현재의 컴퓨터 설문 시스템은 설문의 규칙이나 처리절차들을 하드코딩하는 방식으로 구현하기 때문에 설문이 변경되면 처리엔진을 수정해야 한다. 이것은 설문 처리엔진이 설문에 종속되어 있음을 의미한다. 본 논문에서는 이러한 약점을 해결하고자 능동문서 모델을 이용하여 설문으로부터 처리엔진을 독립시키는 방법을 고안하였다. 능동문서 기반의 설문지는 컨텐츠, 로직, 지식베이스(사용자 응답), 질의로 구성된다. 이 중에서 로직은 다양한 질문유형에 대한 처리 방법을 기술하는 것으로서 어떤 설문 설계자도 정의할 수 있어야 한다. 또한 로직은 직관적으로 서술할 수 있고 실행가능 하도록 XML 형식의 규칙 마크업 언어인 ERML로 표현하였다. ERML로 작성된 로직은 Prolog로 변환된 후 추론기에 등록되며, 사용자 응답에 따라 설문을 제어하고 처리한다. 마지막으로 몇 가지 질문유형을 ERML로 구현하고 설문 시스템(WINAD: The Web Interview System with Active Documents)에 적용한 실험 결과 설문으로부터 처리엔진을 독립시킬 수 있음을 확인했다.

최근 고객의 만족도나 선호도와 같은 정보를 수집하기 위해서 컴퓨터를 이용한 설문조사가 다양한 형태로 이루어지고 있다. 현재의 설문시스템은 지필형 설문에 비해서 여러 가지 이점이 있지만 여전히 부족한 점이 있다. 예를 들어 로직, 변수, 구성요소 등과 같은 처리절차 또는 규칙들이 시스템에 하드코딩되기 때문에 설문이 바뀌면 처리 엔진을 재설계하고 재구현해야 하는 점이 그것이다. 본 논문에서는 설문에 독립적인 시스템을 구축하고자 설문엔진과 로직엔진을 분리 설계하였으며, 각 설문에 설문처리 로직을 포함시킴으로써 기존 방식의 약점을 보완하고자 하였다. 설문에 로직을 포함시키고 구조화하기 위해서 능동문서(Active Documents)를 이용하였다.

현재의 컴퓨터 설문 시스템은 지필형 설문에 비해 여러 가지 이점이 있지만 처리절차 또는 규칙들이 시스템에 하드 코딩(Hard Coding)되기 때문에 설문이 변경되면 설문처리 엔진을 수정 또는 재구현해야 한다. 이러한 문제를 해결하고자 기존에 능동문서를 도입한 컴퓨터 설문 시스템인 능동문서 기반의 웹 설문 시스템(WINAD: The Web Interview System with Active Documents)을 구현하였다. 하지만 WINAD 시스템은 응답자의 참여도를 높이거나 응답률을 최대화할 수 있는 플래쉬, 플랙스, 실버라이트 등 인터렉티브한 설문지 작성 환경을 제공하지 않는다. 브라우저 상호호환성과 웹접근성 문제를 발생시키기 때문이다. 본 논문에서는 WINAD 시스템을 모바일 및 다양한 브라우저 환경에서 동작가능 하도록 HTML5 기술을 적용한 웹표준 기반 능동형 설문 시스템을 설계하였다.

본 논문에서는 센서 네트워크를 이용해서 환자 모니터링 시스템(PVMS : Patient Vital Sign Monitoring System)을 구현하였다. 최근 의료 서비스에 유비쿼터스 컴퓨팅 기술을 적용한 사례들이 늘고 있다. 기존 사례에서는 센서 전지 수명, 이동 통신비, 응급상황 대처 등 개선할 부분이 존재한다. 본 연구에서는 이런 점들을 해결하기 위해 환자의 체온 및 맥박 생체신호를 측정하기 위해 소형센서를 사용하였다. 또한 생체신호 전달을 위해 초저전력 무선통신 노드를 사용하여 언제 어디서나 환자 모니터링이 가능하고 의료진에게 응급상황을 신속하게 전달할 수 있는 웹기반 시스템을 개발하였다. 본 연구의 결과는 병동환자뿐만 아니라 활력증후를 상시로 모니터해야하는 원거리 환자를 위한 의료시스템 구축에도 활용될 수 있을 것이다.

