선진 제국의 많은 출판사들은 기존의 출판방식과, 그들이 이제까지 의지해온 저작권법이 전자출판의 본격화로 일시에 와해될지도 모른다는 불안을 갖고 있다. 예컨대, 그들은 전자도서관의 방대한 네트워크 속에서 자료들이 이동되고 주물러지고 재구성될 경우, 이에 대한 저작권은 과연 누구에게 있는가를 심각하게 반문한다.

도시 지역의 대부분을 차지하는 건물에 대한 3차원 정보는 도로, 교통 등의 시설물관리시스템 구축, 도로계획, 택지개발, 도시계획 등 여러 분야에 필요하다. 현재 항공사진, 고해상도 위성영상, LiDAR 자료, 수치사진측량 시스템 등의 보급과 분석 알고리즘의 발전으로 인하여 도시지역 건물 3차원 모델링에 대한 연구가 활발히 진행되고 있는데, 그 중에서 정밀한 DSM 취득이 가능한 LiDAR 자료가 도시지역 건물 3차원 모델링에 가장 유망한 자료이다. 그러나 LiDAR 자료만을 이용할 경우에는 선형화 과정 등의 수작업이 많이 들어가고, 주관적인 재구성과정이 들어가야 하는 문제점이 있다. 따라서 본 연구에서는 수치지도를 LiDAR 자료와 같이 이용하여 건물 3차원 모델링시 작업자의 수동적인 과정을 단축하였다. 항공사진과 해석도화기를 이용한 정확도 평가 결과 1:5,000 수치지도 정확도 규정을 만족하는 도시지역 건물 3차원 모델링이 가능하였고, 비교적 자동화된 공정을 이루었다.

This study was a qualitative study using Colaizzi's phenomenological study method to understand the experience of reconstructing life through hemodialysis in chronic renal failure patients and to clarify the meaning of their vivid experience. The participants were eight chronic renal failure patients receiving hemodialysis. Data were collected through individual in - depth interviews with participants. The five categories that were found in the study were 'The beginning of unexpected difficulties', 'Burden of survival brought on by hemodialysis', 'The driving force of recovery', 'Choices and concentration of today in order', ' Every day life which must be woven sincerely'. The results of this study will help clinicians better understand the physical and mental suffering experienced by patients with chronic renal failure receiving hemodialysis and how they are constantly trying to adapt to a changed lifestyle. Also it might provide basic data for the development of efficient nursing intervention for the health management of hemodialysis patients.

This paper surveyed records and archives which the railroad stations in Busan possesses and illustrated the status of them. Also we examined whether records and archives of railroad stations contain the memories of localities or not. We visited 17 railroad stations in Busan and we found that 1) the archives in railroad station are fugitive archives 2) the records or archives are classified into five categories, 'station's history', 'report on station-adjacent area', 'report of drive and transport', 'photos', and 'other materials' 3) the volume of such archives in 17 stations are different because of disposal or missing 4) Each archives in same category have same form. Especially the descriptions and images in 'station's history', 'report on station-adjacent area' represent much to memories of locality, but we also must examine the public records, private records related railroad station in Busan for documenting localities. To bridge the gap we suggest to collect oral records by relevant persons.

This study is a life history study of the elderly of overseas chinese. The aim of study is to explain the acculturation of identity and attitude to korean and the experience of discrimination through of the work of reconstruction of life history. We approached narrative - life history analyze. The life history data were collected by in - depth interview. The authors analysed the text according to Rosenthal(2008). In first stage we recomposed narrative life history and finally we composed experienced life history. The result as follows. The hero of this study have lived wearing korean mask for survival in the land of emergency landing but he lived severely dreaming come home in glory. The life of hero of this study represented forfeit of identity. He couldn't root in korea, Taiwan and China.

n this paper, we implement the real-time scheduler which performs extended schedulability testing, to reconfigure Mach kernel in which Real-Time scheduling is possible. for this purpose, first, we propose the configuration factors according to requirements of Real-Time operation systems and we analyze a Real-time scheduling algorithm. Second, for the reconfiguration of Mach kernel, we propose the modified data structure through the analysis of Mach kernel environments and scheduling. Third, we suggest the extended scheduling method by analyzing conventional Real-Time scheduling policies. Fourth, we implement the scheduler which executes tasks according to the Earliest-Deadline-First scheduling and the Rate Monotonic scheduling.

SELinux is known as a secure operating system that is easily accessible to users due to the popularization of Linux, and is applied to various security operating system references deployed on systems such as embedded systems and servers. However, if SELinux is applied without considering the performance overhead of activating the SELinux kernel module, the performance of the entire system may be degraded. In this paper, we describe the factors directly affecting the performance inside the SELinux kernel and show that it is possible to improve performance by simply reorganizing the policy without changing the SELinux kernel. This can be used as a reference when security administrators or developers apply SELinux.

This study is to explain the interaction of muslem immigrant workers in korea. The author approached new ethnography study method. Ten of Muslem immigrant worker and 10 korea participated this research. Data were collected by in-depth interview and non-participation observation The author analyzed the date according to Spradey(1979)'s Developmental Research Sequence model. As result "From secular way to religious way", "Reconstruction of ultra ethnic religious" were presented cultural theme.

본 연구의 목적은 실험실에서 퇴적물의 다분광반사 특성과 물성을 측정하고 이를 위성 영상에 적용하여 영상에서 나타나는 퇴적물의 분광차이의 원인을 해석하고, 위성영상에서의 퇴적물의 분류 가능성을 연구하는데 있다. 연구에서는 Landsat TM위성 영상과 350~2500nm 파장대역에 대한 퇴적물 시료의 분광측정 자료를 사용하였으며, 기존의 조사 자료를 토대로 TM 영상에서 퇴적물을 분류한 후, 현장에서 시료를 채취하여 입도 분류를 실시하였다. 퇴적물의 입도와 함수비에 따른 분광특성변화를 검증하였으며, 입도와 함수비에 대한 회귀식을 구하여 이를 영상에 적용 분류하였다. 분석 결과 다분광자료 측정시 퇴적물입도에 따른 분광차이는 미약하였으며 이를 TM 자료로 재구성하였을 때는 분광특성을 구분할 수 없었다. 퇴적물의 분류는 TM Band 4, 5, 7을 이용한 회귀식을 적용할 때 비교적 정확하게 나타났으나, 영상에서 퇴적물의 분광 차이는 입도 크기가 직접적인 요인이 아니라 입도에 의한 함수비 및 유기물 함량의 차이에 기인한 것으로 해석된다.

A new era has come where high quality educational materials can be acquired easily through the World Wide Web. These materials, however, need to be refined and streamlined to maximize their effect on education. In order to provide such a streamlined flow, we need to be able to re-organize documents, which exist independent of each other on the Web, in a way that maintains their appropriate order in the right context to satisfy educational purposes. In addition, we should be able to provide supplementary explanations or missing information to the organized materials for smooth connections among them. In order to meet the requirements, we employed the virtual document concept that allows us to reuse existing documents for educational purposes. By providing a retrieval engine for virtual documents, we attempt to induce self-directed learning based on document retrieval, suitable for the level and purpose of students.
