  • 본문은 동북 3성의 지리, 역사, 연구 상황을 개술하고 착중하여 조선족이 동북 3성에 이주한 시기를 4개기로 나누어 그 분포 특징을 밝혔다. 4개의 시기는 (1) 함풍-동치년 시기 (2) 광서년 시기 (3) 선통-민국년 (4) 위만 시기이다. 매시기마다 조선족이 동북 3성에 이주한 역사 지리적 배경을 천명했고 당시 조선족의 이주 노선과 분포특징을 귀납하였다. (1) 조선족이 동북에 이주하여 온 노선은 모두 20개 노선이 있었다. 그중 이주 수량이 많은 노선으로는 종성-개산툰-용정 노선, 남양-도문 노선, 만포-집안 노선이다. (2) 압록강 유역의 중간진에서 중국 림강에 들어온 이주민이 가장 일찍 했다면 두만강 유역은 10-20년 더 높다. (3) 동북 3성 조선족 인구밀도는 두만강과 압록강에 가까울수록 크고, 멀수록 작다. (4) 압록강, 두만강 유역에는 평안도와 함경도의 이주민이 많고, 두 유역에서 북쪽으로 갈수록 조선 남부의 이주민이 많다. (5) 동복 3성 조선족은 산지보다 평원에 많이 분포되었는데 동북의 수전개발에 커다란 공헌이 있다. (6) 중국 조선족에 97.1%가 동북에 집중되나, 그중에서도 길림성에 1,811,946명으로서 전국 조선족 총수의 65.8%를 차지하고, 흑룡강성에 452,398명으로서 25.2%를 차지하며, 요넝성은 230,378명으로서 9.0%를 차지하고 있다.(1990년 통계) (7) 도시에 있는 조선족은 모두가 잡거하고 농촌에서는 잡거구도 있지만 대부분은 순 조선족 부락을 이루었다.

  • 최근 WEB 2.0 환경을 통해 사용자는 직접 응용 프로그램과 데이터를 이용하여 새로운 컨텐츠를 생산하는 주체로 변모하고 있다. 이러한 사용자의 자발적이고 적극적인 참여는 'UCC(사용자 제작 컨텐츠)'라고 불리는 새로운 문화 컨텐츠의 활성화로 이어지고 있다. 특히 글과 그림, 소리 등이 총체적으로 엮여 있는 동영상 UCC 의 경우, 이야기 구조나 캐릭터가 갖는 내용적인 특성과 제작자의 제작 취지를 훼손없이 살릴 수 있다는 제작의 특성으로 인해 WEB 2.0 환경에서 사용자의 참여가 더욱 두드러지고 있다. 본 연구에서 '사용자들이 열광하는 동영상 UCC 는 어떤 특징을 갖는가?' 라는 질문에 답하기 위해 동영상을 시청하는 사용자의 몰입과 창의성 평가를 진행하였고 이에 영향을 주는 요인으로 동영상 UCC 를 구성하는 내용적인 특성인 이야기의 내러티브와 캐릭터의 과장성을 살펴 보았다. 그리고 이 요인들의 상호작용에 영향을 주는 매개변인으로 제작자의 제작의도에 따른 컨텐츠의 특성을 선정하였다. 제작자의 의도에 따른 컨텐츠의 특성을 분류하기 위해 라캉의 주체이론과 퍼스의 기호학 이론을 바탕으로 모형을 제안하였으며 이를 검증하기 위해 UCC 사용자들을 대상으로 현재 서비스 중인 동영상 UCC 를 보여주고 설문을 실시하였다. 연구결과 제안하는 모형의 적용가능성이 입증되었으며 제작자의 의도에 따른 컨텐츠의 특성에 따라 이야기의 내러티브나 캐릭터의 과장성이 사용자의 몰입과 창의성평가에 미치는 영향력이 다르게 나타나는 것을 확인할 수 있었다.

  • In this paper, a shape decomposition method using morphological operations is studied for decomposing the complex shape in 2-D image into its simple primitive elements. The serious drawback of conventional shape representation algorithm is that primitive elements are extracted too much to represent and to describe the shape. To solve these problems, a new shape decomposition algorithm using primitive elements tat are similar to the geometrical characteristics of shape and 4 scan modes is proposed in this study. The multiple primitive elements as circle, square, and rhombus are extracted by using multiscan modes in a new algorithm. This algorithm have chatacteristics that description error and number of primitive elements is reduced. Then, description efficiency is improved. The procedures is also simple and the processing time is reduced.

