  • The major purpose of this study was to explore care giving experiences of mothers, who have their children with borderline intellectual functioning disorder. The core analytical strategy was to find out the essential meaning of caring their children. For this purpose, eight mothers were participated in depth interview, which conducted during October, 2011 through July 2012. The face-to-face interview repeated two or three times based on phenomenological perspective. The interview suggested two major findings: changing mother's view from raising retarded children to caregiving a child with growing-up substantially slow speed; the essence of nurturing experiences for mothers, whose children have borderline intellectual functioning, was to watching with attention rather than advocating ownership. This result can be also found in Barshow's concept of 'watching' rather than 'possession', which is suggested by Tennyson. However, the essential meaning of this concept was associated with 'watching with care', which was originated form Goethe's notion of 'existence'. Mother's of children with borderline intellectual functioning have reached a point of view: when creating a parent-child relationship, it was essential that the child was not 'my child', but was 'a child' per se. This type of parent-child relationship was a result of giving up a desire that the child raised within mother's boundary. It was also a result of psychological warfare and conflict in mother's mind. To internalized this view, it is recommended that the mothers implement the following three perspectives: first, the mothers put down overly-pushed motive toward their children; second, they enhance their level of understanding toward their child; third, it is necessary that the mothers build a new sense of existence through matching their level of concern with their children.

  • Though the Hough transform(HT) is a well-known method for detecting analytical shape represented by a number of free parameters, the basic property of the HT, the one-to-many mapping from an image spare to a Hough space, causes the innate problem, the sensitivity to noise. This basic problem also deteriorates the quality of detected lines and makes the detected line deviated from the real one or generates some bogus, multiple lines where only one real line exists. The size of Hough space also affects the quality of detected lines. In this paper, we analyzed the line distortions in the traditional Hough transform and showed that the distortions are relieved in the edge strength Hough transform(ESHT), which is a modified HT. However the usage of expanded edge and edge strength in ESHT can cause some new line distortions which do not exist in the HT. These new ones can be solved by a proper setting of decreasing and broadening parameter values and the optimal values can be determined only by some pre-determined values. We also illustrated several examples to show the distortion-decreasing property of ESHT.

  • Prostate cancer is a malignant tumor occurring in the prostate. Recently, the repetition rate is increasing. Image inspection method which we can check the prostate structure the most correctly is MRI(Magnetic Resonance Imaging), but it is hard to apply it to all the patients because of the cost. So, they use mostly TRUS(Transrectal Ultrasound) images acquired from prostate ultrasound inspection and which are cheap and easy to inspect the prostate in the process of treating and diagnosing the prostate cancer. Traditionally, in the hospital the doctors saw the TRUS images by their eyes and manually segmented the boundary between the prostate and nonprostate. But the manually segmenting process not only needed too much time but also had different boundaries according to the doctor. To cope the problems, some automatic segmentations of the prostate have been studied to generate the constant segmentation results and get the belief from patients. In this study, we propose an average shape model to segment the prostate boundary in TRUS prostate image. The method has 3 steps. First, it finds the probe using edge distribution. Next, it finds two straight lines connected with the probe. Finally it puts the shape model to the image using the position of the probe and straight lines.

  • 본 논문에서는 경계선 추적에 널리 사용되고 있는 체인코드를 개선하여 윤곽선 추적 시 시간과 메모리 효율을 개선하였다. 일반적으로 정형화된 물체는 윤곽선의 동선이 대부분 이전 검색동선과 같은 방향으로 움직인다. 기존의 8방향 체인코드에는 같은 동선에 있는 경계선이라도 픽셀하나당 한번 씩 검사를 한다. 개선된 체인코드는 확인된 경계영역에서 상하좌우, 대각선 방향으로 한 픽셀씩 더 확인하여 기존 체인코드보다 시간과 메모리 효율을 개선할 수 있다.

  • Prostate is only an organ of men. To diagnose the disease of the prostate, generally transrectal ultrasound(TRUS) images are used. Detecting its boundary is a challenging and difficult task due to weak prostate boundaries, speckle noise and the short range of gray levels. In this paper a method for automatic prostate segmentation in TRUS images using Support Vector Machine(SVM) is presented. This method involves preprocessing, extracting Gabor feature, training, and prostate segmentation. The speckle reduction for preprocessing step has been achieved by using stick filter and top-hat transform has been implemented for smoothing. Gabor filter bank for extraction of rotation-invariant texture features has been implemented. SVM for training step has been used to get each feature of prostate and nonprostate. Finally, the boundary of prostate is extracted. A number of experiments are conducted to validate this method and results shows that the proposed algorithm extracted the prostate boundary with less than 10% relative to boundary provided manually by doctors.

  • A shape optimization problem is formulated to determine the optimal position of heating lines in a compression molding die. The objective of the problem is that the cavity surface would be maintained by a prescribed uniform temperature. A boundary integral equation for the sensitivity of the temperature in terms of hole position is derived using the method of shape design sensitivity analysis. The boundary element method is employed to analyze the temperature and sensitivity field of the die. The sensitivity calculation algorithm is incorporated in an optimization routine. To demonstrate a numerical implementation, an example problem arising in thermal design of a compression molding die is dealt with, showing that the number of heating lines chosen for the die strongly affects the ultimate uniformity of the cavity surface temperature.

  • This paper proposes on the methods of noise removal and edge extraction which is done by eliminating the ambiguities of the image using normalization and minimizing the entropy. Pre-existing methods have their own peculiarities and limitations, such as gray level distributions change very slowly or two regions which having similar gray level distribution are touched. This affects on the post processing such as feature extraction, as a result, this leads to false-recognition or no-recognition. Therefore, this paper proposes on the methods which overcome these problems. Finally, the effectiveness of this paper is demonstrated by several experiments.

How is the inner contour of objects encoded in visual working memory: evidence from holes (물체 내부 윤곽선의 시각 작업기억 표상: 구멍이 있는 물체를 중심으로)

  • We used holes defined by color similarity (Experiment 1) and binocular disparity (Experiment 2) to study how the inner contour of an object (i.e., boundary of a hole in it) is encoded in visual working memory. Many studies in VWM have shown that an object's boundary properties can be integrated with its surface properties via their shared spatial location, yielding an object-based encoding benefit. However, encoding of the hole contours has rarely been tested. We presented objects (squares or circles) containing a bar under a change detection paradigm, and relevant features to be remembered were the color of objects and the orientation of bars (or holes). If the contour of a hole belongs to the surrounding object rather than to the hole itself, the object-based feature binding hypothesis predicts that the shape of it can be integrated with color of an outer object, via their shared spatial location. Thus, in the hole display, change detection performance was expected to better than in the conjunction display where orientation and color features to be remembered were assigned to different parts of a conjunction object, and comparable to that in a single bar display where both orientation and color were assigned into a single bar. However, the results revealed that performance in the hole display did not differ from that in the conjunction display. This suggests that the shape of holes is not automatically encoded together with the surface properties of the outer object via object-based feature binding, but encoded independently from the surrounding object.
