This paper describes ASIC design for brightness revision control, A LED Pixel Matrix (LPM) design and LPM in natural color LED vision. A designed chip has 256 levels of gradation correspond to each Red, Green, Blue LED pixel respectively, which have received 8bit image data. In order to maintain color uniformity by reducing the original rank error of LED, we adjusted the specific character value 'a' and brightness revision value 'b' to pixel unit, module unit and LED vision respectively by brightness characteristic function with 'Y=aX+b'. In this paper, if designed custom chip and brightness revision control method are applied to manufacturing of natural color LED vision, we can obtain good quality of image. Furthermore, it may decrease the cost for manufacturing LED vision or installing the plants.

The most important thing in the garments enterprises is fast reaction. Expecially in the China has both many population and large territory, so each region of China, for instance, northeast, northwest, huanan, huabei, has various climate and considerably different temperature. As a result China garments enterprises require different clothes at the same time. This study build a reliable market-response process as a sub module of SCM that lay emphasis on production and sale cope with specific character of China. This process build a information chain including manufacture-planning, manufacture-ordering, production, arrivals of goods, distribution, sale, sale-evaluation, cross shipment, supplement shipment, and ordering popular goods and similar products. As a result of those, the focused points of this process are real time data gathering and various analysis of data, so it can be possible supporting more faster and more accurate market decision making system and our proposed goal is accomplishment of management profit.

This design plan aims at the designing of the pharmacy counter as the space in which the two inter-related elements of the pharmacy, for example, the pharmacist and the customers, selling medicines and transmitting health informations, etc. keep in contact with each other. To create an ambience of intercommunication for health care and relaxation, it must be set up the basic concepts like Functionality, Flexibility, Transparence and Material-Change. As the design solutions : - first of all the long counter must be divided into the independent places with character and function. - in accordance with the basic concepts functionality and flexibility each small counter must represent a one's own form language that is determined according to a given function and also open and flexible to the change of the situation. - the various kinds of display module are introduced to bring out the functionality and the aestheticity simultaneously. - to make a contrasting image to each other various materials are arranged on and around the counters.

This paper proposes a new method for the digit recognition on a 7-segment display. The proposed method uses morphological processing that dilates segments of digits and connects them into strokes. The digits are extracted by connected component analysis and finally, template matching method recognizes the extracted digits. The proposed method is implemented using C language in Raspberry Pi 4 system with a camera module for a real-time image processing. Experiments were conducted by using various 7-segment LED displays and 7-segment mono LCD displays. The results show that the proposed method is successful for the digit recognition on the 7-segment displays.

현대의 PC 환경에서 사용자 인터페이스의 변화는 계속하여 발전할 것으로 기대된다. HCI 전용 인터페이스는 종래의 CLI; Command Line Interface의 시대에서 MS-Windows 기반의 Graphic User Interface의 시대로 전환되어 왔으며, 가까운 미래에는 NUI; Natural User Interface의 시대로 도래함은 부정할 수 없는 현실이다. 미래에는 전통적인 표준 입력 장치인 키보드, 마우스를 탈피하여 새로운 개념의 입력 장치들이 개발되고, 터치 방식과 같이 인간의 직관적 인지능력을 흉내 낸 인터페이스로 발전할 것이다. 본 논문에서는 NUI의 사례 연구로서 닌텐도 WiiRemote를 Bluetooth와 함께 PC에 연동하여 차세대 인터페이스인 PC Controller를 설계, 사람 제스처를 통한 자연스런 한글입력의 가능성을 제안한다.

For a long time, CAPTCHA Recognition has been a major challenge in the field of artificial intelligence. Although there are many related technologies that can solve this identification problem, further breakthroughs are still needed. Based on the existing SSD network, this paper adds a non-block module. Compared with the original SSD network, the recognition rate of SSD + Non-local is improved from 86.12% to 88.47%.In addition, it is worth noting that the recognized character verification code consists of Arabic numerals, uppercase and lowercase English letters.

Digital content increased much according to the development of an information technique and internet. Many content services are appearing therefore. These would be provide customized digital content to satisfy user request following specific character of user. A digital content must be provided to the structure to be standardized for this. The expression is possible this in MPEG to DID of MPEG-21 framework which is processing the standardization. In this paper, We designed and implemented module that possible to create meta data and to package Digital Item via MPEG-21 DID Standardization based on selected information of consumer.
