Despite its importance as concrete proof of the distinctive charcteristics of 治腫術 and acupuncuture of Korea, 치종지남 was not only seldom mentioned, it was impossible to obtain. Fortunately, through KIOM's translation projects, its entity was revealed. A 경도대 collection version including traces of 丹波元簡's 識語, and a Chinese hand-copied version, whose existence was unknown before, could also be adapted to research. Through this research, the details of the impartation and preservation process of 治腫指南 and the fact that both the Univ. Waseda collection version and the Chinese hand-copied version both originate from the Chosun original could be understood.

XML 기반의 Single Window은 국제 표준에 입각하여 해운 분야의 전자문서를 사용하여 국제해사기구와 전세계적으로 공통된 양식을 사용한다. 이는 동일한 양식의 전자문서를 사용하는 사용자들 간은 통용될 수 있다는 의미이며, 민원인 입장에서는 정보의 재사용성과 중복 입력의 불합리함을 줄일 수 있다. 이로써 민원인들은 입출항 수속 간소화 뿐만 아니라 해운 업무 자체에 많은 업무 개선 효과를 볼 수 있다. 본 고에서 제안한 XML 인프라스트럭처(XML infrastructure for Single Window)는 ebXML 기반의 Single Window에 적합하도록 설계 및 구현되었으며, 자원의 재사용성과 중복 투자를 방지할 수 있도록 하였다. 즉, 사용 환경에 유동적으로 적용가능 하도록 컴포넌트 방식으로 구성되었으며, 기존 시스템을 최대한 활용하도록 구성할 수 있도록 하였다.

The pathogenesis and mechanism of obstructive sleep apnea (OSA) has been under investigation for over 25 years, but its etiology and mechanism remains elusive. Skeletal (maxillary and/or mandibular hypoplasia or retrodisplacement, inferior displacement of hyoid) and soft tissue (increased volume of soft tissue, adenotonsillar hypertrophy, macroglossia, thickened lateral pharyngeal walls) factors, pharyngeal compliance (increased), pharyngeal muscle factors (impaired strength and endurance of pharyngeal dilators and fixators), sensory factors (impaired mechanoreceptor sensitivity, impaired pharyngeal dilator reflexes), respiratory control system factors (unstable respiratory control) and so on facilitate collapse upper airway. Therefore, OSA may be a heterogeneous disorder, rather than a single disease entity and various pathogenic factors contribute to the OSA varies person to person. As a result, patients may respond to different therapeutic approaches based on the predominant abnormality leading to the sleep-disordered breathing.

Cloud computing is an evolving computing paradigm that has influenced every other entity in the globalized industry, whether it is in the public sector or the private sector. Considering the growing importance of cloud, finding new ways to improve cloud services is an area of concern and research focus. The limitation of the available Virtual Machine Load balancing policies for cloud is that they do not save the state of the previous allocation of a virtual machine to a request from a Userbase and the algorithm requires execution each time a new request for Virtual Machine allocation is received from the Userbase. This problem can be resolved by developing an efficient virtual machine load balancing algorithm for the cloud and by doing a comparative analysis of the proposed algorithm with the existing algorithms.

본 논문에서는 한국어 질의응답시스템에서 개체인식에 기반하여 대답을 추출하는 방법을 제안한다. 질의에 대한 문서검색을 통해 검색된 상위 문서를 대상으로 하여 대답이 들어 있을 가능성이 높은 단락을 추출한다. 질의 유형 분석을 통해 대답 유형을 파악한다. 단락에 나타나는 어휘들에 대해서 대답유형에 속하는지에 대한 개체인식을 통해서 대답을 추출한다. 질의응답 시스템의 평가를 위한 테스트컬렉션을 이용한 성능평가에서는 순위 5위까지의 대답추출에서 역순위 평균값이 개체추출에 대해서는 0.322, 50바이트 대답추출에서는 0.449, 250바이트 대답추출에서는 0.559이다. 상위 5이내에 정답을 포함할 비율은 개체추출에서는 48.90%, 50바이트 대답추출에서는 62.20%, 250바이트 대답추출에서는 68.90%을 성능을 보였다.

Ipsilateral fractures of proximal femur with shaft and condylar region are very rare. Current concept of management is based on fixation of each fracture as independent entity using separate fixation modalities for proximal and distal parts of femur. However, we considered that antegrade femoral nailing with cephalomedullary screw fixation is a good option for ipsilateral multi-level femoral fractures. Here, we present an experience of satisfactory treatment for ipsilateral femoral neck fracture, subtrochanteric fracture, comminuted shaft fracture with supracondylar fracture following road traffic accident.

Traditional web-based services that require users to browse via documents and fill out forms, are difficult to use with mobile devices. Moreover, as the web paradigm assumes active clients, further complications are introduced in cases where the server is the active entity, instead of the client. This paper presents a Server-Centric Interaction Architecture (SCIA) for wireless applications. The architecture enables servers to initiate communication with clients as well as push secure targeted data to them, in a piecemeal fashion. It further enables the development of highly collaborative wireless services with interactive user interfaces.

In animating an articulated entity with motion capture data, especially when the reconstruction is based on forward kinematics, there could be large discrepancies at the end effector. The small errors in joint angles tend to be amplified as the forward kinematics positioning progresses toward the end effector. In this paper, we present an algorithm that enhances the motion capture data to reduce positional errors at the end effector. The process is optimized so that the characteristics of the original joint angle data is preserved in the resulting motion. The frames at which the end-effector position needs to be accurate are designated as“keyframes”(e.g. starting and ending frames). In the algorithm, corrections by inverse kinematics are performed at sparse keyframes and they are interpolated with a cubic spline which produces a curve best approximating the measured joint angles. The experiment proves that our algorithm is a valuable tool to improve measured motion especially when end-effector trajectory contains a special goal.

This paper examines that a desirable organizational structure for a security policy in ubiquitous environments that are based on users' need to know and do their tasks in organizations. Tasks are a common entity which already exit and relate directly to both users(who are assigned to tasks and to information required for the completion of a task). Ubiquitous is highlighted as IT paradigm of the future generation. We propose a security model, called the Ubiquitous Group Security Model(UGSM), which associates with a task of processing the information which users need to know. The access type specification restricts the operations that users are permitted to perform, as defined by users' need to do for achieving their tasks in organizations.

B2B 전자상거래와 같이 XML을 이용한 정보교환이 확산되고 있으며 이에 따라 상호 교환되는 정보에 대하여 체계적이며 안정적인 정장관리가 요구되고 있다. 이를 위해 XML 응용과 데이터베이스 연계를 위한 다양한 연구가 관계형 데이터베이스를 중심으로 수행되었다. 본 논문에서는 EER 스키마로부터 XML 문서로 자동생성 되는 것을 단순화하기 위하여 알고리즘을 기술하고 관계형 데이터베이스 스키마로 변환을 시도했다. 특히 개념적 데이터 모델에 의해서 기술된 데이터 구조를 DTD로(Document Type Definition) 변환하는 방법을 나타낸다. 이 변환의 중요한 목적은 개념 스키마로부터 구조적인 정보를 가능한 한 많이 보존하는 것이다. 이것은 XML 파서가 가능한 한 일부분의 상태를 확인하고 서로 다른 데이터베이스사이의 데이터교환을 단순화한다. 특히 데이터베이스 스키마에서 XML 문서로 데이터를 가져오는 것이다. 개념 스키마의 알고리즘을 기준으로 하는 것은 매우 일반적이고 개념적 데이터 베이스의 데이터뿐만 아니라 객체-관계 데이터베이스의 데이터에 대해서도 알고리즘이 모델링될 것이다.