In this study, the UAV (Unmammed Aerial Vehicle) was applied for the photogrammetry of the construction site and the safety management of steel pipe scaffold. The research site is a temporary facility for building reinforcement on Samcheok Campus of Kangwon National University. The installation condition of the steel pipe scaffold was investigated, and the pillar distance, the beam distance and the wale distance were surveyed. As a result, it was found that the beam distance of the scaffold in the longitudinal direction was in good agreement with the standard, but the pillar distance and the wale distance were found to be less than the standard. Three-dimensional data can be used in drone shooting to enable three-dimensional measurement, so that it is possible to measure facilities hidden or located inside other facilities. Through the drone shooting, the condition of the site can be quickly recorded and the surveying can be carried out without interfering with the work of the field personnel. Although the installation of the temporary structure must be strictly observed to ensure the safety of the workers, it is found that the installation standards are still neglected in the field. In order to prevent this practice, it was thought that the legal system should be supplemented so that it could be checked periodically by using UAV in the field process management.

The present study has been undertaken to investigate the effect of the extract of Cirsium japonicum var. ussuriense leaves (CLE) on blood circulation in a rat model of topical ferric chloride ($FeCl_3$)-induced carotid artery damage. $FeCl_3$ treatment seriously damaged the carotid artery such as the walls of the artery, blood flow and inflammation. However, CLE administration has ameliorated blood circulation and suppressed vessel inflammation. CLE administration also has ameliorated the $FeCl_3$-induced artery tissue damage. Furthermore, CLE significantly suppressed the expression of adhesion molecules. These results suggest that CLE ameliorate blood circulation through suppress inflammatory mediator and adhesion molecule production.

In this work, we compared the emulsion states having the same composition of liquid paraffin/ Span 80-Tween 80/ pure water and the different mixing paths and temperatures. Routes reaching the final composition in three component phase diagram were composed of three different ways. The average particle size of the emulsion prepared from the different mixing routes showed a significant difference and decreased as the mixing temperature was increased. However, the mixing route affected more in the size of the emulsions than mixing temperature.

Thuja orientalis extract (TOS) has been used on the hemostatic roborant, sedatives and stressless in oriental countries. We investigate the inhibitory effects on the productions of pro-inflammatory cytokines such as interleukin-1beta (IL-1β), IL-6, tumour necrosis factor alpha (TNF-α), and nitric oxide (NO) and the hair promotiont of TOS in the macrophage celline RAW264.7 or hair loss-induced DBA1J mice. T08 (50-500 ㎍/㎖) per se had no cytotoxic effect non-stimulated cells, but this extracts concentration-dependently reduced the release of NO, (IL-1β), IL-6, and TNF-α in the stimulate RAW264.7 cells with lipopolysaccharide (LPS). Moreover, when applied TOS (500 ㎍/㎖) to DBA 1J/mice, hair growth was promoted remarkably. These data suggest that T08 promotes hair growth on hair loss induced model mice and these properties may contribute to the anti- hair loss activity of the Thuja orientalis.

The classical ABC (avidin-biotin peroxidase complex) method for immunohistochemistry in the paraffin-embedded tissues bring into being disadvantage such as low sensitivity of antigen detection and highly background. The biotinyl-tyramide conjugation recently introduced for sensitive immunohistochemistry was applied to light microscopy in paraffin-embedded pancreatic and liver tissues. The protocol consists of an indirect method in which 4-5㎛ tissue sections are reacted successively within a specific primary antibody, followed by a biotinylated secondary antibody, streptavidin-horseradich peroxidase (HRP), and then finally with biotinyl-tyramide. The labeling obtained for insulin and collagen antigen tested in pancreatic and liver tissues, respectively, was found to be highly specific with the labeling for each antigen confined to its particular cellular compartment. In this study, fish (flounder) serum was specially applied to remove nonspecific binding. Background levels and nospecific deposition of the staining were negligible. This results suggest that super-signal induction method by biotinyl-tyramide conjugate can readily applied to antigen detection of the paraffin-embedded tissues.

The leaf of mulberry (Morus alba L) has long been used in Oriental medicine for the prevention or treatment of several diseases. However, little is known about the inhibitory effects of a single compound isolated from the mulberry leaves on inflammatory response. We are isolate a single compound of quercetin (3,3',4',5,7-pentahydroxyflavone) and astragalin (kaempferol-3-O-glucopyranoside) from the mulberry leaves, and then investigate the anti-inflammatory effects of quercetin, astragalin or quercetin plus astragalin in lipopolysaccharide (LPS)-stimulated murine peritoneal macrophages. Each compound suppressed the production of inflammatory mediators (NO, $PGE_2$ and IL-6) in LPS-stimulated murine peritoneal macrophages in a dose-dependent manner. Especially, the cotreatment of quercetin (2.5 ${\mu}M$) and astragalin (2.5 ${\mu}M$) markedly suppressed the production and the expression of inflammatory mediators. These suppressive effects were synergistically increased by their combination. These results suggest that the combination of quercetin and astragalin from the mulberry leaves may be useful for therapeutic drugs against inflammatory immune diseases, probably by suppressing the production of inflammatory mediators.
