In For the past few years, query log data has been collected to find user's behavior in using the site. Many researches have studied on the usage of query logs to extract user's preference, recommend personalization, improve caching and pre-fetching of Web objects, build better adaptive user interfaces, and also to improve Web search for a search engine application. A query log contain data such as the client's IP address, time and date of request, the resources or page requested, status of request HTTP method used and the type of browser and operating system. A query log can offer valuable insight into web site usage. A proper compilation and interpretation of query log can provide a baseline of statistics that indicate the usage levels of website and can be used as tool to assist decision making in management activities. In this paper we want to discuss on the tasks performed of query logs in pre-processing of web usage mining. We will use query logs from an online newspaper company. The query logs will undergo pre-processing stage, in which the clickstream data is cleaned and partitioned into a set of user interactions which will represent the activities of each user during their visits to the site. The query logs will undergo essential task in pre-processing which are data cleaning and user identification.

The elementary idea of 'function-words' in Classical Chinese originates from Han dynasty. But because of the pictographic nature the methodology for 'content words' had been applied to the study on 'function words', ane the conditions had not changed until modern times. In grammar functions of the function-word syntactical, morphological in unit sentence were studied in this using the method of quantitative analysis for all the function-words appeared in ${\ll}$Hwang je nae gyung-Somun${\gg}$. In the previous studies about function word, many data were collected and analyzed diachronically. But those studies failed to examine function-words closed in connection with synchronic study. Besides, in the explain about relevant function-words also, the case which was made centering around exegetic explain was most. And in the case to explain the function-words have in unit sentence also, the explain only about some function-words is made, but the analysis about concrete function to have in syntactical system is being handled negligently. This study stands not only on the background df the traditional studies but also on the basis of the western grammar and linguistics, especially the descriptive grammar and linguistics, especially the descriptive grammar. ${\ll}$Hwang je nae gyung-Somun${\gg}$ is collect and recorded the mythology and special contents related to Daoism in the side of contents as what was written on the basis of the historical consciousness of individual in contents regardless of compilation system. The purpose of this study is to clarify how the role and function of fuction-words are being made in the composition of unit sentence which appeard in ${\ll}$Hwang je nae gyung-Somun${\gg}$ through synchronic grammar system.

"Yumunsachin(儒門事親)" is a very important work that contains everything of Jangjahwa(張子和)'s medical thought. The book was made into present form after the process of change several times. These days the printed book is consist of 10 classes and 15 volumes that combine several books. Original "Yumunsachin(儒門事親)" was the name of volume 1, 2, 3, "Chibyeongbaekbang(治病百法)" volume4, 5, "Siphyeongsamnyo(十形三標)" volume 6, 7, 8, "Japgigumun(雜記九門)" volume 9, "Chwalyodo(撮要圖)" volume 10, "Chibyeongbaekbang(治病雜論)" volume 11, "Sambeop-yukmun(三法六門)" volume 12, "Samsoron(三消論)" volume 13, "Chibeoppillyo(治法心要)" volume 14, and "Sinhyomyeongbang(神效名方)" volume 15. "Yumunsachin(儒門事親)" is a collection of a few books so, the literary style isn't uniform. The unconformity show that "Yumunsachin(儒門事親)" was not written by one person. The problem who is the writer of each volume remains controversial. But most scholars recognize that volume 1, 2, 3, original "Yumunsachin(儒門事親)" and was written by Jangjahwa(張子和), embellished by Majigi(麻知幾). Also, it is recognized that "Samsoron(三消論)" was collected by Majigi(麻知幾) and inserted by posterity, and that Sangjungmyeong(常仲明) and Nangi(欒企) who were Jang[張子和]'s disciples participated in compilation of "Yumunsachin(儒門事親)". Therefore, it is sure that the contents of the book express Jangjahwa(張子和)'s medical thought.

최근 들어 ARM 구조에서 가상화를 구현하기 위해 다양한 연구들이 진행되었다. 현재의 ARM 구조는 전통적인 에뮬레이션 방법인 "trap-and-emulation"으로 가상화 할 수 없기 때문에, 게스트 커널 수행 시간에 가상화 민감 명령어를 탐지하여, 이를 직접 수행하는 대신 가상화 에뮬레이션 한다. 일반적으로 가상화 에뮬레이션은 이진 변환 또는 인터프리테이션 방법으로 구현한다. 본 연구는 인터프리테이션 방법을 기반으로 하는 가상화 에뮬레이션의 성능 향상에 관한 것이다. 인터프리테이션은 명령어 페치, 명령어 디코딩, 그리고 명령어 수행의 단계로 이루어진다. 본 논문에서는 게스트 커널의 컴파일 시간에 모든 가상화 민감 명령어를 디코딩하여, 게스트 커널의 수행 시간에 인터프리테이션 시간을 줄이는 방법을 제안한다. 본 연구의 방법은 인터프리테이션 기반의 가상화 방법에서 에뮬레이션 코드를 간단하게 하고, 에뮬레이션 성능을 향상시킨다.

