  • Background: Ranavirus is an emerging infectious disease which has been linked to mass mortality events in various amphibian species. In this study, we document the first mass mortality event of an adult population of Dybowski's brown frogs (Rana dybowskii), in 2017, within a mountain valley in South Korea. Results: We confirmed the presence of ranavirus from all collected frogs (n = 22) via PCR and obtained the 500 bp major capsid protein (MCP) sequence from 13 individuals. The identified MCP sequence highly resembled Frog virus 3 (FV3) and was the same haplotype of a previously identified viral sequence collected from Huanren brown frog (R. huanrenensis) tadpoles in South Korea. Human habitat alteration, by recent erosion control works, may be partially responsible for this mass mortality event. Conclusion: We document the first mass mortality event in a wild Korean population of R. dybowskii. We also suggest, to determine if ranavirus infection is a threat to amphibians, government officials and researchers should develop continuous, country-wide, ranavirus monitoring programs of Korean amphibian populations.

  • Background : This is an investigative study to analyse the importance of works perceived by Quality Improvement(QI) Coordinators and to evaluate their current work performances using the questionnaires developed by the investigator. Methods : The data were collected from 37 subjects over two weeks period from Oct. 1 to Oct. 17, 1998 and analysed by the descriptive statistics of SPSS program. The items of questionnaire are consisted of 13 work domains including 73 activities based on Quality Management(QM) Coordinator's job description of National Association for Healthcare Quality:data collection & analysis, communication, monitoring, evaluation, accreditation, tool development, policy development, program development, self development, education & trainning, system design, planning, and consultation & support. Results : 1) Of the performances in 13 work domains, the frequencies of the work performed were accreditation(89%), planning(88%), communication(83%), data collection & analysis(82%), monitoring(76%), policy development(72%), consultation & support (71%), education & trainning(70%), self development(68%), evaluation(63%), tool development(61%), program development(44%) and system design(43%) in order. 2) For the importances (1=not important, 5=very important), the policy development(4.46) scored highest then monitoring(4.42), planning(4.41), education & trainning(4.38), communication(4.35), evaluation(4.34) tool development (4.30), data collection & analysis(4.29), program development(4.22), consultation & support(4.22), accreditation(4.15), self development(4.05) and system design(3.98) in order. 3) There was a difference between the work performance and the perceived importance. The results showed the low performances in policy development, monitoring, education & trainning and evaluation which ranked high by the perceived importance and the high performances in accreditation, data collection & analysis, self development, communication and consultation & support which ranked middle to low by the perceived importance. 4) The reasons for low performances of QI Coordinators were the lack of clear assignment for the responsibility and allowed authority for work to QI Coordinators(30.8%), insufficient member of QI Coordinators(13.9%), lack of hospital director's interest(11.5%), low motivation of QI Coordinators (10.6%) and insufficient knowledge & experience of QI Coordinators (8.8%). Conclusion : Most works were perceived important by QI Coordinators, but there was a difference in the work performance. The works performed over 70% were related with accreditation, data collection & analysis, communication, planning and monitoring, on the other hand under 50% in performances were related with system design, program development, tool development and evaluation.

  • In the 1640's and 1650's, Milton wrote many prose works on a variety of topics such as education, church polity, divorce, censorship, regicide, tithing, civil liberty, and blindness. Much of his prose shows us turbulent decades of English history. In this period, he also published his first collection of poems and wrote sonnets. He wrote 23 sonnets in his life, and many sonnets Milton wrote after he had become Latin secretary are occasional poems in historical time. Milton's sonnets, as Annabel Patterson says, are a marker in his personal development, in his life, in his career as a writer, and in the history of his time. Four sonnets (15, 16, 17, 23), written between 1648 and 1655, were not published in the collected edition of Milton's poem in 1673. These sonnets, addressed to leaders of the Parliamentary party during the English revolution, Thomas Fairfax, Oliver Cromwell, and Henry Vane, and to his friend Cyriack Skinner, have been known as "commonwealth" sonnets. They are also called as "heroic sonnets" because they have the common style and theme with his later heroic epic poems. These sonnets were finally published in 1694 by Milton's nephew John Phillips. Milton was interested in religious, domestic, and political liberty for his lifetime, and his heroic sonnets also deal with these ideas of liberty. Milton asks civil liberty from Fairfax, freedom in religion from Cromwell, and from Vane for the reconciliation of both. The aim of this article is to examine how the rhetorical strategies of his "left-handed" prose interact with those of his "right-handed" poetry. This paper explores the relationship between Milton's heroic sonnets and his prose works, such as The Second Defense of the People of England, A Treatise of Civil Power, and The Likeliest Means to Remove Hirelings. Milton deals with the critical issues of religious tolerance, the separation of church and state, liberty of conscience and defense of his blindness, and attempts to define the statesman's role in peacetime England in these heroic sonnets and prose works.

