스마트폰 터치를 적절하게 유도하기 위한 GUI(Graphic User Interface)디자인 설계는 사용자들의 상호작용 형태를 기본으로 하고 있다. 그리고 기존 상호작용의 연구대상이었던 WIMP의 디자인 요소를 기초로 하여 터치스크린 GUI 디자인의 변화 형태를 연구하였다. 본 연구는 첫째, 스마트폰을 사용할 때 현실감에 가장 영향을 주는 화질을 결정하는 요인에는 화면의 크기, 해상도, 색의 속성 있었다. 둘째, 적은 공간에서 효율성을 위해 작동되는 디자인 요소 변화로 먼저 윈도우가 사라지고 윈도우의 구성요소들이 기능적 변화를 추구하고 있다. 또한 툴바의 배열이 상·하 배열을 하고 스마트폰의 방향전환에 의한 가로 세로 전환에 적응하는 자유로운 레이아웃 유연성을 갖도록 해야 한다. 셋째, 색채의 경우 사용자들에게 현실감을 증가 시기키 위해 GUI 디자인에서 채도의 차를 낮게 배색해야 한다. 넷째, 사용자와 상호작용을 오로지 GUI에 의존하게 되어 메뉴와 아이콘의 기능 확장이 필요했다. 이러한 시각적 단서는 애니메이션, 재인성, 입체 공간 구성, 강제 지시형식 등을 사용하고 있었다. 이에 본 연구에서는 WIMP만을 그 분석 대상으로 했다는 제한점이 있다. 하지만 스마트폰 터치스크린의 GUI 디자인 요소를 정의하고 발전 방향을 제안하여 차후 스마트폰 터치스크린 GUI 디자인을 위한 연구의 기초를 제공한다. 스마트폰 GUI에서 상호작용을 유도하는 메뉴와 아이콘에 대한 계속적인 후속 연구의 필요성을 제안하였다. In view of proper guidance for using a smartphone touchscreen, GUI(Graphic User Interface) designs are based on types of interactions between users. Moreover, types of changes in touchscreen GUI designs were studied, in consideration of design elements of WIMP that have been subjects for existing interactions. In this study, the results were as follows. First, in case of using a smartphone, determinants of definition that are most effective for feeling of reality were resolution and attributes of color, in addition to the size of touchscreen. Second, as changes in design elements operated for efficiency in a small space, Windows elements are now under functional changes, as well as disappearance of Windows. Moreover, the flexibility of layout is required to be applicable to vertical toolbar layout and horizontal/vertical conversion according to directional conversion of smartphones. Third, for colors, saturation difference must be lowered in GUI designs to improve the feeling of reality for users. Fourth, due to dependence only on GUI for interactions with users, functional expansion of menus and icons was needed. Moreover, visual cues such as animation, recognition, solid space organization and forcible order format were used. Accordingly, this study has a limitation of the only subject for analysis, WIMP. Instead, it made the basis for further studies for touchscreen GUI designs of the Smartphone by defining and GUI design elements and showing their developmental directions. It also suggested the necessity of further studies on menus and icons to lead interactions in Smartphone GUIs.

In the information-oriented society, smart phones are one of the most widely used terminals. Smart phone users want to change graphical user interference (GUI) as they wish according to their purpose or pattern of use. This study examined design elements in the so-called home screen provided as the first interface between a user and a device to understand what elements were regarded by users to be individualized as they wish. This research, to define such design elements for individualization based on user experience and perception, performed documentary study in the 1st phase and conceptualized smart phone individualization and GUI design elements. In the 2nd phase, 190 users who had experiences of smart phone individualization were surveyed to write down in-depth details on what they perceived as design elements subject to individualization. In the 3rd phase, collected replies were assorted under the affinity diagram method. As a result, we could divide hom escreen into a main screen, main menu bar, status bar, and widget and draw user-perceived individualization design elements as shown in 3-2-3. from each divided parts. The user-perceived individualization GUI design elements found out in this study are expected to be significant foundation for subsequent researches on GUI design individualization of smart phones.

확산신경회로망을 이용한 윤곽선 검출 시스템의 광전자적 구현

조철수,김재창,윤태훈,남기곤,박의열,Cho, Cheol-Soo,Kim, Jae-Chang,Yoon, Tae-Hoon,Nam, Ki-Gon,Park, Ui-Yul 대한전자공학회 1994 전자공학회논문지-B Vol.b31 No.11

