  • As the reutilizing method of exhausted screen, authors used it as a filter and compared with the aluminium filtration. The results are as followed; 1. One sheet of gadolinium front screen has the same radiation absorption as $2.8{\sim}3.3\;mm$ Al equivalent and regular tungsten screen $2.3{\sim}2.7mm$ Al. 2. HVL after Gd-screen filtration was less than the values after aluminium and tungsten-screen filtration. And, image definition with Gd-screen filtration was better than other two cases. Ana surface dose to produce a same film density was more than other two cases. It will be very useful to apply, Gd-screen filter in clinics as it has no deficiency of image quality.

  • Smartphone is integrated into the daily lives of all types of people not even young generation. A touch screen display is a primary input device of a smart phone, a tablet computer, etc. While there are many tough technologies in existence, resistive and capacitive are dominant and currently lead the touch screen panel industry. And a capacitive touch screen panel widely used in smart phones is coated with a material that stores electrical charges. In this study, we tried to manufacture gloves produced with electro-conducting leather as a tool to operate a touch panel screen. Therefore, electrically conductive materials, Polyaniline(PANI), Poly(3,4-ethylenedioxythiophene) (PEDOT), and Carbon nanotubes (CNT) were applied to the surface of leather to be used as a touching operator for capacitive touch screen panel. The leather samples were treated by simple painting method; firstly, they were painted with aqueous solution containing each of the electrically conductive materials and then dried. This cycle was repeated three times. Consequently, the treated leather samples showed electrical conductivity and reasonable working performance to the capacitive touch screen. And, PANI showed the best performance and highest electrical conductivity, and then PEDOT and, CNT in decreasing order. This is because the solubilities of PANI and PEDOT show higher than dispersibility of CNT. Thus, the concentration of conducting polymers was greater than that of CNT in the treating solutions.

  • In the case of Seoul Metro, prior to installation of platform screen doors, had seen 4~6 cases a month of mortal injuries from accidents on the platforms, including suicide attempts towards the oncoming train. However, since the installation of platform screen doors, Seoul Metro has achieved a feat of '0 mortal injuries'. In the initial stages of introducing platform screen doors domestically, due to a lack of experience in controlling platform screen doors, the products were imported and installed through technical cooperations from Japan, France and the United States. Thereafter, following investments in technologies by domestic firms, domestic production of parts such as overall control mechanism, specific control mechanism, RF devices and others were achieved. However, having installed platform screen doors in a relatively short period of time, DCU(Door Control Unit), an integral part of the whole platform screen door system, is yet to be fully domestically produced. At this moment in time, installation is being done with imported products or DCUs developed with DC motors. In this research, advantages and disadvantages of DC and BLDC motors for use in DCU will be analyzed and will produce an own BLDC controlling unit in order to solve any problems arised. Furthermore, the BLDC controlling unit produced will be integrated with DCU to improve the performance of the product and its price competitiveness.

  • 스크린 스포츠 게임은 PC게임과 센서가 결합되어 사용자가 몸으로 직접 게임에 참여할 수 있게 개발된 체감형 게임이다. 2000년대에 크게 유행했던 스크린골프에 이어 2016년부터 스크린야구의 유행이 시작되고 있다. 현재 출시된 게임들은 대부분 전통적인 PC게임의 인터페이스를 채용하고 있다. 그러나 스크린야구의 구질 선택에 있어서 사용자로 하여금 좀 더 직관적으로 조작할 수 있도록 하는 방법이 요구되고 있다. 본 연구에서는 게임과 독립된 키오스크를 활용함으로서 사용자로 하여금 게임의 흐름을 방해하지 않고 게임에 대한 자연스러운 개입을 가능하게 하고 있다. 이와 같이 키오스크를 이용한 인터페이스는 결과적으로 게임에 대한 몰입감을 증대시키게 된다.