The characteristics of the records management systems of the Japanese colonial government can be summarized as follows. First, the Government General adopted a "decentralized retention" of public records. The Government General did not establish its own archives for central preservation of permanent public records. Colonial agencies established its own records office and the records office managed the records its agency created. Secret records and police records were exception. They were retained by the Secretary Office of the General Affairs Division and Police Division of the Chosun Government General respectively. Second, filing systems and retention periods of the public records followed the hierarchic structure of organization. In the headquarter of the government, records were filed by a "bureau-division-activity-file" classification system and a retention period of a file was given automatically by each unit the file belonged. A closed and cut-off file was retained and arranged according to its creating unit, creating year, and retention period. The filing system was easy to use once the filing system was established well, but to make it work effectively changes in activities and organizations should be on a reflected regular basis. It had an advantageous effect that permanent records could be preserved in a unified way throughout the organization. However, it is very critical to determine the permanent records in a professional way. Selection of the permanent records should be done professionally and in a historical perspective. Otherwise, the records retained as permanent records were not the records having an enduring value. And that was not done by the colonial government. Third, classification and scheduling of records were carried out by a creating division, rather than by the Records Office, mostly from the 1920s. Compilation of the records was also done by the creating agency. It implies that the records management lacked the professionalism. In conclusion, the records management system of the Chosun Government General wes nither modern nor user oriented. It managed the records for solely administrative purpose, i.e. effective colonial rule. The legacy of the colonial records system still exists in the public records system in Korean government. One should criticize the lack of will and efforts to modernize the public records system since the establishment of the Korean government while should reflect the historical origins of the records system in Korea.

The $S{\bar{u}}tra$ of Great Dhāraṇī of the Uṣṇīṣa-cittā is one of the most widely published scriptures of Esoteric Buddhism during the Goryeo and Joseon dynasty. The sutra is often referred to as a Buddhist medical scripture whose recitation is believed to allay diseases such as difficult birth, chest pain, and infectious and incurable diseases. It utilizes two major methods for healing: reciting and copying the sutra or copying the dharani and talisman which appear at the end of the text with fine cinnabar and ingesting them with aromatic water. In order to understand the medical and historical value of this sutra, this study examines the historical background of its establishment in early China and its migration to Korea in the Goryeo period. This study also investigates the identity and value of the scripture in Buddhist medical history. The oldest known printed texts of the sutra in Korea are dated to the late 11th century. Because of the material benefits of the text, the tradition of printing and distributing the sutra was very popular between the 13th and 19th centuries. Therefore, examples of the sutra having been used for medicinal purposes during rites are found in historical records. Finally, the study tries to identify the relationship between the treatment methods of the Sutra and those of Korean traditional medicine focusing on several Korean traditional medical texts such as the Hyangyak-Jibseongbang (Compilation of Native Korean Prescriptions), the Donguibogam, and the Euibang-Hapbu.

Present work aims to establish the countermeasure for the better maintenance and preservation of insular floristic diversity at the South Sea of Jeollanamdo Province, ROK, where unique ecosystems are under threat due to climate change, anthropogenic disturbance and habitat destruction. Numerous flora reports from 15 inhabited islands and 60 uninhabited islands as well as field survey data are collated for the compilation of floristic data base and island biogeographical analysis. Out of the 1,940 vascular plant species from 180 families occurring in studies areas, 30.1 percentage or 584 plant species are physiognomically belonging to arboreal plants. Average number of species at individual island is numbered about 222 species, but it varies from about 591 species at the inhabited islands to 129 species at the uninhabited islands. Only 0.15 percentage of species with high proportion above 0.9 in its relative occurrence rate occurs at 68 islands and it includes three species, such as Pinus thunbergii, Eurya japonica and Pteridium aquilinum var. latiusculum. However, about 68 percentage of plant species occurring in study area is confined their distribution to less than seven islands. Presence of high proportion of notable plants in small islands, i.e., 10 critically endangered species compared with 5.5 species in average, 9 endangered species (average 4.2 spp.) at Sonjookdo, and 7 critically endangered species, 8 endangered species at Sokomundo may due to existence of diverse geological and topographical environmental diversity as well as lower human population density and remoteness from the mainland. Since island is small in size and geographically isolated, minor environmental and ecological burdens can cause the critical damages to the diversity of flora and vegetation, urgent island biogeographical research is needed for the scientific conservation and management of island biodiversity.