  • 문헌의 교감으로 원문의 정확을 기하는 일은 학문연구의 중요한 기초작업이다. 시조의 경우 장구한 구전시대를 거친 후 필사에 의한 문자 정착을 보게 되었는데 착오없는 원작전승에 배려없이 전사를 거듭한 결과 현전하는 가집의 작품들은 원작의 변리현상을 피할 길이 없었다. 따라서 시조작품의 원모를 찾는데는 여러 시조집의 작품을 대교 교감하여야 할 것이요 그 길은 졸저 교본 역대시조전서에 의거하여야 할 것이다. 이 책은 시조의 작품 뿐 아니라 작가, 곡목까지도 교감이 가능하다. 고산윤선도의 작품을 예로 하여 그이 작품이 어느 책에 어떻게 전파되고 있는가를 살펴보고 특히 어부사시사가 예로 고산 유고와 해동가요의 대비에서 원작의 변개상황을 교감으로 살펴보았다. 고산의 작품은 의외로 그 전파가 좁았다. 고산의 어부사시사가 원문의 첨삭 변개로 시조화되어 수종 시조집에 전하는 중에는 특히 해동가요에 두드러지게 나타난다. 어부사 40수중 38수가 해요에 전한다. 그러나 그 중 5수는 변개되고 있는데 그 중에는 원작으로 다루는 데에는 문제가 되지 않을 수 없는 작품도 있다. 해요의 편저자 윤선도 소개란에 「어부가 오십이수」라고 하여 어부사가 아닌 작품까지 합산하여 어부가로 다루며 해요에 수록하고 있어 의간을 남기고 있다. 이 한가지 예로서 시기연구에서 교감문제의 많은 과제가 있음을 밝혀 보았다. 이 방면의 연구가 미흡함을 느끼며 새로운 연구가 나오기를 기대하는 바이다.

  • 본 연구는 산지황폐계류에 시공한 사방공작물이 계곡생태계에 미치는 영향을 분석하고자 시공 전후를 기준으로 조사지점별로 저서성 대형무척추동물의 출현종의 변화분석 및 생물학적 수질평가를 실시하였으며, 그 결과는 다음과 같다. 시공 전 출현한 저서성 대형무척추동물의 총 수는 4문 6강 11목 22과 25종 3,086개체였으나 시공 후 조사에서는 4문 6강 10목 17과 19종 1,208개체로 감소하였다. 특히, 직접적인 사방공작물의 시공이 이루어진 조사지점에서는 시공 후 생물종이 전혀 출현하지 않거나, 극소량만이 채집되어 서식종의 현존량을 기초로 하는 다양도 지수, 풍부도 지수, 균등도 지수가 감소 또는 산출되지 않았다. 저서생물의 군집분석 결과 및 저서성 대형무척추동물의 생태점수(ESB)는 모든 조사지점에서 시공전보다 시공 후에 오수생물계열, 환경상태, 수질등급과 같은 계곡환경질이 저하된 것으로 나타났다. 즉, 시공전 상류는 양호 및 다소 양호, 중류는 다소 불량, 하류는 불량 및 매우 불량으로 분석되었으나, 시공 후 상류 일부 지역을 제외한 나머지 수역은 매우 불량으로 분석되었다. 또한 대상 계류의 수질등급의 경우 시공 전에는 $I{\sim}III$등급 사이로 분류되었으나, 시공 후 대조군을 제외하고는 모두 $IV{\sim}V$등급으로 악화되었다 이와 같이 사방공작물의 시공후 모든 조사지점에서 발생한 저서성 대형무척추동물의 서식 환경 파괴는 개체수의 감소와 수질악화로 이어졌다. 이 결과는 사방공작물의 시공 직후에 조사 분석한 것이므로, 향후 장기간의 모니터링을 통하여 시공한 사방공작물의 재해방지 효과와 함께 계류 생태계의 회복과정에 대한 지속적인 연구가 이루어져야 할 것이다.

