  • The purpose of this study was to find out the subjective cognition-patterns of school aged children with borderline intelligence function to the School using Q Methodology. Q-sample was included 21 statements obtained from literatures and in-depth interviews with 4 specialist & 4 children with borderline intelligence function. P-sample was consisted through the consent of 18 children with borderline intelligence function and their parents. The 21 selected Q-statements were classified into a normal distribution using a 5 point scale. The collected data analyzed using a Quanl PC program. This study found out two subjective cognition-patterns of school aged children with borderline intelligence function to the school. Two types were 'participatory & dependent type', and 'onlooking & atrophic type'. This research finding can be used to make clear understanding on diverse voices of school aged children with borderline intelligence function to the School. And this result will attribute to mediations of educational welfare practice for maintaining a safe & healthy learning environment.

  • In this paper, we propose a boundary based marker binary coding method for augmented reality games, which enables the marker-area to be binary coded well in any lighting environments. First, it detects the boundary after transforming an original marker image to a gray scale image, and it executes 4 way pixel extensions for all boundary pixels in order to make the boundary to closed area. Next, for all boundary pixels it compares the brightness of right and left ones of each pixel and allocates black for the lower side and white for the higher side by filling inside area thru the seeded region growing. Experimental results showed that our proposed method produces a good binary marker image recognizable in various light environments. In addition, it showed the possibility of real-time calculation by considering the result of operation speed which is 51 fps for VGA image.

  • In this paper, we propose a method that segments the image, extracts its slope and compensate it in the image that text and background are mixed. The proposed method uses morphology based preprocessing and extracts the edges using canny operator. And after segmenting the image which the edges are extracted, it excludes the areas which the edges are included, only uses the area which the edges are included and creates the projection histograms according to their various direction slopes. Using them, it takes a slope having the greatest edge concentrativeness of each area and compensates the slope of the scene. On extracting the slope of the mixed scene of the text and background, the method can get better results as 0.7% than the existing methods as it excludes the useless areas that the edges do not exist.

  • In this paper, we propose a smoke detection method using region growing method in outdoor video sequences. Our proposed method is composed of three steps; the initial change area detection step, the boundary finding and expanding step, and the smoke classification step. In the first step, we use a background subtraction to detect changed areas in the current input frame against the background image. In difference images of the background subtraction, we calculate a binary image using a threshold value and apply morphology operations to the binary image to remove noises. In the second step, we find boundaries of the changed areas using labeling algorithm and expand the boundaries to their neighbors using the region growing algorithm. In the final step, ellipses of the boundaries are estimated using moments. We classify whether the boundary is smoke by using the temporal information.

  • 최근 IT 기술이 융합된 지능형 자동차 기술에 대한 관심이 높아짐에 따라 이에 대한 연구가 활발히 진행되고 있다. 차선 검출은 지능형 자동차의 주요 과제인 첨단 안전자동차 기술의 핵심적인 부분으로 국내외에서 다양한 방법들에 대한 연구가 진행되었다. 차량의 안전을 향상시키기 위해서는 충분한 제동거리 확보가 가능한 거리까지 정확하고 빠른 차선 검출이 이루어져야 한다. 기존의 경계선 검출기반 차선 검출은 소실점 근처에서 경계선 검출이 이루어지지 않았다. 이는 차선과 도로의 색이 잘 구분되지 않는 채널을 사용하는 문제에서 기인한다. 따라서 본 논문에서는 선형 판별 분석 기법을 이용하여 차선과 도로 색을 가장 잘 구분할 수 있는 RGB 가중치를 계산하여 이로부터 projection 영상을 만들고, 변환한 영상에서 경계선 검출을 수행함으로써 보다 정확한 경계선 검출 결과를 얻는 방법을 제안한다. 제안한 방법으로 얻은 영상과 기존의 흑백 영상에 동일한 경계선 검출기를 적용하여 성능을 비교하고, 이를 적용한 차선검출 실험결과를 제시한다.

  • The proposed paper proposes an algorithm that automatically extracts the region of interest using image processing techniques for medical images. In general, the robust boundary segmentation technique provides robust and accurate segmentation results in object boundaries with various noise and direction generated during image acquisition through optimal segmentation of the edges considering noise characteristics and directionality in noise images. In this paper, it is possible to apply adaptive filter type and size to the structural information of the image object and apply it to the boundary division of various object objects. In addition, it is possible to divide the boundary between various noise images such as an ultrasound image and an optical image.

  • This paper analyzes Gloria Anzaldua's borderland proposal through her work Borderlands/La Frontera (1987). One of the strong trends of US geographical imagination started from the concept of 'city upon a hill'. It left an important footprint in the American history. In the area of international political history, it was the starting point of the isolationism policy. But, this imagination is contradictory because it has exercised the bordering power that demarcates the border and overpasses it as needed. Anzaldua's geographic proposal consists of transformation of the border into the borderlands. This is a challenge to the bordering power and a challenge to the geographical imagination that has led to isolationism, and ultimately a history war. This is not only a nationalist war aimed at the Chicano's restoration but also a war that can measure the American society's possibility of change in the future.

  • This paper proposed a Systolic Arrays architecture for computing edge detection on images. It is very difficult to be processed images to real time because of operations of local operators. Local operators for computing edge detection are to be used in many image processing tasks, involve replacing each pixel in an image with a value computed within a local neighborhood of that pixel. Computing such operators at the video rate requires a computing power which is not provided by conventional computer. Through computationally expensive, it is highly regular. Thus, this paper presents a systolic arrays for tasks such as edge detection and laplacian, which are defined in terms of local operators.

  • The present study was aimed to verify the mediating effect of mentalization and mindfulness in the relationship between secure attachment and borderline personality traits. To this purpose, a self-reporting survey were conducted to universities and general companies in Seoul and Gyeonggi, so the final 358 data were used for analysis. Questionnaires including attachment type, mentalization, mindfulness and borderline personality traits were administered. A data was analyzed by a descriptive analysis, correlation analysis, and a structural equation model using SPSS and AMOS statistic program. A summary of the research results are as follows. First, in the results of the correlation analysis on the primary factors, secure attachment, mentalization, mindfulness and borderline personality traits had a significant correlation. Second, a dual mediation effect of mentalization and mindfulness was shown in the relationship between attachment and borderline personality traits. An secure attachment effect on the borderline personality traits through mentalization and mindfulness. Lastly, the significance and limitations of this study was discussed, as well as proposals for future research.