본 논문에서는 영상에서 윤곽선을 검출하는 시스템을 확산신경회로망을 이용하여 광전자적으로 구현하였다. 확산신경회로망은 확산과정을 통하여 가우스연산과 DOG연산을 효과적으로 수행한다. 또한, 확산 신경회로망은 적은 연결과 고정된 연결세기로 인하여 전기적구현이나 광학적구현에 있어서 LOG마스킹방법을 이용하는 것보다 훨씬 효과적이다. 본 논문에서는 확산신경회로망을 빛의 맑기 분포함수가 가우스함수 모양을 갖는 특성을 이용하여 광전자적으로 구현하였다. 실험결과를 통해 본 시스템에서 윤곽선이 정확히 검출되는 것을 확인하였다. In this paper, we implemented an opto-electronical signal processing system for the edge detection using the diffusion neural network. The diffusion neural network performs a Gaussian and DOG operation efficiently by the diffusion process. The diffusion neural network is more efficient than the LOG masking method in hardware implementation because it has a few connections and the connection weights are fixed-valued. We implemented a diffusion neural network using the characteristics of the light intensity distribution function which is similar to the Gaussian function. We have shown that the system can detect the edge of an image exactly through the experimental results.

In this paper, a noise robust acoustic echo cancellation system is proposed. Original AP(Affine Projection) algorithm has fast convergence speed in colored input signal but has noise amplification problem. So the proposed acoustic echo cancellation system uses Modified AP(Affine Projection) algorithm which normalizes the update equation by adding the multiplication of error power and projection order to autocovariance matrix of input signal. Through various computer simulations, we proved that the proposed algorithm performed well in noisy environment. Simulation results show the improved AIC(acoustic interference cancellation) performance than nlms and original AP algorithm.

Magnetic resonance imaging (MRI) and computed tomography had been used to detect the neurologic lesions of the Behcet`s disease. However, there are a number of cases which can not be detected by conventional imaging studies in neuro-Behcet`s disease. To overcome this problem, magnetic resonance spectroscopy (MRS) has been introduced in several autoimmune diseases involving central nervous system such as neuropsychiatric lupus, but which was rarely performed in Behcet`s disease. In the present study, we report two cases of neuro-Behcet`s disease that showed normal MRI but abnormal proton MRS (1H MRS) findings. MRS in two cases revealed a reduction of the N-acetyl aspartate (NAA)/creatine (Cr) ratio in the substantia nigra and thalamus, respectively, which were the areas without abnormality on MRI, suggesting a functional defect of neurons in these areas. In a case with thalamic dysfunction, abnormal NAA/Cr ratio was normalized in parallel with clinical improvement after treatment with high-dose steroids and immuno-suppressive agents. These observations suggest that MRS may be useful to early detect the functional abnormality in neuro-Behcet`s disease and to monitor neurologic status after treatment with immuno-suppressive agents.

Relapsing polychondritis is a rare multisystem rheumatic disease, characterized by recurrent and potentially destructive inflammatory lesions of cartilaginous structures. All types of cartilage & other proteoglycan-rich structures may be involved, resulting in auricular chondritis, laryngotracheal chondritis, ocular symptoms, vasculitis, cardiac abnormalities, skin lesions and glomerulonephritis. The disease may be associated with another connective tissue and autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, Sjogren`s syndrome and systemic vasculitis. We experienced a 69-year-old female patient who had been previously diagnosed as Sjogren`s syndrome, presenting respiratory tract involvement, episcleritis, auricular chondritis and vestibular dysfunction.

The purpose of this study about systemicity about action composition of poomsae, search problem of poomsae about points that should be recognized and is fertilized and supplement. Through this study conclusion that appear is as following; (a). All actions of Taekwondo may be possible with specialization of all technology actions of Taekwondo through poomsae practice though is included in poomsae. (b). Taekwondo standardization done martial arts be now continuously development of new technology accomplish. Therefore, though inflection of special procurements actions that action more than two is mixed becomes more much, development of more various and new Tackwondo technology may be available. (c). Present Taegeukpoomsad change of arrangement of action from Chapter 1 to Chapter 8 It only difference of each poomsae clear characteristic appear. Therefore, philosophy of poomsae escapes in speculative dead face and to the philosophy department though does appear within poomsae practice, clear difference may have to appear in each poomsae action composition. (d). Because degree of difficulty of action that appear in Taegeuk shape is no alternative difference from Chapter 1 to Chapter 8. gradual technology learning is not consisting. (e). Have controversial point that composition action number of Taegeukpoomsae sees general levels of 25 interior and exterior and poomsae depends on change of arrangement of action. Therefore, it is reasonable number that increase too step by step gradually of composition action. (f). Because it is no techniques·composition·presentation of correct standard about emphasis that is factor who decide banishment of present poomsae, individual analysis is available. But, can understand easily each poosae practice purpose though correct presentation for target of each poomsae is accompanied, and may equip unity is to poomsae practice method. (g). Also, there is no standard presentation of center transfer by poomsae progress when preview poomsae. That is, because there is no reference for east of feet central axis at link of progress direction conversion or action, case that master "主" that is not wage "主" that is poomsaeline of Taegeukpoomsae is make is most. (h). Finally, study about seo-gi may have to consist variously.