  • In this paper, we propose 2D industrial image registration method for the detection of defects. Proposed method performs preprocessing to smooth the original image with the preservation of the edge for the robust registration against general noise. Then, x-direction gradient magnitude image and corresponding binary image are generated. Density analysis around neighborhood regions per pixel are performed to generate feature image for preventing mis-registration due to moire-like patterns, which frequently happen in industrial images. Finally, 2D image registration based on phase correlation between feature images is performed to calculate translational parameters to align two images rapidly and optimally. Experimental results showed that the registration accuracy of proposed method for the real industrial images was 100% and our method was about twenty times faster than the previous method. Our fast and accurate method could be used for the real industrial applications.

  • This study was performed to provide fundamental data for long-term geomorphic predictions of estuarine sandbars in the Nakdong River. We monitored the geomorphic changes of Jinudo (Jinu Island), which is located on the far-southern side of the first western sandbar. We evaluated the temporal and spatial dynamics of the sandbar and the relationship between erosion and deposit speed with environmental factors. We found that: 1) The south side of Jinudo showed very rapid water channel closing and shoal generation. This phenomenon was more obvious during autumn (September and October) than during spring, with greater water depth reduction and variation between sides. 2) The mean deposit speed for Jinudo was approximately 0.85 mm/day. The deposit speed was 1.32 and 1.26 mm/day for the east and south sides of Jinudo, respectively. The maximum deposit and erosion speeds were 27 mm/day and 26 mm/day in July and December, respectively, on the east side of the island. 3) Mean surface deposit size was 0.18-0.26 mm. The newly deposited sandbar had a rotatively larger deposit size than the original land. 4) Correlation analysis showed that, on the southern side of the island, deposit activity prevailed in the winter due to low precipitation and a northerly wind, while erosion was dominant in the summer due to high water flow and a southerly wind. In contrast, the correlation analysis for the eastern side of the island showed that deposition is dominant when water flow is high. These results indicate that geomorphic dynamics vary among island sides.

  • In this paper, we propose cause diagnosis method of semiconductor defects from semiconductor industrial images. Our method constructs feature database (DB) of defect images. Then, defect and input images are subdivided by uniform block. And the block similarity is measured using histogram kai-square distance after color histogram calculation. Then, searched blocks in each image are merged into connected objects using clustering. Finally, the most similar defect image from feature DB is searched with the defect cause by measuring cluster similarity based on features of each cluster. Our method was validated by calculating the search accuracy of n output images having high similarity. With n = 1, 2, 3, the search accuracy was measured to be 100% regardless of defect categories. Our method could be used for the industrial applications.

  • This paper proposes an efficient method for the automatic generation of personalized 3D face model from color image sequence. To detect a robust facial region in a complex background, moving color detection technique based on he facial color distribution has been suggested. Color distribution and edge position information in the detected face region are used to extract the exact 31 facial feature points of the facial description parameter(FDP) proposed by MPEG-4 SNHC(Synthetic-Natural Hybrid Coding) adhoc group. Extracted feature points are then applied to the corresponding vertex points of the 3D generic face model composed of 1038 triangular mesh points. The personalized 3D face model can be generated automatically in less then 2 seconds on Pentium PC.

  • Two naturalized plants (Euphorbiaceae) were recorded from Busan Metropolitan City and from the Jeju Special Self-Governing Province. Euphorbia heterophylla L. (A-me-ri-ka-dae-geuk) was found in a park near Suyeong-gang, Allak-dong, Dongnae-gu, in Busan Metropolitan City. This species is distinguished from E. dentata by its alternating leaves of main stem and glands of involucres with a circular opening. Euphorbia hirta L. (Teol-ttang-bin-dae) was found in Yerae village, Yerae-dong, Seogwipo-si, in Jeju Special Self-Governing Province. It is distinguished from E. hypericifolia as it has capsules with hairs.

  • We reviewed the taxonomic identity and morphological characteristics of Cardamine manshurica (Kom.) Nakai based on its original description and type specimens. Cardamine manshurica, with its smaller flowers and siliques and earlier flowering season, is distinguished from the closely related species C. flexuosa With. This species-level difference is additionally supported in a phylogenetic tree constructed using nrDNA ITS sequences. Taken together, we therefore propose that C. manshurica is a distinct species. The scientific name 'Cardamine manshurica (Kom.) Nakai' is accepted.
