The experiments were conducted to determine the factors such as light and darkness, phytohormone and seed coat, influencing on seed germination of Bidens tripartita L. and B. frondosa. The seeds of both species were germinated when seed coat was damaged and weakened GA3 and BA stimulated germination of both species but ABA and IAA had no effect on germination of them, which ranged 50.0% to 80.0%. In B. forndosa, when inner layer of seed coat was removed, germination was highly promoted up to 96.7% compared with 10.0% germination rate in another treatments.

도시 상업 공간은 성별에 따라 차별화된 특성을 가지며, 다양한 활용이 이루어진다. 그런데, 성별에 따른 도시 상업 공간의 특성 이해의 중요성에도 불구하고, 미시적 스케일에서 실증적 분석 연구가 제대로 이루어지지 못한 실정이다. 이러한 맥락에서 본 연구는 성별에 따른 도시 상업 공간의 탐색을 실증적으로 수행하고자 하였다. 이를 위해 서울시 신촌 지역과 이화여대 상업 지구를 대상으로, 건물의 투수성, 업종 분포와 공간 조직, 토지이용의 활용도를 중심으로 분석하였다. 분석 결과 성별에 따라 남성 중심 업종은 주로 신촌 지역에, 여성 중심 업종은 이화여대 지역에 공간적으로 클러스터되어 있으며, 두 지구의 업종 분포의 차이는 성별에 따른 사회적 활동과 의미와 관련되어 있음을 확인하였다. Urban commercial space has differentiated characteristics by gender, and a variety of urban activities are performed in that space. Notwithstanding the importance of understanding characteristics of urban commercial space by gender, there had been little research in both empirical and quantitative ways. In this regard, the purpose of this paper is to explore the urban commercial space by gender quantitatively. For empirical analysis, Shin-chon and Ewha Womans University areas were analyzed in terms of building transparency, spatial distribution of business and spatial structure, and land use. From the results of the analysis, we could find that the business domain for males is mainly spatially clustered in Shin-chon area, while the business domain for females dominates Ewha Womans University area in a spatially clustered form. Furthermore, significant differences of the land use pattern between two areas are likely to be related with social activities by gender.

Styryl diphenyl phosphine oxide의 가수분해 반응메카니즘에 관한 연구

신갑철,김학진,이광일 慶尙大學校 1985 論文集 Vol.24 No.1

The rate constants for the hydrolysis of p-substituted styryl diphenyl phosphine oxide(p-H, p-Cl, p-CH_3, p-OCH_3) were determined at various pH and rate equations which can be applied over wide pH range were obtained; below pH 5.0 the rate of hydrolysis of p-substituted styryl diphenyl phosphineoxide were catalyzed by hydronium ion and above pH 8.0, the specific base catalysis were observed. However, in the range of pH 5.0-8.0 the rate of hydrolysis were independent on the pH change andno general base catalysis were observed at pH 4.75. The substituent effects on the hydrolysis of styryl diphenyl phosphine oxide derivatives were also studied. On the basis of these results, the hydrolysis mechanism of p-substituted styryl diphenyl phosphine oxide were proposed.

신경현,김준영,윤치순,최창욱,김학현 순천향의과대학 1978 Journal of Soonchunhyang Medical Science Vol.1 No.1

Glomus tbmor of the hand has been well documented lesion that usually presents as painful dermal nodule in the finger. Glomus tumor may be difficult in diagnostic and therapeutic problems because of relatively rare and not easily experienced cases. Normal glomus body presents in the skin and subcutis of the extremity, but the normal body is not more than 1 mm3) in size. Most evidence indicates that the main function of the normal glomus body is to aid in regulation of the skin circulation. The glomus tumor is thought to be an abnormal proliferation of the glomus body and accompained by the classic triad of symptoms : pain, tenderness and temperature sensitivity. This paper reports two cases of glomus tumor occurring in the nail bed and finger pulp. One case was found 30 years later & another case 15 years after the onset in spite of srvere pain, tenderness and lancinating pain when exposed to the cold tempera ture but the excision of the tumor resulted in complete recovery.

하이퍼공간에서 방향 상실 문제를 극복하기 위한 가시화 맵의 사용에 관한 소고

One of the major usability problems with hypertext is the user's risk of disorientation while navigating the information space. Our paradigm is based on the idea of visualization of 'points of interest' which are defined by users. Each point of interest is defined by a number of key terms and a display position. Nodes of hypertext are positioned in the display of points of interest based on the frequency count of word matches in the nodes to key terms in the points of interest. Once visual map is on the display, users can choose one of the nodes and review the contents of the node. By this way, the users can actively decide what they want to see and where to go in hyperspace, so that not only they overcome the disorientation problem, but also study their own interests further.

