해 역설하였다. 또한, 관련 제도 인프라 정비, 기관 또는 거버넌스 설계 등과 같은 '기반구축'에 해당하는 여러 과제들을 검토하여 이 선결과제들이 향후 국내에서 안정적인 '공공영상문화유산' 관리체계 마련으로 이어져야 함을 강조한다.