  • This paper is concerned with the development of remote vibration measurement system using the internet. Recently, various techniques are developed based on the advance of the internet environment. In this study, we developed the remote vibration measurement system using the internet server programming technique, the client programming technique, the GPIB programming, and the A/D, D/A programming techniques. Hence, we can control the measurement devices remotely. The feasibility of the system is validated using the experimental setup. The output of the D/A is connected to the small exciter and the piezoceramic sensor is connected to the A/D port. By sending out the exciting signal to the structure, we can collect the response. The experiment shows that the proposed idea works well. Another experiment consists of the function generator and the low-pass filter circuit. The wave form, amplitude, and the frequency of the function generator is controlled by the GPIB program and the output of the circuit is collected by the A/D port. The output is then displayed in HTML format.

  • It is important to investigate into the critical success factors of the CIO system in order to formulate a successful introduction strategy of the system. In an effort to provide the background of the strategy, this research attempts to identify the characteristics of CIO's environment in Korea, such as the CEO, the colleagues, and the demographic statistics of the firm the CIO works for. A result from the analysis of data collected shows that about half the firms who responded to the survey have already adopted the CIO system. This implies that the value of the system is well recognized in Korea, considering that many of another half the firms are planning to adopt the system. Another result suggests that the bigger a firm is, the more the firm tends to adopt the CIO system and the higher the rank of CIO's colleagues is.

  • Most construction works on the soft ground adopt instrumentation to manage settlement and stability of the embankment. The rapid progress of the information technologies and the digital data acquisition on the soft ground instrumentation has led to the fast-growing amount of data. Although valuable information about the behaviour of the soft ground may be hiding behind the data, most of the data are used restrictedly only for the management of settlement and stability. One of the critical issues on soft ground instrumentation is the long-term settlement prediction. Some observational settlement analysis methods are used for this purpose. But the reliability of the analysis results is remained in vague. The knowledge could be discovered from a large volume of experiences on the observational settlement analysis. In this article, we present a database to store settlement records and data mining procedure. A large volume of knowledge about observational settlement prediction were collected from the database by applying the filtering algorithm and knowledge discovery algorithm. Statistical analysis revealed that the reliability of observational settlement analysis depends on stay duration and estimated degree of consolidation.

  • The Kosachalyo was the reference book which was composed of records collected about the procedures regulating the foreign relations or daily lives of the officials or the scholars, who had no official positions, in the Yi dynasty. The compilation work of the Kosachalyo was started from the date of the compilation of the original one by U sook-kwon (魚叔權) in the 9th year (1554) of King Myongjong (明宗). Su Myongung (徐明) revised and complemented the contents of the original one in full scale, named it as the Kosashinsu(攷事新書) in the 47th year(1771) of King Yongjo(英祖). In that period, the original Kosachalyo was revised and complemented twelve times and republished. Until now, it has been said that the original Kosachalyo had been suffered the revising or complementing works six times or nine times. But in this thesis it is assured that it was revised or complemented twelve times in the period from 1554 to 1771 upon the various historical documents.

  • Since the solar radiation is the main input for sizing any solar photovoltaic system, it will be necessary to understand and evaluate the solar radiation data. The works presented here are the analysis of solar radiation data for East Asia areas. The data, which consist of the global radiation on horizontal surface, were measured at 16 different stations over the South Korea and were estimated by using satellite at 12 different stations over the North Korea from 1982 to 2004. Also the data over the Japan have been collected for 30 years for the period from 1941 to 1970. The Result of the analysis shows that the annual-average daily global radiation on the horizontal surface is $3.55\;kWh/m^2$. We conclude, based on the analysis, that East Asia areas have sufficient solar energy resources for the photovoltaic power generation system.