알루미늄 표면불량 검사를 위한 영상처리알고리즘 응용에 관한 연구

신신범,김학범,이양범 울산대학교 1999 공학연구논문집 Vol.30 No.2

본 연구에서는 알루미늄의 압연 과정에서 발생하는 알루미늄 판재 표면불량을 검출하는 영상처리 알고리즘을 개발하였다. 표면불량의 정상적인 면의 영상과 흠집 영상의 화소 밝기 차이를 이용하여 불량 부분의 경계 부분을 검출하기 위해 다양한 필터를 사용하였다. 먼저 미디언 필터를 이용하여 영상 내의 잡음을 제거하고, 불량의 경계 부분을 강조하기 위하여 Sharpening 필터를 적용하였다. 그리고 Canny 알고리즘을 이용하여 불량 부분의 경계 점들을 검출하였다. 최종적으로 검출된 경계 부분을 포함하는 사각형의 두 좌표를 찾아 원 영상으로부터 불량에 해당하는 영상을 다시 구성하였다. 알루미늄 압연 판재의 서로 다른 표면불량 샘플 4종을 대상으로 제안한 알고리즘을 적용한 결과, 만족할 만한 결과를 얻을 수 있었다. This study is on the application the image processing algorithm for inspection of the aluminium mill strip surface defect. The image of surface defect data was obtained using the CCD camera with the digital signal processing board. The edge was found from the difference of pixel intensity between the normal image and the defect image. Two steps were taken to find the edge in the image processing algorithm. Frist, noise was removed by using the median filter in the image. Canny Algorithm was used to defect the exact edge. The defect image section was separated from the original image is to find the coordination point p1 and p2 which include the defect image. Experiments showed that this algorithm is useful enough to inspect the defects.

중속 디젤 기관에 있어서 저질유 연소시의 排煙농도에 관한 고찰

신학재 木浦海洋大學校 1997 論文集 Vol.5 No.1

This paper describes for exhaust smoke study of degraded heavy fuel oil in medium speed diesel engine with high fuel injection pressure system. The combustion test has been carried out on heavy fuel oil. The smoke density of the degraded heavy fuel oil decreases with increasing the heat release rate at the initial region of the diffusion combustion. It is suggested that the smoke density measured under low load condition was related to the excess fuel in the fuel spray fraction impinging on the piston wall at the time of ignition which was estimated from the fuel spray penetration based on the momentum theory.

객체-관계기반 매핑을 이용한 XML DTD와 관계형 데이터베이스 스키마 생성

신학진 기전여자대학 2002 論文集 Vol.22 No.-

As eXtensible Markup Language becomes the data standard for e-business, the amount of XML data being exchanged grows exponentially. While enterprises may initially conceive of those XML documents and messages as transitory images of data in a legacy infrastructure, a requirement to store that XML data for fast and accurate retrieval is likely. In the paper, we describe the relevant concepts to store XML data into and retrieve them from database. Using the relevant techniques, we fabricate an algorithm to covert DTD to database schema and vice versa. Finally, we brief the current problems and the future studies.

의미적 개념(Semantic Concepts)을 이용한 지식 표현의 형식 규정에 관한 소고

신학진 기전여자대학 1993 論文集 Vol.13 No.-

Currently, there are many researches working on various components for knowledge base system(KBS). Integration of such components is troublesome for several reasons, not the least of which is due to the different terminologies and knoweldge representation formalisms which are used by the various components. A possible solution to this problem is to identify a commonly used set of semantic concepts and then employ this set of concepts to characterize the type of knowledge which is processed by the various components. Choice of an appropriate set of semantic concepts should be based on pragmatic criteria rather than philosophical argument, otherwise it is likely that agreement will be reached on what concepts to inculude. we present a version of concepts which was chosen intuitively. We illustrate how this set might be refined by application to example components of KBSs.

Internet computing will enable large-scale aggregation and sharing of computational data and other resources across institutional boundaries. For this. the concept of GRID is coined. The Grid will not only enable sharing of documents and MP3 files, but also connect PCs with sensors, telescopes and tidal-wave simulators. The Grid, as the next-generation Internet is called, will give researchers intelligent access to information and analysis tools as well as to raw computing power. In this paper, we survey the concept of the GRID and its architecture. Based on the architecture, we study the current issues on the concept and the applications of the GRID. Finally, we conclude the potential and the future of the GRID.