  • Purpose: The purpose of this study was to investigate the combined influence of screen based sedentary behavior and sleep duration on obesity, depression, and suicidal ideation in Korean Adolescents. Methods: This cross sectional study used secondary data from the 2013 Adolescent Health Behavior Online Survey. A total of 27,929 high school students were included in the study. Logistic regression was used for analysis of the combined influence of screen based sedentary behavior and sleep duration on obesity, depression, and suicidal ideation. Results: Obesity was more prevalent among adolescents who had ${\geq}$ 4h of screen based sedentary behavior and <7h of sleep duration compared to the reference group, defined as < 2h of screen time and > 7h of sleep duration. Depression and suicidal ideation were more prevalent among adolescents who had 2-4h of screen based sedentary behavior and <7h of sleep duration compared to the reference group. Conclusion: Based on the results of this study, maintaining a low (< 2h) level of screen based sedentary behavior and appropriate sleep duration over 7 hours per day is essential for prevention of adolescent obesity, depression, and suicidal ideation.

  • The screen printing method is much used in the flat panel display field including the LCD, PDP, FED, organic EL, and etc. for forming the high precision micro-pattern. Also A number of studies of screen printing method has been conducted as the method for the cost down through the improvement of productivity. Because of being the dot printing method of the cylindrical shape not being the line printing method like the existing PDP barrier rib and phosphor, the pillar arrays using the screen printing method is deposited in the hemispherical type not being cylindrical shape in the existing printing process conditions. In this paper, the parameters were set on the screen printing device in order to deposit the cross-sectional shape with the cone or trapezoid shape of the pillar in depositing the pillars used the screen printing device for vacuum glazing. The cross-sectional shape slope of the pillar according to the parameters was measured. And analysis the effect of the screen printing process conditions on the cross-sectional shape slope of pillars based upon the result of being measured. The processing conditions were drawn to minimize the cross-sectional shape slope of pillar.

  • 몰입감을 주기 위한 초대형 화면을 생성하기 위하여 원통이나 구 모양의 곡면 스크린의 사용이 증가하고 있다. 기존의 방법에서 스크린을 2차 곡면으로 모델링하여 영상이 스크린의 3차원 평면위에 투영되는 대응점을 찾기 위하여 2차 행렬을 이용한다. 기하학적 영상 보정 후에도 스크린의 모양에 약간의 변화나 움직임이 생길 경우에 2차 행렬이 변하게 된다. 본 논문에서는 스크린의 움직임 및 변화가 작은 경우 약간의 움직임에 의해 변형된 2차행렬을 구하기 위해 3차원 정보를 새로이 구하지 않고, 스크린을 부분적인 평면으로 근사하여 영상의 기하학적 왜곡을 보정을 하는 방법을 제안하였다. 실제 프로젝터로 곡면 스크린에 영상을 투영한 후 스크린을 움직였을 때 스크린의 움직임에 대해 제안한 부분적 평면 근사화 방법으로 왜곡을 보정하는 실험을 통해 스크린이 움직이기 전과 동일한 결과를 얻었다.

  • A folding screen, which spread from china, is varied by many country. Each country make folding screen to fit their culture. Since oriental culture spread to europe, Chinoiserie and Japonism arise in europe at 18C, 19C. Specifically, Chinoiserie arise at 18C, after rococo. And Japonism arise at 19C, after World's fair. But korean culture, even if korea is part of the orient, doesn't found in europe. Korean folding screen doesn't found neither. Chinoiserie and Japonism are not special to oriental people. It's just customs for them. But europe feel it is special because their customs is not familiar to europe. We have to research about our familiar customs and diffuse it to world. That is our task. So this research will compare symbolic meaning and frame between each country's-korea, china, japan, europe- folding screen at formal concept angle. This research will be a basement data about what we concentrate for find korean's own culture style. Because this research is about folding screen, which stimulate western people's interest and has deep oriental color. Also this research help to make modern explication about korean old tradition.

  • Screen splitting is one of the fundamental tasks in different methods including video and image compression, screen classification, screen content coding and the like. These methods in turn support various applications in data communications, remote screen sharing, remote desktop delivery to assist teaching-learning, telemedicine, Desktop as a Service etc. In the literature we find systems requiring splitting assumes a fixed size split that do not change dynamically, also there is no analysis why that split is chosen in terms of performance. By doing mathematical analysis this paper first finds the efficient splitting schemes that can be easily automated to make a system adaptive. Thereafter, taking the screen motion detection as a case study, it demonstrates the effects of various splitting methods on motion detection performance. The simulation results clearly shows how classification performances varies with different splitting which will facilitate to choose the best splitting for a specific application scenario as well as making the system adaptive by providing dynamic splitting.
